Impressive sound from small package.

Moises from Chesapeake, VA on 4/15/2017

Crutchfield Customer Review (What's this?)

Was great but only lasted a little over 4 years. Have to buy a new one now.

Pros: Sounded great and took up little space.

Cons: Lasted only a year after warranty expired

iffy - sometimes nice and sometimes not so nice

allen from salisbury, nc on 9/8/2014

Crutchfield Customer Review (What's this?)

Good out of the box but a year into this and warranty has expired, this unit works when it wants to. Installed in a jacked-up Jeep Wrangler with 35's may be to much for it. If I hit a good bump it can blast, but also if I hit a good bump, it can go out completely or only half power with a distorted sound. I feel it may be time to abort this sub and get an upgrade. On the positive side, this unit is compact and doesn't take up a lot of space.

Pros: compact design, easy to install, remote gain control

Cons: works sometimes

Only so-so

Matt.C. from Vancouver, WA on 12/19/2013

Crutchfield Customer Review (What's this?)

I expected better. Not a super bone-jarring, fat-jiggling mega bass, but certainly a tighter thump than the muddy rumble that now sits behind my seat. You can do better, so keep looking... I got this to fill out the low-end in my commuter car (very short commute) without spending a lot or using up valuable space. Doesn't so much do that for most music as wash out the low-end with either too much rumble or not enough bass. I intended this to go under the passenger seat of my Subaru Outback, but it does not fit--even though it was supposed to. So, it now sits behind the seat and under the floor mat, so mostly hidden, but I do need to remove it on rare occasions when I have three passengers. I probably should have returned this but that felt like giving up on ever getting bass in that car without a lot more effort and expense. I did find that turning this thing upside down and playing a lot with the phase greatly improved the sound. I had to make a little stand for it so there is about a 1.5" gap between the floor and the speaker grill. I have really liked the Sound Ordnance amplifier I have (M-4075). Just a fantastic value and still can't believe the power I get from the bridged rear channel to a subwoofer. Dang, wish I could have done that for this car.

Pros: small(ish) package with integrated amp sounds way better upside down

Cons: doesn't sound near enough as good as it should not as small or thin as you might think

Sound Ordnacne B-8PT

Mike from Daytona Beach FL on 9/30/2013

Crutchfield Customer Review (What's this?)

Perfect little Sub. I wanted a bit more bass without major cost or having to install an amp and a sub unit. This was the perfect solution. It is installed behind the passenger seat of a 2001 Mazda MX-5 and the fit is perfect. Installation was very easy since the battery is in the rear of the car. Great little box!!!

Pros: Size, ease of install, flexibility with the remote volume control, sound quality is great

Cons: not booming bass

Quality build

Seems to be a solid piece but its a bit to boomy for me. i was able to swap this with a Rockford Fosgate piece that worked very well.

Pros: Compact and easy to wire

Cons: Too Boomy

Great subwoofer in a nicely sized package.

Pros: wired gain adjustment



Jerry C from Jacksonville, NC on 8/10/2013

Crutchfield Customer Review (What's this?)

For what this thing is, I was amazed at the quality of sound that came from it. I have to be honest, when my advisor recommended this, I was skeptical. However, the price was low enough and the Crutchfield return policy is good enough to give it a try. My equipment: I'm running this from a Kenwood KIV-BT901head unit in a 2005 Dodge Ram 1500 Quad Cab using the RCA sub out and the amplifier power control wire. Anyone who knows anything about a Dodge Ram 1500 Quad Cab is that there is a very limited space to install equipment. Your options are a form fit sub box under the back seats or under the drivers seat. Dodge put the tire repair jack under the passenger seat. This fit perfectly under the drivers seat. I ran a 6" ground from the drivers seat rail bolt and all the wiring through the precut hole in the carpet for the power seat controls. The sound: It's not a competition band pass box, so don't expect super lows and nosebleed bass. Once I set the subwoofer crossover information on my head unit (80Hz@ 18dB/octave slope), I followed sound ordinance's guidance for setup. The sound is amazing for what I listen to (Metal, Hard Rock, and some more Pop type stuff when my wife is in the car). It compliments my highs/midrange well and doesn't distort at high volumes.

Pros: 1. Extremely small size fits great under my trucks driver seat; 2. Easy install and setup; 3. Affordable bass addition

Cons: Looking at this item for what it is and what it is intended for, I can't legitimately find anything wrong with it. The manufacturer clearly states the frequency range at 80-200Hz which is not deep bass. Understanding this will give you a better idea of what you're buying. Compare it to a really nice computer subwoofer but better.

Just what I was looking for

T1no33 from Tampa, Fl on 6/10/2013

Crutchfield Customer Review (What's this?)

If you're looking for earth shattering bass that people hear a block away go buy something else. If you're looking for a great little powered sub to enhance the sound quality in your vehicle and get that extra punch out of things this is EXACTLY the product you are looking for. I am a 42 year old man that enjoys, rock, metal, country, hip hop, jazz, etc, etc and I found this little sub to make it all sound that much better in my vehicle. I have also NEVER installed anything in any vehicle I've owned out of fear but this was truly easy. I had to call Crutchfiled Support once and they were AMAZING!

Pros: - easy installation - good price - good bass for unit

Cons: - didn't fully fit underneath my car seat

Good sound and fits into small spaces

No hardware included to mount unit! from Illinois on 6/2/2013

Crutchfield Customer Review (What's this?)

I needed a small powered subwoofer to install in a 370z Roadster. This one was just the right size but still not able to fit under a seat. I was very surprised to find that there was absolutely no hardware included to actually mount the unit. I'm assuming that they figure you will just press fit it under your seat.

Pros: Nice tight base sound.

Cons: No mounting hardware. This should be noted in the description.

New 8" sub

SimonSays from Armed Forces, AE on 6/2/2013

First, I have been impressed with Crutchfield's aftercare. I called for help and the technician was excellent. The product has been great. Very simple install, easy setup and a pleasure to listen to in the car. So far, I would recommend this product.

Pros: Size, price and easy to install. It rounds out factory speakers pretty well.

Cons: If you enjoy bone rattling low bass, this is not for you; however, if you have a daily driver with children, and a passion for music, then this is for you. Super low bass just is not there.

Crutchfield Customer Review (What's this?)

Installed in truck under passenger seat. Sounded awesome. Unfortunately the subwoofer blew after a week. going to see if i can return it. If yours doesn't blow the speaker, you will definitely enjoy it.

Pros: Sound

Cons: Speaker blew before i even had it a week.

Nice sub for the money.

Pros: Great additional to a factory system.

Cons: Not much in the lower bass (Hz) range but still worth the $$

Crutchfield Customer Review (What's this?)

NIce product, small footprint. Fills in the bass very nicely.



Very good to give music a boost.

J J from Middle tennessee on 5/23/2013

Crutchfield Customer Review (What's this?)

Product does exactly what I wanted. Makes music fuller and richer sounding. The only problem is there is no way to mount this product.

Pros: Sounds great makes music richer.

Cons: No way to mount.

perfect addition

Rick M. from Sartell, MN on 5/22/2013

Crutchfield Customer Review (What's this?)

Paired with the current system I installed myself thanks to Crutchfield's Master Sheets (Alpine CDE-HD138BT receiver Boston Acoustics SC 65 front 746 back) in my 2000 Silverado. It is the perfect compliment to an already quality sound system with hard, clean, steady bass. Placed in the back, under the seat, it is neatly hidden, but lets the listener know immeadiately that it means business.

Pros: Small compact powerful priced right

Cons: none

Not bad at all

Sean from Ocean Park, ME on 5/17/2013

Crutchfield Customer Review (What's this?)

Like a lot of the reviews said. Not going to blow out any windows, but rounds out the sounds nicely. I would buy it again, good value. Installed in a soft top wrangler.

Pros: Good sound, small enough to fit under the seat

Cons: None yet

Crutchfield Customer Review (What's this?)

very good subwoofer, Crutchfield is very good service and on time delivery, compact but powerful I install it in my tundra it is working very good perfect sport for it.




Nooly from Iowa on 5/14/2013

Crutchfield Customer Review (What's this?)

I purchased this unit based on the positive reviews, and for the ease of installation of a powered subwoofer. This product sounds ok when there's no road noise, but once you get moving it's hard to hear without cranking it up. The problem then is you have a noticeable amount of distortion. The product fit underneath my passenger seat, which made installation fairly simple. Unfortunately, the end result is what I would consider less than satisfactory. I purchased this unit so I wouldn't have to build a custom enclosure for my application. I almost wish now that I had gone a different direction.

Pros: Easy installation

Cons: Too much distortion when it's turned up enough to hear it over the road noise

GREAT addition

martinfan30 from Carson City, NV on 5/13/2013

Crutchfield Customer Review (What's this?)

VERY happy with the bass this unit puts out for my extended cab silverado. Doesn't shatter windows but makes my metal and rock sound like it should. Very happy and highly recomend.

Pros: Sound, size

Cons: NONE for me

Great Boom for the Buck

TimK from Coatesville, PA on 5/13/2013

Crutchfield Customer Review (What's this?)

I bought this powered sub mainly because of price and size. It is connected to the factory JBL sound system in my 2004 Toyota Tundra Double Cab and really packs a punch. I installed it under the driver's seat and was able to fit it in w/o losing the rear-mounted heat ducts which seems to be pretty common w/ this location. The installation was a snap, but I couldn't have done it w/o the help of EdB in Tech Support. He sent me a wiring diagram and pics of my interior that allowed me to tap into my factory-installed amp behind the back seat, instead of the head unit behind the dash. That alone saved me TONS of time and helped me get it done much quicker than I had expected. I've yet to "tune" the sub correctly, but I'm definitely happy w/ the results I'm already experiencing!

Pros: Price, size, bang for the buck

Cons: None that I've experienced

perfect size for 2011 ford f150 Lariat super crew

Bets from minnesota on 5/11/2013

Crutchfield Customer Review (What's this?)

this the perfect size to fit under your super crew under the back seat,gives off just enough bass without rattling windows and sounds good and still have the stock radio i also replaced my 4 factory speakers with some 2 way alpine speakers they sound great,i had all this installed at the dealer for a clean look and a huge improvement over the the stock junk

Pros: just enough bass and doesn't take up much room and it hides easily

Cons: none

Seriously Confused About the Positive Reviews

Christopher from United States on 5/9/2013

Crutchfield Customer Review (What's this?)

Ok, wait, no, this is SOOO NOT OK... Do yourself a favor and Look Elsewhere for something different - This S.O. Sub is just that nothing but - SUB-STANDARD Scenario: - Sony BT4000P Aftermarket Head Unit w/ Factory Speakers (not the Rockford System) in a 2006 xTerra - Head Unit has option for "Rear Base Enhancement" which essentailly converts your rear speakers through sound processing into pseudo-subs - obviously on a basic oem factory speaker system this doesn't do much and you tend to bottom out your rears - if not blow them - though it does give a nice thump at low volumes - Head Unit also has full control over Dedicated SUB-PreAmp Out - including gain control, phase control & cross-over points So, you're wondering: "Why is he writing about the head unit?" The RBE option with factory speakers (no actual sub) puts out more base then this sub does when it is totally maxed out and everywhere in-between - except at very low listening (volume) levels. I bought this to replace a VERY old Kenwood 8" Self Powered (30w RMS - 60w Max) Sub Tube which I recently installed in my system which had 20x the bass but sadly due to its age the surround disintegrated from dry-rot but even with the Completely Blown Sub it has more punch then this...

Pros: Not sure there are any... Nice Form Factor?

Cons: Might as well not exist - ZERO - Added bass except at max settings at very low volumes...

Perfect for my Mack daycab truck behind the seat.

Crutchfield customer from Nebraska on 5/6/2013

Crutchfield Customer Review (What's this?)

Better than I expected.

Pros: Small footprint and all connections are in one location.

Cons: No mounting holes, tabs, or brackets included.

Best compact sub out there

Strick daddy from NC on 5/6/2013

Best sub for your money, I've researched a lot on subs. but i have a truck and want to keep my seats open, so my options are very limited. After months of research I found a sub that a lot of people were talking about and that had great reviews. I bought this subwoofer and installed it, turn the sound up(country, soft/hard rock) and it kicked! I have a crew cab so my truck is purdy big and it sounded as good as my friends 10 in JL. Its not over powering but its smooth and packs a good punch

Pros: Has lots of power for a 8in sub

Cons: none

small package, large sound

Crutchfield customer from DuBois, PA on 5/6/2013

Crutchfield Customer Review (What's this?)

I own an 02 Jeep Wrangler. I installed an alpine player and polk speakers from Crutchfield at x-mas time. After the install my factory "sub" stopped playing. After much debating I settled on this sub as my solution. I couldnt be happier with my choice. My music varies greatly from mine to my wifes and my young daughter. Some people mention it not being a "rattler" but it will shake my mirror without trouble. Plays rap, metal, punk, rock, hip hop, dance, and country all with out issue. mounted the volume control inside my center armrest console. As others have stated it is a bummer about not having mounting tabs, i have it under my rear seat and the fit is tight enough i dont think it'll go anywhere. Used the efx 10 gauge wiring kit, for a flawless install.

Pros: small size, awesome sound

Cons: no mounting tabs

Fits perfect in front of Passenger Footwell 2011 Expedition

Vincentesq from CA on 5/6/2013

Crutchfield Customer Review (What's this?)

I have a 2011 Ford Expedition. I upgraded all four speakers to Infinity and a Kenwood Nav. The sound was missing Bass because this model did not have a subwoofer. I had considered the Bazooka because I have had 2 of those in the past cars, and they were great. On the recommendation of Crutchfield, I purchased this, and WOW! It fits perfectly under the carpet of the passenger footwell. I have a corded control so I can control the bass volume, and at 9 o'clock setting (1/4 of total), the bass is perfect! Turning this to the 12 o clock position gives me heart pounding bass! Compared to the Bazooka, this is just as good. I listen to all types of music, including pops and hip hop. I would highly recommend this, and have just purchased another one for my Lexus Ls 430.

Pros: Compact and fits almost everywhere! Easy installation!

Cons: None that I can think of.

Rock On

wirehead from Cedar Lake IN. on 5/6/2013

Crutchfield Customer Review (What's this?)

Sound Ordnance B-8pt Has excellent sound and pressure ! I like hard rock and metal and this powered subwoofer pumps it out! I bought three of these two for me and one for Carl. We both give it five stars. Thanks Crutchfield for the excellent deals and service.

Pros: Excellent sound, easy install, compact size, remote level control and no distortion.

Cons: No cons.

The Boomin' System

TrevorL from Quartz Hill, CA on 4/29/2013

Crutchfield Customer Review (What's this?)

This system was the perfect fit for my ol' beat up Pickup Truck! The unit mounted right under the passenger seat and the cables under the door trim, through the dash and to the head unit. I drilled a hole in one of the dash 'pop-outs' and mounted the bass level adjuster. I can turn down the bass when I want to listen to the sports talk and pump it back up when I want to bob my head and tap my foot. Thanks Crutchfield!

Pros: Easy installation! Everything mounted easily.

Cons: Had to remove the bench seat. I had never done that before--nothing wrong with the product.

Sound Ordnance Subwoofer

Mark R from Houston, TX on 4/27/2013

Crutchfield Customer Review (What's this?)

The unit first of all came a day early which was awesome. This is the second order in a row that came early from these guys. The sub was exactly as described and has worked great. I have 2002 Mitsubishi Gallant and it really balanced out my upgraded factory speakers and head unit. The front speakers are 5 1/4's and the back are 6 x 9's. I set the crossover point for the sub woofers to just under 200 Hz and the other speakers to just above 180 Hz. The reason I mention this is because I spent a lot of time trying to find the 'peak' crossover point. This works really well for all types of music.

Pros: Beautiful bass and perfect size

Cons: This is an 8" sub woofer that works great in the confined space of the car. If you want the sound that makes your teeth rattle out of your head and annoy other drivers, you might want to use something else.

Great for filling in the bass

Brendan from MA on 4/26/2013

Crutchfield Customer Review (What's this?)

Easy to install under the back seat of my 06 F150 crew cab. Fills in the bass really well with my Pioneer App radio and RF door speakers. Won't rattle the windows but fills out the sound nicely. Love it!

Pros: Small, compact, easy to install.

Cons: None if you don't want to rattle the windows!

Great little sub package

Patrick from Mesa, AZ on 4/22/2013

Crutchfield Customer Review (What's this?)

Great little sub for my Toyota Tacoma. It filled in the missing lows and hits great for its size. Perfect for my truck. Took a little time to tweek the sound but definitely worth it.

Pros: Great for small applications


SO powered sub

Don from Brigham City. UT on 4/21/2013

Crutchfield Customer Review (What's this?)

I installed the Sound Ordinance B-8PT in my boat. I had limited space and that is why I chose it. The install was simple and the results are amazing. I highly recommend this product!!

Pros: Simple install. Great sound. Very adjustable.

Cons: Instruction booklet a little vague

Very good little sub

BrettM from Fremont CA on 4/21/2013

Crutchfield Customer Review (What's this?)

If you are looking for a sub that does not take up too much space then this sub is for you. It fills in the missing bass that my component speakers can't produce. It is just enough bass for me but for some it would not be is not a 10" or 12" seale box base but its not bad



Way more then what I expected.

Mega from Harrisonburg, Va. on 4/20/2013

Crutchfield Customer Review (What's this?)

2012 F350 Standard Cab 4x4. First off like others have said if you want to shatter windows this isn't for you. However in the small standard cab not alot of area to fill. I was supprised for an 8" it does real well. Was the perfect filler for a stock system to get some bottem end. I placed it under my seat wish it had some kinda of mounting system other then velcrow.

Pros: Better then expected for size and power, Great for vehicles for litte to no free space.

Cons: No real mounting options, Took off one star for no mounting options. Other wise pretty nice all in one.

This little sub rocks! Great value.

PaulS from Florida on 4/18/2013

Crutchfield Customer Review (What's this?)

I decided to purchase this sub to add much needed bass to my factory system without sacrificing space. I had it installed by a professional along with a new head unit and I have to say I am very impressed! I listen to mostly rock music but when I turn on hip hop it makes my rear view mirror vibrate. At the current price, it's a great value!

Pros: Sound, takes up very little space

Cons: None so far. Those who say it doesn't sound good must be using a factory head unit or expecting it to sound like two 10s in a box.

Perfect Compact Sub for a Compact SUV

Scott from Sacramento, CA on 4/18/2013

Crutchfield Customer Review (What's this?)

Ideal for what it is, an ultra compact under the seat 8" subwoofer (if you want to call it that). I have not heard other under seat subs, but i would imagine they're not much better than the Sound Ordnance and cost more $$$. I traded my Accord last year (2012) for a new Forester and didn't want to lose cargo space with one of those big, bulky/box subs...the B-8PT model fit the bill perfectly. Plus as i get older, i no longer need the deafening 1000 watt system you can hear a mile away, lol. I had an Infinity BassLink II (a powered 250 watt 10" sub) in my Accord and the B-8PT doesn't perform the same way, and i didn't expect it to. Instead, like a few other commenters have said, the B-8PT has a tight and punchy type bass. Overall, with most of the music i listen to i'm very satisfied with this sub given the price and its compact would be very hard to beat this package. I got mine for $, recycled my Scosche wiring kit from the Infinity sub I had, and paid for the install...not bad for the total price installed. The way the bass performs of course depends a lot on how the music you listen to was recorded, but overall if you're looking for a compact, out of the way sub that will add some really really nice solid lows to your stock sterero, look no further, the B-8PT is a true performer. Like others have said this is not going to shake the doors off your car, but you will definitely feel the bass of course. I have mine under the passenger seat.

Pros: Affordability, strong bass for most music, compact size fits perfectly under my Forester's passenger seat, fun packaging it was shipped in, and just the right amount of power to match with my completely stock stereo.

Cons: Volume knob doesn't have an LED light to see it at night, i've had just a few (maybe three) songs where the sub made the song sound muddled and the bass was overwhelming and hard to listen to causing me to change the song (the settings are good for all other songs though, so that can't be the problem)...very minor, and not enough of an issue for me to knock my rating down to four stars.

Sound Ordnance Does It's Job

paryted from Lanoka Harbor, New Jersey on 4/15/2013

Crutchfield Customer Review (What's this?)

I have this Sub hooked up to a new Alpine media player head unit. The install was straight forward. I put this system in my 2005 Jeep Wrangler because especially when the roof is in the garage during the summer months the sound quality of the stock system is horrible. This addition to my new install makes the kappa speakers installed in the stock spots sound really nice. The audio controls on the sub make it easy to fine tune the sound. They are easily accessible, you do not need a tiny screwdriver to make your adjustments. Overall it's a great product

Pros: Small size, Easy access to the control knobs, Remote control knob that mounts with you to quickly raise or lower the overall volume,

Cons: No spot to actually put screws as to really mount the amp. It comes with a strip of Velcro to attach the sub which I feel is a downer.


Steve K. from Summitville, IN on 4/13/2013

I received my new head unit and speakers from a employee program (AT&T) but still needed a sub after talking to Ryan at Crutchfield he walked me thru my purchase of this awesome powered sub and the install kit for my head unit ....this sub is perfect for my reg cab Chevy truck

Pros: Ez install and setup

Cons: None

Great Product.

Nice little subwoofer, but not perfect.

BLD from Albuquerque, NM on 4/9/2013

Crutchfield Customer Review (What's this?)

I have a 1991 Porsche 944 cabriolet. Even though it has the "upgraded" audio speaker system, it really lacked bass. I had recently upgraded the headunit to a JVC KW-NT3HDT. I upgraded the door speakers as best I could as they only take 5 1/4" drivers. The rears are 4x6 plate speakers. As you can imagine, not much bass. My car has the back seat installed, so no where to install a sub there. I never really heard of Sound Ordnance before but most people seemed okay with them. I bought this unit hoping it would fit under the seat. It did not, even with the seat raised to the highest position. I really did not want to put it in the trunk as it is not the most powerful sub in the world, plus my trunk is small. I ended up modifying some 4" L brackets from Home Depot and installed it under the glove box. It does drop about 2" into the passenger foot well. I left all the settings on the unit in a 'neutral' position as I could control everything from the headunit including the level and crossovers. Once installed I fired it up and man what a difference it makes. This is not going to rattle your windows, but that is not what I was looking for anyway. It nicely fills in that sound gap that was missing with my factory speakers and I could not be more pleased. It would have been ice if they included some way to install the unit other than just putting it on the floor of the vehicle. No brackets, no screw holes, nothing. A big oversight in my opinion.

Pros: Small size, reasonable price, solid construction.

Cons: Auto on feature only works with speaker level inputs not line level, so you have to use the remote turn on wire. The manual is virtually useless. It would be nice if it included some detailed sound tweaking advice regarding the unit's settings and capabilities. The unit does not come with any brackets or even screw holes to attach it which I found odd and disappointing.

Nice unit

Jim from Wilmington, DE on 4/8/2013

Crutchfield Customer Review (What's this?)

Installed this in the cargo area of my 2005 CRV. It would have barely fit under the driver side seat, but I didn't want to sacrifice the rear foot room, or obstruct the heating duuct outlet located there. No matter, it sounds great where it is, even with the roll-up cargo cover extended. As many others have stated, it rounds out the low end nicely, especially in my system with all 6.5" door speakers. But it won't rattle your windows - just nice clean bass. It did take some time to "dial in" properly, given all the controls on the subwoofer as well as the sub controls on my Kenwood head unit. I recommend installing the remote volume knob, as it provides very convenient fine tuning on the fly. I put the knob unit in the samll flip-open cubby in the lower center of the dash. One minor complaint, the only way to anchor the unit is with the supplied velcro strips. The velcro strips stayed stuck to the floor carpet and separated from the adhesive the first time I tried to move it.

Pros: compact size, performance, good controls

Cons: mounting scheme

04 Jeep Wrangler Upgrade

wedu22 from Groton, CT on 4/8/2013

This is actually my second one of these powered subs I purchased through Crutchfield (first one went in my Mazda B2300 pickup. It is perfect where space is limited such as it is in Jeep Wranglers. Easy to install, plenty of power & easily heard when the softtop is down. Love this sub!

Pros: Strong sound & can take a pretty good beating.

Cons: Nothing

Perfect fit

David from Newport News, VA on 4/5/2013

Crutchfield Customer Review (What's this?)

Easy to install behind the seat of a 2011 Silverado Crew cab. Sounds great. A little delay on the turn on using high level inputs from the rear speaker leads. I am not sure if it is a capacitor charging, or the volume just has to be moderatly loud to turn it on. I will update when I hook up the remote line. However it is a great addition to the stock radio.

Pros: Size, sound, volume

Cons: Turn on delay.

Rounds out my sound

Abe from Texas on 4/2/2013

Crutchfield Customer Review (What's this?)

Added the low end I needed. I have Polk db651 up front and db651s in the back of my 2011 Tundra dbl cab. I needed to boost my low end and this did the trick.

Pros: small footprint

Cons: could use a little more gain

Small sub perfect for small SUV

Crutchfield Customer Review (What's this?)

I put this under the driver's seat in my 1999 CR-V. Great sound, easy install. Just know that whoever sits in the back seat will only have 10 inches of foot space.

Pros: Great sound for a little box

Cons: None


SamS from Maryland on 3/29/2013

Crutchfield Customer Review (What's this?)

This is a cool unit! Its small and light for being an all in one unit (subwoofer-amp-enclosure) This guy here is only 120 watts but ir will do the trick, it will surprise you, it will out perform itself in real life vs specs on paper! I put this in a 99 chevy s10 truck with single cab. i installed it right behind the driver seat and it is all good from there. I also installed an Kenwood head unit along with this and the pair are "two peas in a pod". This Sound Ordnance unit will not rattle your vehical but will provide a good "hit" in bass that you will notice. Do NOT put this in a TRUNK of a car and expect to feel the bass something great cause you wont. INSTEAD put it under your driver or passenger seat (if you have a car), or under your driver, passenger or "bench" seat (if you have extended cab truck), or behind/under your driver/passneger seat (if you have single cab truck) and you will love what you have created. This unit is for someone who wants a simple hassle free bass package, wants to round off the current sytem they have with a range from "balance" to "a nice little bumb", and someone who may or may not be tight on available space. This unit is NOT for someone being cheap trying spend less money expecting to get glass shattering bass. If you want that go another direction now, perhaps a "ALPINE" mono amp (500watts minimum) with either "ROCKFORD FOSGATE PUNCH" subwoofer(s), or an "ALPINE SWE", or the "ALPINE SWS" subwoofer(s) and you will be better suited.




JJ from Beloit, WI on 3/26/2013

Crutchfield Customer Review (What's this?)

Easy to connect but large dia power wire (ie 10 ga) causes hold down screw and washer to short out on case (ie sparks). Also, not very loud. Hard to hear bass unless system cranked up REALLY loud...even then not very loud.

Pros: easy ro install and small size fits

Cons: dont like 12V+ screw and washer being so close to case (ie grounds out with sparks). also bass is very subtle (hardly hear it)

lbw from NJ on 3/25/2013

Crutchfield Customer Review (What's this?)

I have a 2012 Rav4 and stock HU, and may eventually get better speakers, but for the time being I just needed something to fill in the gaps and also something that would fit in the cavity space in the back underneath (my spare is on the back of the car). This seems to have fit the bill. It's a great size and the sound has been really good so far, I mostly listen to rock and pop, some heavy metal, some country.

Pros: Great small size

Cons: Couldn't go under the seat which might be a con for some, but since I have the extra storage space in the back, it wasn't a problem for me.

S/O powered sub

pedro from Las Vegas, NV on 3/23/2013

Crutchfield Customer Review (What's this?)

i was looking for a small subwoofer setup that still had some kick to it and the S/O powered sub moore than exceeded my expectations. Perfectly compact that it can fit in plenty of spaces other subs cant, easily removable and of course plenty of bass (not taking the system to capacity it still makes my hatchback shake!). The sound is crisp and clear, little to no distortion plus the bass controller that is included provides you with that little extra to fine tune your sound. Great setup for someone who is looking for just a little bit moore bump to their sound!

Pros: great sound, wont take up much space and can fit in plenty of small spaces, the bass controler is a huge plus in fine tuning your sound

Cons: have not found any yet

Sounds great

Crutchfield customer from Lawrenceville Ga on 3/20/2013

Crutchfield Customer Review (What's this?)

Put this in a Ford super duty crew cab behind the back seat. I had to make a mounting bracket because the speaker case has no mounting screw holes. Would recommend this to others just wish it had mounting tabs.

Pros: Small. Great sound for size and price.

Cons: No mounting screw holes.

Sweet Sub

Mitch C from Lincoln, CA on 3/19/2013

Crutchfield Customer Review (What's this?)

It's not four 15s with an extra battery in the trunk that makes your butt buzz and your ears numb. It IS clean, sharp bass in a very compact unit that adds depth to moderate-volume music. Not quite loud enough for me, but my wife LOVES it!

Pros: Compact size, clean sound.

Cons: n/a

Great Powered Sub

Dustin Layshot from Bakersfield, CA on 3/17/2013

Crutchfield Customer Review (What's this?)

This is a really great powered sub. It's very small and fits right under my seat. It puts out really clean, crisp base. Very surprising since the sub is only a 8". It's nothing that's going to blow the doors off but is perfect if you are looking to add some base to your system. If you are looking for something to pick up low base like in rap, this may not be for you, as it can't grab the lows very well since it's only an 8". But if what you normally listen to has higher base, this is perfect. It's easy to install and the external power level is nice to have. The only thing negative is that it does not have any mounting brackets. So you can't mount it to the back of the cab or to the floor. It may slide around which it does under my seat sometimes. Other than that, I'm very happy with it.

Pros: Price, Power, Small Size, Easy to install

Cons: No mounting brackets

Very good to add fullness

Skeith from Ga. on 3/15/2013

Crutchfield Customer Review (What's this?)

Very good sub to help the factory system get the full range sound. Im using it in an 2007 Tahoe with factory door speakers and Kenwood DNX9990HD sounds great but please take the time to tune the speaker it is not plug and play once fine tuned sound great not earth shattering but very good sound inside my suv...

Pros: Size, price and free shipping as well as great custumer support from crutchfield.

Cons: I wish it was a 12 lol...

Small package, great sound!

Ronnie from Orlando,fl on 3/15/2013

Crutchfield Customer Review (What's this?)

Great bang for the buck. Outfitted my car with all new components running off a four channel amp. Did not want to get a separate amp for the sub or sacrifice my storage space In the car but wanted good sound quality. This product completely met my expectations! Sounds great and really enhances the low end which I would not have been able to achieve without this addition.

Pros: Small package, good sound quality, loud if you want it to be.

Cons: Missing that real low end I used to have with my jl audio w7 and dedicated amp.

Great Value OK SOUND and PUNCH

Jody B from Somerset, KY on 3/14/2013

Crutchfield Customer Review (What's this?)

A great fit for a pick-up cab whether it's standard, king or crew. Hides great under my Nissan frontier seat. Did not have to mod anything in the interior. Compliments my Alpine 6.5's great. Mid punch is great, however, 40 HZ and below is not noticable. 50 t0 100 HZ is great with gain all the way up and sub level turned almost all the way up on receiver. I am happy with the sound now but this amp only makes me wish I would have gotten a stand alone amp and a boxed 10. I think for a powered sub that pretty much no work went into to put in, the value is awesome and the sound OK.

Pros: Hides neatly, great sound in small truck cab only, takes up no space at all if installed under the seat, controls easy to get to, seperate gain control you can install in console or under dash

Cons: not loud enough, will make you want a 10, no place for mounts only velcro

Missing Bass Solution

Mike from westminster, MD on 3/13/2013

Crutchfield Customer Review (What's this?)

I'm not trying to scare the neighbors. I just wanted to add the missing bass to my system that the manufacturer does not provide. This was the perfect solution! Easy to install and it adds that lower end which I didn't have with my Honda stereo.

Pros: Small, doesn't take up a lot of space, all in one solution. great price for a powered sub. Crutchfield in general.

Cons: maybe a little more thump

just right

Amazing Powered Sub For The Price

Mike from Bonita Springs, FL on 3/11/2013

Crutchfield Customer Review (What's this?)

Hands down the best 8" sub I have heard in a pickup truck. I have a standard 2002 Toyota Tacoma with no cab. This things fits snug under my seat and has great power. Actually the amount of bass this sub puts out exceeded my expectations. It even hits some of the lows you would expect to hear from a 10" or 12" sub. I also have a great pioneer head unit which helps a lot, but this is one of the best powered subs your going to find for the price.



Decent bass, but not as impressive as the B-8P

CarlL from Auburndale, FL on 3/11/2013

Crutchfield Customer Review (What's this?)

I purchased this powered subwoofer for use in my Dodge Ram Quad Cab. It is very compact and fits sideways under the driver's seat which puts all of the adjustment controls visible when the driver's door is open. I did not use the rotary control knob because the Kenwood head unit I have it attached to has subwoofer level controls built into it. I hooked the subwoofer up using the RCA connectors and it is hooked directly to the battery of the truck for power. Overall, I'm not really too impressed especially compared to the Sound Ordnance B-8P I had in my previous vehicle. The subwoofer started out really boomy and lowering the levels down did help a lot, but it also reduced the amount of bass output. I still have the B-8P that just won't fit into my truck. I will be keeping it to install in a future vehicle because the bass output of that subwoofer is absolutely amazing for the price. If you can fit the B-8P I would absolutely recommend you purchase that one. Buy the B-8PT only if the B-8P won't fit your vehicle.

Pros: compact size, relatively easy install

Cons: not much bass, makes me miss my B-8P

Pros: Small compact design with good sound.


A nice, simple addition!

gtex1970 from ATX on 3/10/2013

Crutchfield Customer Review (What's this?)

This unit is small, affordable and pretty easy to install. It's adds a nice punch to a stock or slightly modified system. I'm running an Alpine deck to Kicker 6x8s in the doors of an F150 SuperCab with stock speakers still in the back. All speakers are powerwed by the deck, no external amplifiers. I use all of the sub controls in the deck and max out the controls on the sub and do not use the sub level control knob. The bass is not deep, but that's what is expected from such a small sub. It's definitely more powerful than before.

Pros: price, size, easy install

Cons: none

Perfect for Jeep Wrangler TJ

Joe H from New York on 3/9/2013

Crutchfield Customer Review (What's this?)

This unit fits perfectly snug under the rear seat of the wrangler. If you have a wrangler you know the roll bar speakers are the only ones that give you any decent sound (forget the dash speakers they only help in imaging). I used this sub with the low level outputs from a sony head unit and the remote turn on power also. I looked at all the options on the web for this type of speaker and am thorougly impressed with the size and clean output of this unit. I bought the reccommended rockford power and signal kit with this #10AWG. The power terminals on the amp require you to use crimp on fork connectors.

Pros: Size, lack of distortion at high output, sturdy construction, ease of installation, easy no tool controls

Cons: none

It's OK, but

David from Atlanta, GA on 3/7/2013

Crutchfield Customer Review (What's this?)

When the subwoofer is on, it sounds great in my Honda Accord EX. It is not a powerhouse, but it rounds out the bottom end quite nicely. When it is on, that is. I suspect that most of the previous 4-5 star reviews are by people who have connected the subwoofer to their head unit's preamp output and the remote wire to the head unit as well. For those of us who use the high-input leads from the rear deck speakers, the mfg had the great idea that they would dispense the need for a remote connection by having the unit power on when it sensed an audio signal. Good idea, poor implementation. The volume has to be moderately high to high before the unit comes on. At moderate volumes the unit doesn't power on at all. If the unit is on but the volume is reduced, after a few minutes the subwoofer turns off. Or, halfway through a song recorded at lower volume, the subwoofer turns off. The only reason I'm keeping it is that it is too much trouble to return.



Great space saving bass filler

Quoc from Pensacola, Fl on 3/7/2013

Crutchfield Customer Review (What's this?)

I wanted some bass in my Subaru Legacy GT wagon, and wanted to place some subs the car without taking away any of my cargo capacity. I measured how much space was under my seats and I saw the spec details of the B-8PT. I figured a pair would fit under the driver and passenger seats. I read the other reviews and decided to try two and I thought it they sucked, I would just sell them on ebay or craigslist. I installed one to hear how it sounded and boy was I pleasantly surprised! After the break in period of about two days, I really enjoy these subs. I only installed one because I found that one was enough for the quality I wanted. I have had 10s and 12s before I didn't purchase these 8s expecting hard thump. They sound great, respond quite well, and still shake(very slightly) my mirrors when I turn up the decibels. I will recommend these to anyone who wants space saving 8 inch subs that provide great filler base to supplement an overall quality stereo system. Oh, they fit under my seats with more room than I was expecting. The sub is 3.5 inches tall and left me with about 1-1.5 inches under my seat.

Pros: Great value, responsive, 3.5 inches tall, easy set up

Cons: Wish they had optional colors but if I want another color bad enough, I could always paint them later. Lacking detail on installation instructions. I I hadn't installed subs before and relied solely on the manufacturer instructions, I probably wouldn't have been able to install the B-8PT in the 3 hrs I used.

Review of B-8PT

Reckon from Huntsville, AL on 3/5/2013

Crutchfield Customer Review (What's this?)

All in all, a great deal for the money. Easy installation (if you can find a place to route your power wire to the car battery) and definitely gives off a noticeable difference in sound when just running an HU an speaker setup. Does very well for music requiring mid levels of bass but as others have mentioned it is not made for music with heavy bass.

Pros: Cost, installation and ability

Cons: Not meant for heavy bass

Sounds Great

H3T from Fresno, CA on 3/4/2013

Crutchfield Customer Review (What's this?)

Exactly what I had hoped it would be. I have a Hummer H3T and had almost given up on installing any kind of subwoofer as there is very little room on the interior. I had to remove the seats to get it in, but it ended up fitting very well. It sounds as expected, not rattling the car next to me, but it is able to pull enough low end out of the door speakers to allow the whole system to sound cleaner, deeper and ultimately louder.

Pros: Great sound from such a small package. Perfect in that it fit in a space that I thought would never have a sub.

Cons: None to mention so far.

Bass Fill

Jordan from Fresno, CA on 3/3/2013

Crutchfield Customer Review (What's this?)

I did a ton of research before making a decision on how to best add bass to my F150 SuperCrew Cab. I already upgraded my speakers to a pair of Kicker 6x9s (front doors) and 6x8s (back doors), and my deck to a Pioneer DVD receiver. While all this fills out the sound well and is a million times better than the stock stuff, I still wanted more bass. After talking to a Crutchfield advisor and doing a ton of research I decided that this should be right for me. And it has not disappointed! While it's not like the crazy bass that my old car had with 2 10s in the trunk, it fills out the bottom end perfectly and still has some hit to it. The versatility of install locations due to the small size is awesome, and the included remote gives instant access to bass control. This is perfect for someone like me who can go between folk, rock, metal, hip-hop, club...basically anything. If you're missing the bottom end in your system, this is a must have!!!

Pros: Small, powerful for the size, fills out the sound.

Cons: None.

Crutchfield Customer Review (What's this?)

I spent over an hour thinking I did not have a good ground at the seat mounting bolt, but it turns out the unit does not turn on right away. Give it a minute or two and turn up the volume to get it started. I have a very good ground now. It fit under the passenger seat in my car easily. I am satisfied.



Great sub for fill in sound

DaveS from Sitka, Ak on 3/2/2013

Crutchfield Customer Review (What's this?)

I installed the SO B-8pt behind the passenger side rear seat in a 2012 Toyota Tacoma Double Cab. This sub is perfect for what I wanted. The install was easy and with a little tuning sounded great. I purchased this to complement my Polk Audio DXI 6500 component and DXI 650s speakers. It provides fantastic base punch without overwhelming the mids and highs. I hooked this up to a Pioneer AVH X5500BHS on the sub preout. It is a great unit with exceptional build quality. I would recommend this powered sub to anyone who is looking for adding an extra punch without taking over your whole system.

Pros: Excellent build quality, easy install and great punch without taking over your system.

Cons: remote gain adjust doesnt seem to do a whole lot unless it is really hitting hard.

Nice punch in a small package

happy_pilot_guy from Columbus, OH on 3/1/2013

Crutchfield Customer Review (What's this?)

I was looking for a way to add a subwoofer to my honda pilot without compromising the storage space. This subwoofer fits under the passenger seat. I installed the subwoofer myself. The install should have been easy - it took me longer because I had a hard time deciding how I wanted to run the power wire to the battery. Make sure you buy the EFX wiring kit - it has everything you need to connect the subwoofer. As for sound: the unit adds a nice punch to the folk, rock and jazz I listen to. I am able to amazing full sound with this unit and the infinity speakers I installed at the same time.

Pros: Fits under a passenger seat, does interfere with storage space. Provides the amount of punch needed for 99% of people.

Cons: For the 1% that want music so loud they will be deaf at age 40 - this unit won't help you pop your eardrum.

Sound Ordnance™ B-8PT

Rob from Baltimore on 3/1/2013

Crutchfield Customer Review (What's this?)

Nice component. It's hard to find a small, powered amp to fit under the seat and this one fits the bill at a nice price. This seems to be very well made compared to the last unit that I tried (Boss Audio) which stopped working twice before it went to the landfill. This unit sounds darn good (not amazing but very good as there is only so much a singe 8" woofer in a small cabinet can do) and the owners manual leaves a little to be desired but I would definitely buy it again.

Pros: Small, well-built, reasonably priced and can really add depth and punch to a factory or small system.

Cons: No cons really other than the instruction manual could be a little more descriptive with installation and tuning.

Crutchfield customer from Ohio on 2/27/2013

Crutchfield Customer Review (What's this?)

Adds a great punch to the kicker components and two ways that I had already replaced my OEM speakers with. Fit perfectly under the seat of my wrx and the remote gain control makes it super easy to tune the base to each individual song.

Cons: None

Perfect Subie upgrade

WJM from Port Townsend, WA on 2/20/2013

Crutchfield Customer Review (What's this?)

As you Subaru owners know, the OEM stereo and speakers are kind of pathetic. This sub produces the perfect amount of bass for anybody that listens to music that involves real instruments. . . This fits perfectly under the seat of a WRX. As long as the seats are not powered that is. And to all you car geeks like myself, this unit barely adds any weight so it's great for an auto cross car, no big boxes in the back slowing you down and sliding all over the place.

Pros: Small, light, sounds great, perfect

Cons: Can't think of any.

Great for the cost!

Crutchfield customer from Bristol, CT on 2/19/2013

Crutchfield Customer Review (What's this?)

As described and reviewed by many others. Be sure to follow the setup as described. I called Crutchfield tech support for assistance with my head unit's crossover settings.

Cons: range, but can't complain for the cost! You get what you pay for :-)

Decent Bass

Eric from Orlando on 2/19/2013

Crutchfield Customer Review (What's this?)

Decent bass for a small, inexpensive subwoofer. It will fill out a stock or slightly upgraded system well. That said, if your door speakers are amped you should look elsewhere for more power. I'm happy for now in my F-150 Screw, but I'll probably build a box and invest in a good 10" and amp soon.

Pros: Inexpensive and easy to install

Cons: Bass doesn't travel. Sounds surprisingly strong in the back of my truck...only fills in the sound up front.

Small But Big Sounding Pounder

C from Casa Grande, AZ on 2/18/2013

Crutchfield Customer Review (What's this?)

I was surprised how well this little sub-woofer sounded! I mounted it under the rear seat behind the driver in my 2004 Avalanche. It connects to a great sounding Pioneer P8400BH, also bought from Crutchfield. It is tight and blends in well with the other Bose stock speakers I have. I like the cutoff frequency and bass-level controls provided.

Pros: Nice, tight-sounding base. Compact low height design fits well in tight locations. Excellent setup controls.

Cons: No cons at all, unless you're looking for window rattling police attention getting bass, which you thank-goodness won't find here!

Stopped working

Darren from Redwood City, CA on 2/18/2013

Crutchfield Customer Review (What's this?)

I really enjoyed this product, it fit where I wanted it to go and it sounded good, when it worked.. I'm now on my second unit in two years and it's stopped working (again)... The first one stopped and Crutchfield replaced it, no questions asked, very nice of them as it had been almost a year. Now I've had this second one for a good while and it too just stopped working... It still gets power and a little (very very very little) noise comes out but, it in effect no longer works at all. I hadn't done anything "weird" with either unit and I hardly pushed it's capabilities, as I listen to mostly softer music styles. It just decided to stop being a subwoofer.

Pros: Fit in small space, sounded ok.

Cons: stopped working way to quickly

THE Cherry on Top!!!!

Rheostatic from Detroit on 2/17/2013

Crutchfield Customer Review (What's this?)

Had a new double-din Pioneer and 4 Rockford speakers. Sounded great but lacked a solid bottom end. Enter the B-8PT and problem solved. Installed in a 2008 F-150 Supercrew under back seat behind driver side seat and truly could not be happier!!! This has rounded out the sound in my truck perfectly, took no time to install and is ideal for my needs. I am not a heavy bass kind of guy but I am now able to control the sub through the Pioneer head unit and can dial it in any way I want. Never thought with the size of this powered sub that it could make as much difference as it has but trust me, it has!!! If you are on this fence about this and are in need of some bottom end to complete your system, grab one of these. The price is fair and I doubt you will be disappointed unless you crave glass breaking, upset your neighbors kind of bass.

Pros: Size, price, quality and Crutchfield Customer Service!

Cons: Sincerely none!

Chevy Colorado install

mojoe from Clayton, NJ on 2/16/2013

Crutchfield Customer Review (What's this?)

I installed this powered sub in my crew cab Chevy Colorado. Blown away by how hard it hits. For a single 8 it does the job big time. Doesn't hit the real low notes but you expect that from a smaller sub. Other than that i am really impressed. If you are on the fence then I'm telling you to jump over. You won't be disappointed. With the generous return policy you can test drive this baby but you'll probably keep it like i did. This sub fit perfectly under the rear seat.

Pros: Hits hard, fast response to bass heavy music

Cons: None really

Robert from San Angelo ,TX on 2/16/2013

Crutchfield Customer Review (What's this?)

For what it is and what I needed, this product is really great. It puts just enough punch in the lower end. A F150 super crew '05 model. Put it under the backseat in the middle, had it professionally installed, cause nowadays with computers and such in vehicles I just did not want to take a chance. Wouldn't mind another but no room as I like what little storage I have.



Amazing sub for the price!

Crutchfield Customer Review (What's this?)

Im a first time subwoofer installer. This little sub is a nice addition to my 98 Jeep cherokee. It provided enough bass to really fill the car. Super easy to install, with a little help from the Crutchfield techs. Glad I bought this! Maybe next time I'll upgrade to something that bumps a bit harder.

Pros: Easy installation, small but packs alot of punch, amazing price

Cons: wish I had gotten one sooner

Happy Sound Ordnance B-8PT customer

wdubose from Dallas, TX on 2/13/2013

Crutchfield Customer Review (What's this?)

Big sound out of such a little package. Put in a 2011 F150 Super Crew. Quite a large interior volume to fill and this does the trick. I wanted more low in with some upgraded door speakers on my stock headunit. Great, crisp sound and plenty of adjustments to get everything right. As others have pointed out the high-level speaker inputs are somewhat difficult to get just right. I went with a remote wire plugged into an accessory fuse w/ the ignition in. Fit it right underneath my passenger seat so (almost) completely hidden. I don't write reviews often but this is well worth it.

Pros: Great sound, big sound for small size, Hooked right up to factory headunit (F150), # of adjustments

Cons: High-level speaker unit was finniky, opted for remote power. Could be a deal breaker for someone without that option,

Fits tight spaces great

MichaelP from Shepherdsville, KY on 2/11/2013

Crutchfield Customer Review (What's this?)

I had this installed under my front seat of a 92 Jeep Wrangler. I went from two 12" kickers in my last vehicle to the single 8" SO B-8PT. It's not for bass heads but sounds great and truly adds just enough of a punch not to have my windows cut open and have it stolen. I would buy it again if a tight space and not over powering bass is needed.

Pros: fits tight spaces

Cons: not for bass heads.

Small package, big sound.

Dave H. from Orygun on 2/10/2013

Crutchfield Customer Review (What's this?)

Installed in a 2012 Ford F150 Supercab. The stock stereo sounded like a clock radio. I didn't want to butcher up my interior and I wanted to keep the stock head unit. So I started out replacing the front door speakers with some Polk speakers. Great, crisp clear sound but still lacking any bottom end punch. This sub filled the bill. My stereo now sounds awesome and I couldn't be any happier. It fits like glove under the front passenger side seat. Some reviewers have reported that the auto sense that turns the sub on didn't always work unless they had the rear speakers turned way up. Wanting to avoid that problem and also because I didn't want to splice into my wiring or use those wire taps for the speaker connections I ordered an amplifier interface. For those that don't know this little device is a box that plugs in between your radio and factory wiring harness. It gives you front and rear line outs and a trigger wire to connect to the sub so that it will positively turn it on. It costs about $40.00. Yes, you do have to remove the radio to install it but it is well worth it. No trying to figure out which wires to tap into. Special note to Ford owners with factory Ford Synch: Some have reported that they experienced problems with Synch if they ran a sub off the front speakers due to the fact that Synch uses the front speakers for its functions. I didn't want my phone calls going through the sub anyway, so I used the rear connections.

Pros: Sounds great!

Cons: None.

Crutchfield customer from on 2/9/2013

Crutchfield Customer Review (What's this?)

If you have limited room and want to have some bass this is the ticket . I still cant belive that much bass comes from this small unit

Pros: Size, the amount of bass

Cons: Maybe a bracket for other mounting options not just velcro or double sided tape

Invisible bass on demand

Jimi Jimi from Annapolis, MD on 2/8/2013

Crutchfield Customer Review (What's this?)

Bought this as an "open box" unit. Condition was perfect and I saved about 10% on the purchase. It fit under the driver's seat of my Subaru Impreza like it custom designed to fit there. After consulting with Crutchfield, I decided to use the remote adjustment knob, sticking it onto the side of the center console under the hand brake. As I tested it with a number of different genres of CDs, I never had to turn it anywhere near maximum to produce a bass-rich sound. The unit fit long-edge-forward, with connections facing the center of the car and adjustment knobs facing outwards where they could be reached (with some difficulty) after the installation was finalized.

Pros: Quality bass sound makes music sound fuller, more lifelike. Remote control makes it easy to add bass for music playback and reduce it for listening to talk radio. No loss us useable space in the car. Easy to connect. Construction seems robust. Terminals are high quality.

Cons: Better instructions on how to adjust this unit in synch with subwoofer adjustments on the head unit would have been useful. Adjustment knobs are tiny and hard to fine tune...making them larger in diameter (10mm) wouldn't hurt the installation but would improve ease of tuning.

Exactly what I was looking for

Steve H from Bentonville, AR on 2/7/2013

Crutchfield Customer Review (What's this?)

If you are looking for a sub to rattle the windows, this isn't the unit for you. If you are looking for a sub to fill in the low end for rock music, look no further. Bought this for my son's car, we had already replaced the head unit and door speakers, but still needed more low end. This unit fit the bill.



Nice Upgrade To OEM System

Chris O from SF Bay Area on 2/5/2013

Crutchfield Customer Review (What's this?)

An easy install under the driver seat of my 1999 Subaru Impreza. Am using the high-level inputs, (as opposed to line-in) because I am running the stock head unit. Sound is nice, but I found that using the "Auto-On" function that detects the incoming signal from the speaker wires only does not turn the sub on reliably, unless the volume is turned up significantly. So, I ran a lead from the accessory line going into the head unit, to turn it on when the accessory power comes on. I put a switch on the accessory input line, before the sub, in case I am not listening to music, I can keep the sub off too. Sound is a very good bass supplement and a fine match with the stock system and the Polk Dxi 650's I have up front.

Pros: Easy to install and sounds very good as an upgrade to a stock audio system.

Cons: Instruction sheet could be more descriptive on how to dial-in the fine tune adjustments, to help a novice installer, such as myself.

Good value...sounds nice in my 00 Silverado

Rich from Cedar Falls, IA on 2/5/2013

Crutchfield Customer Review (What's this?)

I installed this about a week ago in my 2000 Silverado extended cab with a new Pioneer DEH-3400UB CD receiver. Install was easy and it fits nicely under the folding seat in the back. It seems like between the two units, I have a lot of options to adjust the sound settings which is nice. The sound is good and exactly what I was looking for. Kudos to Cruchfield and the rep I spoke to on the phone who recommended this. I love their customer support.

Pros: Easy install

Cons: Wish it came with a way to easily mount it to the floor so it dosn't move around. So far it hasn't but want to make sure it doesn't. Maybe I'll find a cheap velcro solution to get it to stay put.

Great Product, Great People, Great Service

JoshC from Louisiana on 2/5/2013

Crutchfield Customer Review (What's this?)

I want to start off by saying that I am a bass junky, I've installed numerous aftermarket systems in different vehicles and have always used Crutchfield to purchase my products. I recently bought a 2013 Honda Accord Sedan and I was very skeptical about ripping it apart to add the well needed bass. I always research every option in detail before making my decision and thus I came upon the Sound OrdnanceT B-8PT. At first I was worried it wouldn't give me the sound I was looking for but I was wrong, this speaker and amp combo is definitely loud enough for anyone. It will not make you hair stand up but it feels and sounds very powerful. I purchased this speaker because of all the great reviews it received and because it was small enough for me to PERFECTLY fit it under my drivers' seat. The sound is great and it brings that extra detail out of everything I listen too, and I do listen to almost every genre of music. The price was good and it was way easier to install dealing with the smaller gauge wires than some larger systems I've installed in the past. I WOULD recommend this product to everyone looking to upgrade their system without replacing any major components (factory radio, speakers...etc). I would also like to say that I have always and will continue to recommend Crutchfield to everyone looking to upgrade their audio experience.

Pros: Price is very reasonable, sound is very loud and powerful, easier installation, bought it from Crutchfield

Cons: N/A

I had 2 Kicker 8" subs and replace it with the Sound ordnance B-8PT. Man I cannot believe how clear and how it fills the interior of my Chevy Avalanche. I was not looking for trunk rattling sound, I wanted good bass. Sade sounds like she is in my truck.

Pros: Easy in stall, good bass for the style of music I like

Cons: For me none love it

Crutchfield Customer Review (What's this?)

First of all, I'm one to like a good full sound, but not a boomy bass. This sub works great in my crew cab truck and supplements the upgraded door speakers very well.

Pros: Lots of adjustability, small size

Cons: That I didn't buy it sooner :)

Unexpected SUPRISE!

Greg T. from Knoxville, TN on 1/26/2013

Crutchfield Customer Review (What's this?)

I installed this B-8PT in my 98 Chevy Silverado Extended cab, 3rd door truck and I absolutely love it! I first upgraded my Head unit and then upgraded my stock speakers to the RF PUNCH's in both the doors and the rear pillars. (NO regrets at all). The sound was so much clearer and I had much more control on how I wanted my music to sound, but I was still missing my low end, deep base that is needed in music. I am a do it yourself-er, but I still did not want to get into building speaker boxes and trying to fit them under by back seat. So I opted for the B-8PT and love it. This speaker fits perfect behind my seat and still gives me the space I need under the seat. The wired remote control allows me to control the base output when I change between rock and roll to bluegrass to country. This remote works great by giving the opportunity to take out the throaty roar that may come from too much base in a rock song to having that right amount of 'hit' in a jammin' country or pop song. The 'phone cord' is plenty long enough to go anywhere in your truck whether it be below your dash or in your center console. I recently got a friend of mine to listen and he thought I had put in an amp, built a big speaker box and had a 12" sub hidden somewhere. I could not be more happier with the way my truck sounds.

Pros: All the base I wanted and then some. Works perfect in the cab of a pickup truck with limited space. Could see it working in an SUV also.

Cons: The only caution I can give is you may not get the same results from putting this in a trunk of a big car like a crown vic. So if you are expecting a truck rattler or expecting to have to tighten the screws up on your license plate every day then I don't recommend this.

A Great Addition

PhotoArtsLA from Los Angeles on 1/25/2013

Crutchfield Customer Review (What's this?)

I am restoring a classic 1976 Mercedes 450SEL. My first car was also a Mercedes back in the 1970's. At that time a German loudspeaker, the Visonik David, was imported here in the US. This speaker towered above all automotive speakers, and I had them installed. Incredible. In fact, the Visonik David brought the subwoofer into being for home audiofiles (David and "Goliath," the sub designed by the legendary Ken Kreisel... flash forward 40 years, and I actually found the only pair of Visonik Davids in the U.S. - but in 30 years, the David had truly been retooled to work as a satellite which really needs a subwoofer. Enter the Sound Ordnance B-8PT, some custom work in losing the medicine cabinet in exchange for the sub port, and lo and behold, I have once again, arguably, the best sounding car on the road. The weaknesses displayed by all "car speakers" are not there, only the recording studio quality sound I prefer. Visonik Davids are commonly used in mobile recording studios in Europe. Today, I spent four hours in a 2013 Camaro with a top flight Bose audio system, and the difference to my Sound Ordnance enriched Visonik David Mercedes is so striking, our two cars are in two widely separated ball parks. World Class, World Beating sound or my vehicle with Sound Ordnance and the Davids, and Good But Far From Great for the new car and Bose. A Sound Ordnance sub would help the Camaro a LOT.

Pros: Sound Ordnance delivers the missing octaves and presence required by music of every discipline, with a caveat: for those needing the muddy, pointless, throbbing, detail free bass of rap (branded today as Hip Hop except to the performers of whom I have photographed many) this is not your sub, as it is MUSICAL. In a vehicle, only pressure differential bass can be heard. Put a meter inside your thumping car and be amazed at how little bass there actually is.

Cons: There is enough bass to cause a maddening quest to figure out what is vibrating and making noise in an old car. Once cured, bliss returns.

Great value

I installed this in my 2009 Ford F150 STX (stock head unit) along with a Sony XDP-MU110, sounds great ! It will not set off car alarms but it's plenty loud enough for me. Good upgrade for a tight budget.

Pros: Easy install, does what its supposed to.

Cons: Improvements could be made on mounting. Velcro that came with it is weak and there is not enough of it to really hold the box to the floor,

JJ from Mint Hill, NC on 1/20/2013

Crutchfield Customer Review (What's this?)

My decision to purchase this amp was based on the 500+ positive reviews it has received. So after my self installation, I am impressed with the bass it puts out. The bass remote is a plus being able to adjust the woofer on the fly. I was able to install remote in a small knockout on my 2000 GMC Sierra, easily reachable while driving. For someone that wants extra bass but dont want to rattle your neighbors windows this would be a good choice.

Pros: Nice amp+woofer combo, Remote makes quick woofer adjustment. Great for all types of music. It can make your rear view mirror vibrate or it can add just enough pop.

Cons: Using velcro that comes with it to mount is only con I have. Otherwise it just lays under the seat and left with your own imagination to mount it.

Nice Sound

Mike D from Spring, TX on 1/19/2013

Crutchfield Customer Review (What's this?)

My Car - 2011 Toyota Camry SE. The install was pretty straight forward. The hardest part was finding a place to go through the firewall. There is a rubber grommet on the left side about half way down. I had to get a large screwdriver and drive it ALL THE WAY THROUGH to see it from the inside of the car. I then had to feel around for it. It was a lot harder than I expected and took a lot longer than expected too. When I got stuck the Crutchfield staff helped guide me through the process and were very helpful. I installed the sub under the passengers side seat. If you have a Camry there is a flap in the carpet under the seat that has a hole already there so you can screw in your ground wire! Very handy! I didn't have to drill a new hole in the floorboard. I kept my stock head unit so I had to patch in the REM to the gray wire. The only gripe I have is that the B-8PT doesn't have feet, like you'd see on an amp, to screw it to the floor. The velcro just doesn't stop the unit from sliding around. I had to drill my own holes in the unit to keep it from sliding around. I would recommend this unit! Great buy!

This is an excellent item to put in your car if you looking for some extra bass to round out your car system. This little subwoofer actually packs a pretty big punch! I was very surprised with the quality of the bass. It have it mounted underneath my driver seat, so it takes up no space at all. A+ product

Pros: Excellent bass output to round out your car system. doesn't take up a lot of space easy to install

Cons: None

Great addition

KenL from Houston Texas on 1/19/2013

Crutchfield Customer Review (What's this?)

I got this and was concerned about reviews on other sub-woofers like this one being negative. I did not get an install "Master Sheet" from Crutchfield so I elected to have the installer install it for me. He and I both looked at it and laughed a little and after an hour I could hear a booming noise coming from the installation bay. I went over to the window and inside I could see my installer grinning ear to ear and waving for me to come inside the installation garage. One word - disbelief! I could not believe the amount of sound that little 8" powered sub-woofer was pumping out and he had it at the 3/4 mark. WOW, even my Powered Bazooka 6.5 never did that well, I was floored and soon grinning ear to ear with him! What a difference this made. I don't listen to Rap or anything like it but had left it on the Country Portion of my USB stick. The installer said he did not know country had so much bass in their music! To be honest, I did not know either until this S/O sub! I highly recommend this sub, do not hesitate or doubt its ability to do the job, so far I have tested on my country music, Blues, christmas, Vietnamese, and some Rock music, I am EXTREMELY IMPRESSED with this unit. The installer was too that he made copies of the literature before finishing the job so that he could tell his friends about it. I do not know if it will handle Rap or what ever is popular today but it exceeds my needs and expectations.

Pros: Small, fits under seat and does not take up floor space, Boom like nobody's business! Worth every penny you pay for it!

Cons: wife keeps turning it up, going to have to move the remote away from her.

This was an awesome buy. I have a 99 f-250 xlt. I don't have much room anywhere for a big sub system. I ordered the b-8pt and was very shocked how much bass it gives you. I am 18 and listen to rap and courty. The remote bass level makes it easy to turn it up and down. The install was easy. I have never done electrical work in a car and did it all within an hour. Very impressed!

Pros: Small Sounds good

Cons: None

Didn't expect booming bass, but sure does a nice job of filling in what was missing. Ford Ranger Extra Cab isn't big, so this sub makes it self known. Wouldn't fit under the seat, but still easy to hide. Compliments the Alpine speakers I had in the truck very well.

Pros: Nice sound, small size

Cons: Can't think of any.

I bought this for my 16 year old for his birthday. He loves it! He has a 1992 F-250 Regular Cab. We put a new kenwood deck and speakers in and this just topped it off. The sound is great. Not a real hard thumping system but a perfect bass sound for the system.

Pros: Fit, Price, Quality, Sound

Cons: None

Great for my purpose

Don't expect the ground to shake, this is not that. My goal was to round out sound in a stock radio F150 Supercrew. I connected it to a LC2i and tapped into the speaker lines. It works as expected. The case seems tough. It's nice and compact. And adds a fair amount of depth to a sound that was previously very mid and treble biased.

Pros: Fits behind the back seat of F150 super crew Added depth to sound.

Cons: None for my purposes

Great product - great value

Paul S. from Upstate, NY on 1/14/2013

Crutchfield Customer Review (What's this?)

Did not expect so much sound from such a compact unit. Definitely over achieves! Mated in my 2012 Wrangler 2dr with a Pioneer DEH-P8400BH and Polk DXi6500 components up front with Polk DXi650s in the rear. Very satisfied with the power and the sound quality. Crutchfield, as usual, did their routine outstanding job. Despite the small size of this sub, I could not fit it under either front seat. So it lives in the cargo area, pumping out wonderful musical underbelly of my favorite songs! I've seen the reviewers who complain that this sub has very weak output. I can only assume they have become accustomed to the type of bass that you can here coming from three blocks away, or they have somehow totally messed up the connections or settings. Or perhaps a defective unit? Anyone other than bass junkies and true audiophiles should be very satisfied with this sub. I am thrilled!

Pros: Big sound in a small, inexpensive package!

Cons: Didn't fit under my front seat. Oh, well.

powered just right

I really wanted to love it..

Justin C from Minneapolis, MN on 1/14/2013

Crutchfield Customer Review (What's this?)

Lets start by saying this unit is NOT bad. I see most reviews of people who put this under the rear seat in a truck which if that were the case for me I would have probably really liked it. However I installed this under the passenger seat in my 2013 WRX and it just doesn't do it for me. I listen to ALL variety of music and for some it sounded pretty good and others it really missed. Some notes hit and sounded like the kind of bass I expected, and other just sounded like a thud. I think part of that reason is the frequency response only bottoms out at 40hz. This sub just doesn't hit low enough for me and I hate having the bass in my ear as it drowns out my stereo speakers, and if I have the sub lower I can't hear it. Now there are some positives here. While this unit didn't work for me it still produced quality bass for country/rock/pop music. I think this would be a great purchase for someone who listens primarily to rock/jazz/singer songwriter stuff. I will repeat what many reviewers have said. DO NOT BUY THIS IF YOU LISTEN TO RAP OR HIP HOP. It will sound terrible and you will be very dissapointed. It does not hit low enough to produce some of the notes to sound good. This does not produce "feel it" bass, it produces notes just low enough to hear it which is why it will round out your system very well if thats all you are looking to accomplish

Pros: Price, Compact and a great solution to save space and fill out your system

Cons: Frequency response is only as low as 40hz, and you can tell.

Perfect fit good punch really suprised

Pro audio dude from Lakehurst NJ on 1/13/2013

Crutchfield Customer Review (What's this?)

I trust crutchfield so that's 1 of my main reasons for buying this sub. The other is space, this fit perfectly in my 02 ford sport trac in stash compartment behind rear seat. Me personally I ran a dedicated ground line rite to neg terminal on battery I'm all about good quality sound. I have zero feed back or hum when I turn system on or off, I can even power up and power down with volume up and still have a good clean start up and shut down. So going to the neg terminal on batt is a perfect ground and not relying on the car body. I'm a full time hip-Hop head with with a small home studio and I like quality sound and this sub gives me what I was looking for. I also purchased the pioneer dvd1400 pairing this with the sub and all the settings and adjustments on head unit it's a very good combo.

Pros: Punch clarity very good bang for the buck and with the included amp wiring kit for the price it's all pro to me

Cons: The only 1 con is the line jack for the bass control knob was a little short 17 ft would have been perfect but i just ran the line under center console drilled a 1/4" whole near cup holder secured bass controller under center console re-attached bass knob now my set up looks factory/custom. I think I turned my con into a pro

This one's a no-brainer...Great for the investment!

Girtski from Carleton, Michigan on 1/11/2013

Crutchfield Customer Review (What's this?)

This is by far the single best purchase I've made in the last 30 years. I'm an old school rocker who has recently discovered the bass tracks that are on the music I've listened to for years. I didn't want to anger the neighbors or make the mirrors vibrate on the car next to me, just wanted to bring up the bottom end and take a bit of the load off my stock stereo speakers in my 2001 F150. I'm a bit baffled on the multiple settings on the amp itself as to where each should be set but for now it sounds fantastic and the sub control knob is just the ticket for tweaking the bass on each song that plays with the touch of a finger.

Pros: Ease of installation, size, termination of wiring

Cons: Little to no clear reference for settings on the unit. ie, Level, Bass EQ, Phase and Frequency. Also, the posting recommends 8 or 10 gauge wire. I mistakenly ran 8 gauge and ended up splicing down to 10 so I could put connectors on the ends of the wire that would fit in the terminal slots on the unit.

What an awesome product! I have been a long time customer of Crutchfield and and the products and service have never let me down. I read many reviews before getting this sub. I wanted something that would thump but not take up the entire area under the rear seat of my truck. I'll definitely be recommending this sub to my friends. I am very happy with my purchase. Thanks Crutchfield.

Pros: - Small, fits behind the rear seat of my 2011 F-150 Supercrew, with little modification to the interior. - Truck interior looks stock, but thumps. - Free amp wiring kit

Cons: None so far.

Crutchfield Customer Review (What's this?)

This little box is small enough to fit under my seat of my Toyota Corolla and it is big in sound.I had such poor bass from my system before and tried this out and it is remarkable how such a little box added enough bass to round out by system.It is not like a trunk filled full of Woofers, but just enough to make sounds fuller. Nice product at a reasonable price. Big value in a little box.

Pros: Size is just right for under seat placement. Great value.

Cons: None

Great for the money, the free wiring kit is great comes with everything you need to install it. Very compact and great quality. It does not have any way to mount it though, that's a big negative, I had to drill into the actual housing to mount it.

Pros: Compact, good price and wiring kit is free.

Cons: No mounting holes or brackets.

Is bigger better?

MilesW from Ferndale, MI on 1/3/2013

Crutchfield Customer Review (What's this?)

This is a great way to extend the bass of existing system. In my case, I am running fasgates in the door and high Vas speakers in the rear deck. Without the B-8PT the low are actually pretty good. Point being, I should have ordered the 10" version from Sound Ordinance. Nothing wrong with the B-8PT and I like it a lot. Buyers be careful to assess your existing sound before making a decision. Also, your system should have the ability to attenuate base properly so it doesn't interfere with the subs, however some constructive wave forms may increase dB at certain freq.

Pros: Sounds great, easy hook up, well built.

Cons: None really.

Big sound from a compact box!

SteveW from Fort Worth, TX on 1/3/2013

Crutchfield Customer Review (What's this?)

This little sub was just what I needed to replace my old Kenwood Woox powered sub. For me, installation was a snap since I was able to use most of my existing wiring from my old sub. I was able to put this sub behind the back seat in my '02 Nissan Frontier Crew Cab with plenty of room--and it sounds fantastic. The B-8PT far exceeds the performance of my old sub (going from 60 watts to 120). It's nice to have all the sound controls on the sub and of course the level-remote is nice too. I highly recommend this little sub.

Pros: Great sound, small, customizable controls, wired remote

Cons: Wish the remote had more than just the level control (i.e. frequency, phase).

Great little sub

Eddie from Lexington SC on 1/1/2013

Crutchfield Customer Review (What's this?)

Installed this sub along with a JVC head unit and four speakers in my pickup. Fits under my seat. Solid, fills in the bass just like I wanted so I don't have to send bass to the other speakers. Good clean bass. It is not a thumper though. Also, the remote bass level control is surprisingly handy, you can adjust the bass on the fly to fit each song.

Pros: Small, clean bass, Remote bass level adjust

Cons: Won't boom the low lows but that's not what I got it for.

Crutchfield Customer Review (What's this?)

I was completely surprised by the rich thump that this sub provides. The sound ordnance B-8PT was exactly what I was looking for to fulfill my low frequency needs in my quad cab pickup. I like it! 2004 Dodge Quad Cab.

Pros: Compact design, ease of installation, PRICE.

Cons: none

Mo better sound

Jeepman from Westbrook ME on 12/30/2012

Crutchfield Customer Review (What's this?)

After replacing the stock speakers with the Kicker upgrade in my Wrangler I gained a little better sound but not loud enough to over come soft top noise or with the top down, I then put a Kenwood DNX 6180 in the dash . Another small improvement. I then got this powered sub and this was the biggest improvement to my system. I did not realize that it also changes the all over sound in my speakers. I now listen to my music with less volume and much better clarity.

Pros: Doesn't have that banging bass sound.

Cons: None yet

Fantastic for the Buck!

2003 Chevrolet Silverado Ext Cab JVC KWR800BT CD Receiver | Boston Acoustics SE75 4" x 6" Speakers | Boston Acoustics SE55 5.25" Speakers | Sound Ordnance B-8PT Single 8" Amplified Flatsub Honestly...I was completely surprised by the rich thump that this sub provides. Perfect, dial-able amount, for my truck cab. I thought I was going to install under my passenger front seat but has a heat vent under it. It fits perfectly under the rear fold up seat with room to spare. I would buy it again in a heartbeat.

Pros: Excellent value for the buck. Rich sound.

Cons: Still trying to find any.

Great Lows!

Dan from Simi Valley, Cali on 12/26/2012

I put this Sub in my old Ranger pickup. Now this is a short cab truck & I'm 6 ft tall, so this is a small truck. Space is at a premium! I figured I would slide this under the passenger seat without actually taking a look. Well, I was pretty disappointed when I looked after I got it & the Explorer seats in the truck are about an inch off the floor. Not going to fit there. So the truck had small 3.5 speakers in plastic housings behind the seat I had planned on removing anyway, so I mounted the sub with some industrial velcro to the carpet on the back wall of the cab. Fits perfect! For a small space like a compact truck, this sub does a great job. The sound is a lot fuller & you can feel the base, even @ 70 on the freeway! The bass seems to hold up OK when I crank up the Megadeth. Even my 21 year old son is impressed.

Pros: Good price. Great package for a small space.

Cons: Could use more mounting options than the little strip of included velcro.

Good for inside vehicle

bikercr from Amherst, MA on 12/26/2012

Crutchfield Customer Review (What's this?)

Very nice build quality, really solid and pretty clean sounding. I would not recommend this, however, for trunk use. It's just not powerful enough. Ideal for inside passenger compartment, under a seat, etc. One other criticism: doesn't accomodate 8 AWG wiring. Posts are too small, but unit was matched with 8 ga wiring kit too large for it.

Pros: Very nice build quality and smooth sound when not too loud.

Cons: Not adequate for well insulated trunk use in passenger car.

Thump for Buck

Spieznutz from Alexandria, VA on 12/26/2012

Crutchfield Customer Review (What's this?)

Excellent powered sub. Incredible value, no technical complaints or sound complaints. This is an 8" sub, so please do not expect a earth shattering 12" sub. This is ideal for rounding out a quality stock system or mid grade compenent system. Perfectly completed premium sound system of my 2009 335i.

Pros: Price, high level inputs, wired-remote volume control. Light weight compact thump. Doesn't compromise weight or trunk space. High level inputs (no need to buy converter).

Cons: Must fabricate mounts if planning anything besides under the seat.

Sound Ordnance power sub

LMC from Fort Knox, KY on 12/25/2012

Crutchfield Customer Review (What's this?)

4.5; SO power sub simplifies the way a very nice car sound system should sound likes. We bought this product as a Christmas gift for our High School senior and our son is static with the sound. I even installed the unit by simply following the step-by-step instructions and is very simplistic. The unit fits below the second row seat and you will not even know is there unless you are looking for it. So pleased that I am thinking about ordering an additional unit for my own truck.

Pros: great sound at a great price. simple installation

Hope this ends up being a good purchase

Kobura70 from Orlando on 12/21/2012

Crutchfield Customer Review (What's this?)

I purchased this based on the review and article in the Crutchfield Catalog. Most items they have reviewed well have turned out to be good. I hope this will as well. I have had it for a few weeks, and haven't completed the installation, but I had a concern when I first opened the box, that I wanted to share. I will update this review once install is complete/ When I first opened the bod the remote control came out first, and immediately the remote felt like flimsy cheap plastic/ The back plate of the remote had also fallen off. Seems the glue that was holding didn't make it through shipping. This has me worried about other components within the powered sub itself that may shake lose once it's been pushing out sound for a while. As usual Crutchfield sent along a very nice installation kit, etc... I just hope this stands up to the test of time..



Much more than I expected in my '08 Ford Supercab

TerryN from New Orleans LA on 12/19/2012

Crutchfield Customer Review (What's this?)

I drive a 2008 Ford Supercab. I'm a 47 yo guy who used to have the latest Panasonic in-dash, Jet Sound EQ and Jensen Tri-Axials way way back in the day. I graduated to the Kenwoods, Punch, Alpines, etc etc in the 80's and other sundry items in years since. So I've always appreciated a somewhat decent system that did not break the bank. When I bought the Ford, which is honestly so damn well kept it amazes me, I wanted to up-gun the stereo (reliving my wasted youth). After installing a great Kenwood head unit and pairing that with Polk door speakers it was better, but not clean and clear at louder volume. Tthe incredible peeps at Crutchfield suggested the Alpine Power Pack to boost the HU power so we did that. Again, it got much better with increased horsepower for the Polks but no bottom end at all. In my cab there isnt alot of room for a sub whatsoever. So I looked at the compact Sound Ordnance B-8PT. I was skeptical but read the reviews like you're doing and was sold. Install was not difficult and after tweaking a bit I am truly blown away. I have to remember to turn it down at red lights lest I get the bad looks from fellow drivers. I listen to rock, country, a bit of pop, R&B, blues, almost everything except rap. So I dont need the rolling boom which this unit will not provide. What it does give you in spades in a tight punchy bass you will FEEL. And that is all I wanted. I LOVE IT.

Pros: Compact design, ease of installation, PRICE.

Cons: Nonestly, for the price, NONE.

jeep wrangler 1998

chrisA from grand rapids, mi on 12/18/2012

Crutchfield Customer Review (What's this?)

installed new speakers in my sons jeep for the holidays. put sound ordnance rounds in the sound bar and polk in the sides but the sound was all mids and highs, very tinny. not much you can do with such small spaces. so i called the crutchfield tech desk and they recommended this compact powered sub. wranglers have absolutely no space to put anything, so i was concerned, but after about an hour of installation (the free wiring kit was a lifesaver) i sat my son in the drivers seat and his smile said it all. the sound is a perfect match the mids and highs, the powered sub just puts the bottom in. with the remote dial control you can zone it right in. thx for the help.

Pros: size, power, ease of installation

Cons: none


Bruce from Mathews, VA on 12/17/2012

Crutchfield Customer Review (What's this?)

Great price for a lot of Bass. Mine came with an amp wiring kit which made the installation much easier. There are several adjustments on the B8PT and it took some time setting them and modifying the tuners options to get it sounding right.

Pros: Simple installation

Cons: Power terminals could be a little larger and have a protective cover.

Ford F150 Great Sound

ToddR from Weatherford, Tx on 12/13/2012

Crutchfield Customer Review (What's this?)

About a year ago I replaced my old stock radio and speakers with a nice Kenwood system but it just didn;t have much bass. I just put this powered sub under the back seat a few weeks ago and it sounds awesome. I have a 1998 supercab F150 that I've treated like a baby since it was I have a stereo system that sounds fantastic and makes my truck feel almost new again. The free installation kit makes it a good buy, the compact size makes it perfect for under the seat, and the added bass is sure to make just about any system sound great. Just buy it, you'll be happy with it!

Pros: Compact, free installation kit

Cons: I can't think of any

Just the right amount

Cons: Little better bang not so tinny

It does exactly what it is supposed to do

Freezing Dan from Hartford, CT on 12/11/2012

Crutchfield Customer Review (What's this?)

You are considering purchasing this unit because you want to add some low frequency bass to your mobile audio system but you DO NOT want to (or can not) fill up your trunk with a wall of giant speakers. Not you? Then keep looking. My previous vehicle was an Audi A6. I had a JL 10" sub in the trunk. It sounded fantastic and I didn't mind that it took up some limited cargo space. But in my new vehicle, a Toyota Highlander, I decided I did not want to sacrifice ANY space. Nor do I want a giant speaker box visible to every person on the street. So I opted to go without a sub. Ouch. I'm a "bass guy" - always have been. What to do? Well, there really was only one option - a compact sub. There are several compact subs on the market - take a look, Crutchfield has a great selection. But I wanted to position the sub UNDER my seat so that *I* can feel the bass. That narrowed my choices to only one or two units. And based on the reviews on this site I chose the Sound Ordnance. I had it professionally installed by a shop I trust. So here is my review: It does exactly what I had hoped it would do. It gave me the low end that was missing in my new system. Obviously I did not expect it to deliver the jaw-dropping bass of my previous system. And it doesn't. But it does add the low end that was missing and I am now a very happy "bass-head" again. I am thrilled with this purchase, at any price. Now factor in how much I paid for it and I'm even happier

Pros: Small. Fits under the driver's seat (in some cases). Does exactly what it's supposed to do - deliver the low-end frequencies like a champ

Cons: None. Really. I still can't believe how much bass this little thing delivers, and at such a low price. Unbelievable.

Depends on what your looking for

Garrett from IL on 12/11/2012

Crutchfield Customer Review (What's this?)

Like other reviews have stated, if your looking to wake the neighbors when you leave for work. This is not for you. However, if you are looking for some low ends to go with your factory speakers. I would recommend. It all depends on what you listen to. I listen to rock/rap and Dave Matthews band (which does not really fit into a genre imo) Different songs produce different sounds. One rock song might hit hard and make you think you have a 10 inch kicker behind you. Others just slightly fill in where factory door speakers lack. I have 2 8in Sony subs with a thousand watt amp I could have custom fit in this truck. But I was not looking for the window shaker, just more than what I had for a decent price. It's only been about 3 weeks, but I think this sub delivers. All depends on what sound you want. You want "big boom" Do not buy this. You want a little more low end sound without sacrifising room in your truck/car for a decent price. I would recommend

Pros: Price, Sound, Size

Cons: This unit has a auto turn on feature. Mine does not work and the manual is very vague. Maybe you have to be running the RCA cables for it to work? I tapped into the fuse panel to substitute for a lack of remote wire in a factory radio

B-8PT solid little sub

Brian T from Havana, FL on 12/10/2012

Crutchfield Customer Review (What's this?)

When I first hooked up this unit in my 2003 Rendezvous I thought, "this will never do." After using it for a few days though, it seems to have broken in nicely. I had to back off the rest of the system speakers to about the middle of the volume range and run the sub at full power and full volume on the receiver. This provides adequate response. See below.

Pros: Solid and compact enough to fit in the one place where it won't have to be moved in order to accommodate seating changes. The sound is tight. Can push lower bass guitar range without getting boomy.

Cons: Missing the bottom 20Hz. Thought about installing two, but I don't think that will expand the frequency range much.

Good clear bass

Fareed C from Washington, DC on 12/10/2012

Crutchfield Customer Review (What's this?)

I would recommend this self-powered sub-woofer to anyone who does not want to put a huge box in their trunk and ride around with their license plate flapping around and everything else shaking. This woofer is excellent and has enough power to create those perfect low notes that you might desire. I listen to a mixed array of music, ranging from classical, rock, acoustic, alternative, hip-hop, R&B, heavy metal, pop and everything else in between. And so far no issues with the bass on any of these genera but more pros than anything else. I enjoy my music much more than I used and would recommend these to anyone.

Pros: Clear bass, compact size, easy to install, settings

Cons: Might not be enough for attention grabbing, trunk rattling bass.


FassBaerie from Albuququerque NM on 12/10/2012

Crutchfield Customer Review (What's this?)

This thing is awesome - easy to install, great value, good sound (A surprising amount for such a small unit). I love that it's totally stealth under my seat.

Pros: ease of installation. Concealability

Cons: won't rattle the license plates off neighboring cars. Or is that a pro?

Sound OrdnanceT B-8PT

drjfjr from louisville, ky on 12/9/2012

Crutchfield Customer Review (What's this?)

I installed this unit in my Jeep Wrangler and it fills in what I feel has been missing in my system. I have an Alpine head unit and component speaker setup in the front with aftermarket speakers in the sound bar. frequency response in the upper ranges was great but low to lower midrange was severly lacking. This unit filled things out nicely.

Pros: easy to find a place to mount out of sight. remote adjustment is great


Just what I needed.

LSV from Newport, TN on 12/8/2012

Crutchfield Customer Review (What's this?)

The sound ordnance B-8PT was exactly what I was looking for to fulfill my low frequency needs in my crew cab pickup. The bass is clean and tight. I would definitely order this product again.

Pros: Compact size. Great price. Great sound.

Cons: The carpet in my vehicle is so fine that the supplied Velcro doesn't really grab properly.

Good sub

Erighty from Los Angeles, CA on 12/6/2012

Crutchfield Customer Review (What's this?)

Nice subwoofer for the price. If you're short on trunk space this thing is perfect. I have it in my Ford Focus hatchback and it produces enough bass to fill out the sound. I don't need to be rattling windows anymore (grown out of that), just something that will produce some punch for my system. I have aftermarket speakers, Alpine head unit and this sub. Works well.

Pros: Small/compact, punchy bass


So so subwoofer

Luke from El Paso, TX on 12/6/2012

Crutchfield Customer Review (What's this?)

Before I made the purchase I looked around for about a month comparing different subs in the same price range. I read a lot of good reviews for this sub and only a few that were bad. I bought it thinking it would GREATLY improve the sound system in my SUV but I can honestly say you can barely notice its there, unless you crank it up a bit and get pure rattling clacking noises from the sub. I'm not completely satisfied with my purchase and will probably end up returning it. FYI I had it professionaly installed. I WOULD NOT RECOMMEND THIS PRODUCT TO A FRIEND.

Pros: Cheap, small footprint.

Cons: As stated above.

Good Base for small package

ChrisP from Long Island NY on 12/4/2012

Crutchfield Customer Review (What's this?)

I needed more base after replacing the head unit and speakers in my WRX. I didn't want to take up trunk room so did research for good under seat power sub. I was nervous on the quality of sound but with my head unit and crossover selection, the sound is perfect. I like the remote base level adjustment especially when you have a passenger. Very Very nice product.

Pros: Great base for size, like the remote level

Cons: None

Big Sound From a Little Sub

BrewCityF150 from Milwaukee, WI on 12/3/2012

This is a great product! I have the B-8PT under the rear seat of my 2012 F150 Supercab. The F150 has 5x7/6x8 speakers on all 4 doors and the bass output is decent. I upgraded the door speakers to Infinity Reference and kept the stock HU. (I used the PAC AOEM-FRD24 to add pre-amp outputs so I didn't have to splice factory wires.) Adding this little powered sub to the equation filled in the low end perfectly! I was blown away by how much bass this little unit puts out. If you listen to hip-hop this might not be for you as the frequency range is 40-200Hz and you loose the chest shaking lows. This is a perfect solution for an in-cab sub if you listen to country music.

Pros: Great sound, small size, free amp wiring kit

Cons: Frequency only goes down to 40Hz

Sounds great

Brandon from Va on 12/1/2012

Crutchfield Customer Review (What's this?)

This is a pretty good powered sub. I installed this in a 08 Tacoma DC behind the driver side rear seat. It really brings out the lows that were missing from my stock speakers. I don't think it gives as much punch as my old Bazooka bass tubes from previous vehicles but it works perfect in the Tacoma. I still have some tweaking to do with the settings on the HU and sub to get optimal sound though. Component speakers in the front doors are next.

Pros: Crutchfield in general, quick shipping, great price, easy install

Cons: Non as of yet..

This unit is PERFECT for our 99 Jeep Wrangler! I connected it to a Kenwood Excelon KDC-X696 and it sounds awesome! If fits under the back seat like it was made just for it! It was exactly what I was looking for and I don't have to take up any of the already limited space in a Jeep.

Pros: Great sound for a small sub! Perfect when you have limited space! The adjustable control knob is a great feature as well.

Cons: 2 sided tape on control knob is weak. Fell right off. Going to have to figure out a new place to mount it.

perfect for money

Crutchfield Customer Review (What's this?)

Works great to add additional bass to factory unit. I have it in my trunk and it is fine. Would be better under my seat buy wont fit because of power seats

Pros: Great for the money. But if you are looking for booming bass not for you. Saves space

Cons: High level (speaker) inputs take a bit of volume to turn sub on...could always run remote power on but too lazy.

Sound Ordinance 8"

-brent from idaho on 11/26/2012

Crutchfield Customer Review (What's this?)

For the price-- the best I have found. The sound is actually stronger than I had imagined for its size. I have it under the back seat of my F150 crew cab. I replaced a 10" chopper series from Pyle. There is not comparison to the volume of the two; but the larger speaker in the Pyle does seem to mellow the harshness a bit better. Or-- I just haven't found the sweet spot in tuning the Sound Ordinance. The volume it produces is so much better I can lower the push on it and probably find the level I am looking for. Now remember this does not rattle my garage doors as I am age appropriate and don't do rap! -- teasing! I am older and appreciate the punch of bass and with out a SW it is hard to get it. I like this unit!!

Pros: value for power

Cons: none yet...

Good little sub

Zach from Trenton, NJ on 11/25/2012

Crutchfield Customer Review (What's this?)

I have to be honest, I almost sent this thing back, until i FINALLY got it tuned correctly. It was worth the extra time, and I'm sure glad i kept it. This little sub definitely won't rattle your brain but it does sound good. I have it installed in a 2011 silverado along with my pioneer x940bt and it definitely adds some nice low end i was lacking. Spend the time and tune this thing right, you wont regret it. Oh, i bought this thing and a couple days later it went on sale, and of course Crutchfield had no problem refunding me the difference. Crutchfield is the best!



Tips for a 2012 Toyota Tundra DC...

Rmplstlskn from Charlottesville, VA on 11/21/2012

I gave it 4 stars rather than 5 stars because the high level input (speaker signal) from my 2012 Toyota Tundra DC was not sufficient to turn on the subwoofer circuitry. I had to run a ACC-powered remote wire from the kickpanel wire harness to the subwoofer to turn the amp on when the key was in ACC or ON. Some tips for Tundra owners: Run the remote wire as stated above. This subwoofer fits PERFECTLY, and I do mean perfectly, tucked on it side, slid up behind the rear seat back IN THE MIDDLE section. The subwoofer is now at floor level and aimed to the front of the truck. Perfect location, no real loss of storage space... I soldered into the rear speaker wires on the B pillar (the pillar the rear door hinges are on). The wires are twisted together, so easy to locate. Drivers side is YELLOW (+) / BLACK (-) and passenger side is RED (+) / WHITE (-). You will have to cut some electrical tape to get enough wire to work with. The sills and B pillar trim pull off, and you will have to remove the drivers seal belt anchor bolt (13mm).

Pros: Decent subwoofer for its small size and good price. Fits perfectly in a Tundra DC. Sounds good with a much needed thump.

Cons: High level inputs are not sensitive enough to turn sub on from my Toyota Tundra rear speaker signal, had to run a seperate remote wire. Instructions could be more detailed and give more info on how to set the dials right.

Good for decent bass

Anthony from Morrow, GA on 11/20/2012

Crutchfield Customer Review (What's this?)

So far I have been very impressed with this speaker. I have it installed under the rear seat in my F150 and it provided a decent amount of low end to my music. I literally listen to every genre of music and this speaker improved the sound for all of them. If you are looking to shake the windows and upset the neighbors this is not for you. However, if you've grown up and are just looking for some good bass at a good price that is easy to install, I highly recommend this.

Pros: completes an aftermarket system adding good low end sound for a great price

Cons: bass won't be as deep as you will get in a 10" or 12" sub but duh, it's 8"...if you want deeper bass get a bigger sub.

Great Value; Poor Performance.

Ian from Wichita, KS on 11/19/2012

Crutchfield Customer Review (What's this?)

This is a great product and I've used it for about 10 months with absolutely zero problems in my 2011 Ford Focus... The build quality is better than average and makes this product a fantastic value. It fits great under the passenger seat of my Focus but it is just an inch too long and encroaches on rear seat foot room. The installation hardware included makes things super easy to get installed and the auto-on with high-level inputs made this the perfect addition for my stock sound system. I have SYNC so I needed to be able to use my stock head unit. I would've given a 4 star rating but the lack of response below 100hz is such a glaring fault I can't justify recommending the product to anyone else. I wanted a sub-woofer, not a dud-woofer!

Pros: -Easy almost literal plug-n-play installation. -Small form factor means stealthy install away from prying eyes. -Low distortion speaker -Super value from Crutchfield

Cons: -This subwoofer simply does not hit frequencies below 100hz. I've been extremely disappointed in the range this product offers. From 100-250hz it sounds great but that's not what I want from a subwoofer! -This product creates a lot of heat. Be very careful where you mount it and make sure it has room to breathe. Keep it away from adhesives and other sensitive materials.

David from Deland, FL on 11/12/2012

Crutchfield Customer Review (What's this?)

I've always had big subs that consume massive amounts of space in my vehicles. As I get older, I still want great sound but am no longer willing to sacrifice space. I place tools and gear under the back seat of my truck and figured it just wouldn't be a possible to put a sub in. However, this is the smallest powered sub package I have ever seen. It is basically the size and thickness of a large text book. It can fit just about anywhere in any car. You are not going to boom down the street but it does a great job at doing what it was designed to do. Your music will sound complete/full. I would recommend this to anyone looking to upgrade the low end of their system without taking-up much space or draining the electrical system (or wallet).

Pros: Size, ease of install, price, output for size is impressive

Cons: It is what it is...don't expect it to blur your vision.

Love it!

Smurf from Clarksville, IN on 11/5/2012

Crutchfield Customer Review (What's this?)

I really do love this speaker. I have a small car (Nissan 370z) and this add plenty of bass for me. I listen to a lot of jazz and blues and it hits beautifully for that style of music. If you're wanting to vibrate the license plate off of your car, this probably isn't for you, but if you value your hearing but want a little extra, this is a perfect unit. It probably also depends on the type of vehicle that you have. Since mine is small and I have the speaker directly behind the driver's seat, it's great.

Pros: Spacesaver. Sturdy construction. Great sound. Great "bang for the buck".


OK product

Jamen from Dublin, CA on 11/5/2012

Crutchfield Customer Review (What's this?)

Plays something like above 100hz pretty well, but this 8" woofer definitely will not give you any deep or high quality lows. Overall, adds a good amount to my very small car, but I wouldn't recommend it if you're expecting high quality, deep bass, or if you have a larger car/truck.



sound ord b-8pt

john from Bend, oregon on 10/30/2012

Crutchfield Customer Review (What's this?)

The unit was not what I expected. The subwoofer is nowhere near the quality I expected based upon the technicians advice. I does help with the bass, but nowhere near the quality of the kicker 8 inch subwoofer and separate amp. I wanted more control than this unit allows. It meets the overall needs of my Ford f350 and is adequate but not superior.

Pros: small, fits under the front seat, helps fill the bass need.

Cons: Lacks the response of similar units that are non-powered subwoofers with an decent amp

Good for added support

RogerM from Baldwinsville,NY on 10/28/2012

Crutchfield Customer Review (What's this?)

Was looking for something to give some boost to the lower notes of mostly classical/traditional jazz music to enable me to reduce base boost on the smallish door speakers (replacements) in a RAV4, which would improve the mid-range on the door speakers. Took some control tweaking but now works quite well, essentially a seamless part of the sound system. Not the product if you're a yute hoping to shatter the windows in the vehicle next to you ... Note: I had it professionally installed & had to have them rewire to go on with the ignition (with an off switch), the alternative automatic turn on with the radio would only kick it on if I had the volume turned to blasting

Pros: Compact size fit in a relatively unneeded space, provides enough added oomph to counter road, other noise and reduce need to boost standard speakers/less distortion.

Cons: Would not turn on through radio except at extremely loud levels, had to rewire to turn on with ignition switch, less preferable, you'll need a switch to avoid having it running if the radio is not on. Doesn't get much lower base than the car speakers if that's what you're looking for, mostly helps in the 70-125 range.

So that's what was missing

2012 Nissan Frontier King Cab... Upgraded head unit to Pioneer AVH-p2400bt and kept the factory speakers in place. I had no bottom end and barely any mid range. The Sound Ordnance B-8pt added an incredible depth and sound! It's unbelievable that this tiny flat sub can produce bass you can hear and feel. Makes my factory speakers sound sooooo much better. I am going to upgrade my factory speakers with Sound Ordnance speakers... It can only get better!

Pros: Big sound, small enclosure

Cons: unless you are entering SPL competitions, there are none!

To be honest when i took the sub out of the box and seen how small the sub was i thought this is'nt gonna be worth putting in.However it did fit perfectly under the extended cab seat of my 05 F-150. So after putting the sub in it was very impressive for such a small pakage, even hits hard !!!! Love it.. i did have to phase the sub using the control on the side for it to sound right under the seat.If your looking for a good sub to fill in the bass notes you have been missing then this is for you and the remote control knob will alow you to tune the sub for different songs and volume levels easily while driving down the road.... ohhh and also you get a real nice amp wiring kit for free when you order one right now.

Pros: fit under rear seat. good bass response,built in amp,free wiring kit,remote level control, and strong enclosure.

Cons: only comes with velcro to mount box with. will need to make a bracket to keep it from sliding and shaking

Just what I was looking for

Crutchfield Customer Review (What's this?)

I bought this to add some bass to my F150 Supercrew. My first Idea was to get a Thunderform but after reading the reviews and speaking to a Crutchfield advisor I decided to go with the B-8PT. This little thing fit my need perfectly. I listen to mostly jazz some classical and some gospel music so I don't need to rattle my windows like I did when I was 18 years old. It slid snugly in the compartment behind the back seat perfectly without any hardware. I have't tweaked with the settings yet but I can tell that it has more than enough bass to supplement my system. I can adjust the level, crossover and phase from my Kenwood head unit so I'm sure I will be able to get it just right. The install was straight forward and I was able to get the very high quality wire kit for free with the purchase. Connectors for the ends of the wires that go into the amp would have been nice but that wasn't a big deal.

Pros: Great sound in a small package. Doesn't need alot of space to install. Free wire kit with purchase

Cons: Haven't found any yet

great buy

I put Boston Acoustics seperates along with a BA amp in the back of my super duty crew cab and needed more bass. This box really does the job! I am blown away by what a difference it makes. Great tight bass was just what i wanted. Easy install and fits great under the seat.


Cons: no way to tie it down. You have to figure something out yourself

Perfect for small spaces

Bartman from Memphis TN on 10/7/2012

Crutchfield Customer Review (What's this?)

I paired the B-8PT with a Clarion CX-501 and Polk Audio speakers in the factory openings of my 2001 Nissan Frontier. The sub rounds out the bottom end nicely supplying bass that can't be reproduced even with the Polk speakers because of their size. The sub tucked nicely behind the rear seat of the crew cab without any modification to the truck body.

Pros: Clean quality bass. Just right amounts for all types of music. Fits very nicely in small spaces. Won't knock your teeth lose or rattle the doors but still shakes the mirrors.

Cons: The free install kit requires a trip to the auto parts store to get the right electrical connectors to terminate the connections at the sub.

Such an easy installation, came with free install kit!! Product sounds good, not overwhelming. Good quality bass and sound even in my full size four door F-150.

Pros: Good quality, ease of use, ease of install

Cons: Can distort a little at high volumes, but I can control that with tweaking the Gain control.

Very good for what it's designed for

Greg from San Diego, CA on 9/28/2012

Crutchfield Customer Review (What's this?)

Great sub and great value overall, but you really need to know what you want out of your sub. I got this sub for my 2007 Nissan Altima and installed it in the trunk. I wanted something I could turn up and rock out when driving alone, to and from work, and I could turn it down with the kids in the back. This is a small, sealed enclosure sub, which rounds out and fills the bottom of the sound, it does not move enough air (at least from where I installed it in the trunk) to give that BOOM or THUMP that a ported or bandpass enclosure provides (which is what I had in the past).

Pros: Perfect size which give you many placement options, easy to install and set up. The enclosed remote level knob is great for adding on to factory stereos, but not needed on most aftermarket head units because of the built in subwoofer controls.

Cons: Not for Customers looking for the BOOM that you would get from a ported sub box, which was what I was used to in the past. No mounting hardware - only velcro straps which do a good job on the trunk carpet, but it doesn't allow the sub use brace and vibrate the trunk which would improve the sound.

Excellent Product

Greg G from Aurora, CO on 9/28/2012

This is one excellent little subwoofer. I had it professionally installed in the back of my 1992 Honda Civic VX hatchback. The B-8PT is perfect for my needs: smooth, tight bass, but not overwhelming. It blends well with my 6 1/2" Infinity door speakers (the VX isn't equipped for rear speakers). My old sub box took up half the hatch area, and this little gem gave me a lot more usable space. It has worked perfectly for me for the one year + I've had it. I listen to a wide range of music, from classic rock to techno and even some classical and new age such as Enya, so my sub has to be versatile. The B-8PT handles everything without a problem. The only issue I had with it was the sub level control unit did not work after the installation-not a problem, since I use the sub control on my Dual head unit instead.

Pros: Compact size, smooth, tight bass, reliability. Excellent, cabin-filling sound.

Cons: Sub level control doesn't work. Easily rectified by using head unit sub control.

Awesome Product!

Rey S. from Fort Worth, TX on 9/27/2012

Crutchfield Customer Review (What's this?)

Was looking for something that would at least keep my little Ford Ranger from sounding like a tin can. I purchased the B-8PT and had a local installer put it in for me. He told me when he first saw it, that these type of subs really don't do much for the sound, however once he installed it, he came back to me and said he was totally blown away by the quality of sound from the little unit. I can honestly say that I was expecting and would have settled for much less, but in turn, now I have one rockin' system in my Ford Ranger!! WOW...It totally rocks everything from Jazz, Blues, Rock, & Country!! This baby is a MUST for all those with little room for a standard sub and at a price that can't be beat!

Pros: Slim Profile, easy connections, works vertical as well as horizontal, durable finish, great price with awesome sound!

Cons: None that I can see.

Crutchfield Customer Review (What's this?)

Great product for the money. Own a Jeep Wrangler. Had a sub installed in rear section and had all speakers upgraded. But there was something missing in the middle range. This sub fit the ticket. Added just enough bass to tie the front and the rear together. Great product.

Pros: small enough to fit under front seat. Easy to have installed.


You can tell its cheap

Spiderman201 from Richmond, MN on 9/25/2012

Crutchfield Customer Review (What's this?)

bass is marginal improvement over factory speakers, even with the difference of sound with a new receiver being 1 to 100. To top it off, my wife & I switch cars periodically, I am back in the one with the powered subwoofer, and even though the power LED works, the connections are secure, etc, there is no sound coming from it. That was the main neg review of it that it was poor quality, and I guess I made a fool's investment for it.

Pros: small, fits under seat

Cons: cheap product, sound isn't that impressive (compared to quality in door speakers or especially real subwoofers).

Not too Bad

Cory from Logan UT on 9/24/2012

Crutchfield Customer Review (What's this?)

I received this and it was super easy to install in my GMC Sonoma. The Bass compared to just the speakers was pretty good. It didn't fit under my seat, but it is rather small so it fits about anywhere else. It's nothing like a box sub but for what it is meant for I would recommend it. However there was a price break on the Infinity Bass Link which made it the same price as this so I returned this one and got the Infinity Bass link, and although much bigger, the sound difference was unreal. I would recommend this to someone with just a small cab or so.

Pros: Small, easy to install

Cons: Price is a bit high for what it is.

All I can say is "wow"!!

Amp from Syracuse, NY on 9/22/2012

Crutchfield Customer Review (What's this?)

Bought this subwoofer after replacing the four speakers in my Kia forte with Polk DB's. The Polks just did not supply the bass that I wanted for a well balanced sound (typical of Polk, but I love everything else about them). I kept the stock head unit, thus making it difficult to add an amp... So on recommendation from Crutchfield, I went with this flat powered subwoofer to go under my seat... And wow, I'm very glad I did!! It's more bass than I expected... and along with the mids and highs from the Polks it sounds perfect. If your looking for more bass, and want to do it the easy way, go for this speaker + Installation is a breeze !!

Pros: Great bass plus adjustments for it...easy installation...remote for level of bass...hides perfect under front seat

Cons: Seems to take about 1 minute to power up so you can hear it (I can live with that) for the sound and price !!

Big Sound in Small Package

Dustin from Lake Charles, LA on 9/22/2012

Crutchfield Customer Review (What's this?)

I was looking to upgrade my sound with a little more low end but not a huge footprint and this was what the doctor ordered. The B-8PT fits under my bucket seat in my Mazda Tribute (like a Ford Escape) and gives me a thump I can feel. I am still playing with the phase and low pass filter controls to get a clean sound, but so far this has made a big difference. Remember, this is not made to violate the "sound ordinance", but if your short on space, this is a great product. Cons- The diagram was not very helpful. I had to get some help on installation

Pros: Meets description perfectly. Good addition to beef up a stock system.

Cons: Setup diagram not helpful.

In a world where you can't get any subwoofer for no less than 300 hundred. 199.00 ymmmmm. ,but I digress. As long as you understand what to expect you will more than pleased. Fits perfect under the passsenger seat of my 2011 Prius. Filled out the low end quit nice. Very happy with it and would recommend. Even the place that installed it was surprised since they never heard of the brand,but once they heard it they where also impressed.

Pros: Price and sound

2005 jeep wrangler unlimited 2 door lwb Head Unit Alpine-CDE-133BT Alpine S series 4x6 front 5.25 sound bar. I installed the head unit and speakers last week full well knowing that it was going to lack base. I put all of the speakers in foam baffles and vented the backs. Stuffed the sound bars with poly fill from a tired pillow. Packed poly fill around the 4x6 and wow it sounded good. Really good even had a bit of bass and the sound bars did not rattle. It still needed rich full bass so i started searching for a sub to toss in the back but had no interest in a big box that was visible. Before i ordered The Sound-Ordnance-B-8PT I tested the fit with a box built to the specs provided by Crutchfield but built a bit oversize. Long story short it arived today and i rushed home from work to test the fit. This was made for the TJ wrangler, fits under the rear seat like a glove. It is invisible to thiefs and pretty well protected from the elements with the seat covering it i will take it off road. It sounds great out of the box but I will play with the controls tmrw. If you are looking for a compact sub for your wragler this is a no brainer.

Crutchfield Customer Review (What's this?)

I was excited about getting this sub. However once it came to mounting it I was very disappointed. There was nothing included to mount it with nor were there any mounting holes or locations to mount this sub. I had to fabricate little "L" shaped brackets to secure it to my the vehicle. As this is a "SUB" you don't want it just laying under the seat as if its not secured it will vibrate when in operation. just took to much time to install and isolate to eliminate vibrations. I was going to go with the RetroSound SUB-8100 and would recommend that sub if looking at this one as it comes with 4 mounting tabs. I will be purchasing that sub for my next installation. Sound is great if this sub had some way of mounting it securely with you having to engineer a solution I would have rated it higher. The RetroSound SUB-8100 would be my suggestion.

Pros: Great quality, sold sound

Cons: installation of the product wasn't even though of from the mfg. I received 1 screw 2 peaces of Velcro that were the same & 2 zip ties. Not really sure how they intended you to mount this amp/sub.

It is so small it fits underneath your seat, and I guess that is why it can't produce any real bass. It is loud but not a real thump. You won't get that deep rich sound.

Pros: compact

Cons: loud but can't reproduce good base..

Very easy to hook up with the FREE sub wiring kit included Really brings up the bass in the vehicle Not overpowering but has a great bass sound like you would want with rock or heavy metal music Not just the BOOM bass of rap music, if you want that then this sub probably is not for you

Pros: Great sound, easy to hook up, fits under the back seat of my Chevy Colorado, everything I hoped for.

Cons: None yet

Sound Ordnance for the Jeep JK

Clay from Frederick, MD on 9/2/2012

Crutchfield Customer Review (What's this?)

Ok all, I spent one year researching how to get perfect sound in my 2011 Jeep JK 4 Door. I wanted a jukebox on wheels but not a thumper. I installed all Pioneer in the head unit, four 300 watt three ways and an 800 watt mini amp under the passenger seat to power them. Then I researched a sub to hit the perfect 3-D sound. Sound Ordnance more than delivered. This thing fit neatly under my back seat and comes with a bass dial to turn the bass up and down depending on what you are listening to. I listen to EVERYTHING, I mean everything and this powered sub delivers on every level. You control the bass level right from your seat thanks to the bass dial which has plenty of cord to be velcro'ed near your drivers seat. Mine is neatly hidden in the glove compartment to keep it concealed. Anyway, in short, I'm 40 years old and knew what I was looking for, if you want bass, in a small package, but aren't looking for competition level (although my neighbors now know when I am coming home) this is the one stop shop. Look at the reviews, I guarantee you will not be disappointed. I DO NOT work for Sound Ordnance and rarely review, but when a prop is due....... Anyway, Jeep Wrangler owners, yes I'm partial, this is your sub.

Pros: Everything!

Cons: Absolutely none.

Thumbs down!

Spanky04 from Vienna, OH on 9/2/2012

Crutchfield Customer Review (What's this?)

This subwoofer did not have the deep rich bass that I was looking for. Very poor sound performance! I woiuld not recommend this to anyone who is a real deep bass lover. Very expensive for what you actually get, not worth the money in my opinion. I returned it and bought a Polk 8" boxed subwoofer, which will knock your socks off and costs half the price.

Pros: small and compact

Cons: no deep bass tones, hardly any bass at all, very expensive

Excellent Base

jshepherd61 from Denver, CO on 8/24/2012

Crutchfield Customer Review (What's this?)

Wow! Bought this because Porsche doesn't give much room in the Boxster for speakers or a sub and the factory speakers and sub doesn't even sound as good as my iPod. I mounted this behind the passenger seat, I lost 3/4" of seat travel but still plenty of room. I was very surprised at the base it put out even with the top down. I control the bass with my deck and only have it about 1/2 way and it rattles the windows and the trim in the car. I listen to everything from Celtic music to Niki Manaj to Toby Keith. For the price it's a must buy.

Pros: compact, very controllable, ease of installation

Cons: Still a powered sub and not a custom

Amazing sound, clean install!

MichaelL from Chattanooga, TN on 8/11/2012

Crutchfield Customer Review (What's this?)

I've installed this unit twice now, and both times it has made a WORLD of difference. I installed it along with a new HU in a '01 4Runner and then worked into a factory HU in a '07 Civic Hybrid. It's easier to install with a new HU, but it made my factory system sound so much better! If you're looking for car-rattling, trunk space consuming, high school bass head soundgasm, this is not the unit for you. If you want an invisible, simple, high quality unit that puts out an amazing amount of deep bass, you've found the one! I wouldn't hesitate to purchase this unit a 3rd time.

Pros: Clear sound More than enough base for anyone 18+ Clean (invisible) Installation Dependable Makes your factory system sound SO much better!!!

Cons: If you tie it into your factory system (by tapping into speakers), the auto turn-on feature isn't sensitive enough. The unit won't turn on until you've turned the volume way up, and will cut out after you turn the volume down. Solution? Use a fuse tap to tie your remote turn-on cable into your acc1/radio fuse or wiper fuse (consult with customer service if you need help, they're amazingly helpful), and voila! Dependable, amazing, deep bass every time.

Great Little Sub

Steve from Warrenton, VA on 8/1/2012

Crutchfield Customer Review (What's this?)

Have had this sub for almost a year and this is the first time I have ever reviewed any product on line. I love this thing. I put it in a 2011 Subaru Forester and it was exactly what the facory system needed to give me some nice, undistorted low end. I did the line level hook-up (i.e. I hooked into the factory speaker wires). The device the rep sold me to hook into those wires is awesome. IMPORTANT!! If you do a hook-up like this, you need to run the little blue wire included with the wiring kit into your fuse box so that the sub powers up when you turn the vehicle on. I've seen other posts where people complained that the sub would cut off at low levels or not come on at all. For line level inputs, this is the solution. If you are looking for nice, musical low end, I would recommend this sub. As tons of people have said, this sub will not rattle your windows, but it is perfect for me. It fit under my front seat and I have not had any problems over the past year.

Pros: Good, clean bass, relatively easy installation, fits under my front seat.

Cons: None

Disable and not very well off, as far as money Eddie 3289 advised me the way to go would be this compact 8" power sub-woofer for my car. Told him what I drive and he assured me would be the easiest. Told me how it would hook up and within a day placed my order. With my neighbor doing the instaliation sounds better the I ever expected. Local shop wanted $600.00 to fix me up, this route $199.00 for unit plus $20.00 for speaker wire and to top it off installation gear was free with this unit. Best buy I've made in years. Looking to upgrade my speakers and even my factory radio now nothing fancy but better than what I have.

Pros: Simple easy hook up, enough power (in a way over powered) because of so many types of music, great size, fits under seat very well, installation gear free, remote works great depending on styles of music. Instructions clear.

Cons: Not buying this a long time ago.

Crutchfield Customer Review (What's this?)

This is my 2nd Sound Ordance B-8PT. Have had one in my F-350 Crummy for 3+ years now and decided on another to add to my Artic Fox 990 camper. All in all this unit provides the extra thump that was missing in both rigs. It will by no means offer the same bass response as bigger pemanent costume made boxes but you will enjoy the added lows that this units provides.

Pros: small package, big of speaker because of the construction of the way to poke a hole in the speaker. Design and over all looks...stout unit which offers great protection...once installed dont have to worry about something coming into contant with it possibly ruining the speaker

Cons: Mounting options very limited. A flimsey peice of 1/2" x 4" velcro is all that is supplied. If this unit is to be placed anywhere other than under a seat sitting horizontal you are going to have to get creative and figure out how to attach this unit to their vehicle.... my work around was large pieces of 2" x 10" H/D velcro mounted to the underside of the unit and then attched to the sufface of the mounting location.

Crutchfield Customer Review (What's this?)

After upgrading the speeakers (ARC) and added a 500 watt Alpine 4 channel amp to the factory Rockford Fosgate system on my 09 Nissan Xterra, the OEM subwoofer under the seat did not match the power or clarity of the new ARC speakers and Alpine amp. After reading all the reviews on, I decided to get the Sound OrdnanceT B-8PT to replace the OEM sub under the seat. All I have to say is "WOW!" The difference between the OEM Rockford Fosgate Sub and this one is night and day. I listen to everything from Andre Bocelli, Garth Brooks, Miles Davis, Bon Jovi, Pitbull, and Dr. DRE. Once the B-8PT was installed, it completed the upgrade. Clear, and tight base that does not distort. Excellent!

Pros: Clear Covers a nice range of low (not super low) frequencies that enhances music versus overpowers it Stealthy Powerful

Cons: None

Crutchfield Customer Review (What's this?)

Recently added Alpine Head unit and 4 Polk speakers in my 2008 Ford F250 Extended Cab truck. Sound is a major improvement over stock. Made the choice to add a sub, and chose the Ordnance B-8PT based on customer reviews. The unit takes very little under the rear seat, and adds depth to the system. I can turn down the bass to the door speakers and up on the sub, to give me the improvement I desire. Bass heads will need something more. Mature drivers will enjoy the balance this sub provides. Overall - a very good buy and good value. Porting the unit would most likely reduce the boxy sound on some tracks. Offering a twin - stackable B-8PT system would be very attractive.

Crutchfield Customer Review (What's this?)

an easy install in my 84 S-10 4x4 , I used the some high density shipping foam as a backer and just sheet metal screwed the unit to the back of the cab panel behind the drivers seat. It left plenty of room behind the seat back and I can still put seat all the way back if needed. Nice thump is felt through the seat back at only 1/3 setting. Highly recommend the level control as some songs are over-boosted these days. sound really fills out the range with the infinity speakers I installed at the same time. As others have said not for the car show curcuit, but definenatly worth the money

Pros: small yet powerful tight bass, fits well in odd locations. also seems very shock durable

Cons: somewhat cheesy level control but have not had problems due to screwing control to bottom of dash ,don't rely on mounting tape supplied

Great little addition

JK from San Diego, CA on 7/10/2012

Crutchfield Customer Review (What's this?)

I bought this knowing that I wasn't going to get that super low 20-30Hz bass that larger enclosures can give you. All I wanted was to take some of the stress away from my main speakers and have this little guy take over bass duties. For this purpose, it is a win! After installation, I have it dialed in with a 63Hz crossover point from my head unit. The B-8PT will only cross over as low as 80Hz. The bass boost is off, as I do all EQing from the head unit. I have my EQ set flat with a small dip at 100Hz, since I had a hump in that range. If you're like me and your days of LOUD stereos are over (ie. wife and baby), then this will fit the bill. I have it installed in a 2012 Subaru Outback and it fits perfectly under the passenger seat as long as you trim away about 1/2" of one the floor vents, which can be easily done with a utility knife.

Pros: Stealthy installation options. Relatively high power for this category. Good price.

Cons: None for this type of subwoofer.

If you have a SUV and are going to locate this in the cargo area you may reconsider this and get the JBL GT-Bass Pro12. The Sound Ordnance B-8PT is perfectly sized and sounds extremely nice except when on the freeway with the windows down. It just gets drowned out completely. Again it's a nice product but depending on install location and the type of ride you have you may be a lil disappointed once traffic noise comes into play or even if you crank your non stock system. Crutchfield, as usual are outstanding and I was able to return mine without a hiccup.

Pros: small & convenient. easy to hook up. overall excellent product if the power meets your needs.

Cons: drowns out in SUV on the freeway.

I just installed the Sound Ordnance B-8pt, Polk Audio 651s,in the front door, Polk Audio 461p in the rear door and a Alpine 75 Watt 4 Channel into a 2002 Silverado. I used the same HU because i wanted everything to look stock. All i can say is WOW, the sound is incredible. I listen to classic rock and some country. The music is crystal clear, and the bass has just enough boom. You can really feel the bass guitar and drums. It's not the kind of bass to rattle the store windows, it's just enough to feel the bass. Hey i'm 55, i don't need the kind of bass to rattle the windows. Everything fits perfect. With me keeping the stock HU the Alpine handles all the power.All the stock HU does is drive the CD and Fm.I didn't have to cut any door panels,the sub fit under the rear passenger seat, and the Alpine fit on the hump under the rear seat. That left the left side for storage, tie downs etc.

Pros: Great price and fit.

Cons: Non

Nice Sounding Bass

Alex from WI on 6/30/2012

Crutchfield Customer Review (What's this?)

The B-8PT is a nice little setup. It sounds great under the back seat of my truck (2011 Chevrolet Silverado crew cab). I didn't need window shaking bass and even with a four door truck, space is still an issue. The B-8PT isn't the 2 10's I had in my previous truck, but I didn't expect (or want) it to be. I haven't turned it all the way up yet, but even at 1/2-3/4 it puts out quite a bit of bass. I put Pioneer TS-A1674R speakers in my doors and added this sub to my factory head unit and it's a night and day difference. This sub seems like a great choice for anyone who just wants to add some punch to their music.

Pros: -Price -Compact -Great bass

Cons: -I had a little trouble hooking up the 10 gauge power and ground wires to the B-8PT. It seems the connections on the B-8PT could have been larger, but nothing major.

An inpressive little unit

Crutchfield Customer Review (What's this?)

If you are looking to turn heads with rattling fenders, this is not the unit for you. If you want a reasoanble, well shaped, full round sound in your passenger compartment give this unit a serious look. I bought this and a Kenwood DNX 6999 which I planned to install myself. Time constraints persaused me to hire a local car audio house to handle the intallation (along with a remote starter) They were quite impressed with this unit. They called me back to get more info about it.

Pros: Excellent sound and presense for an underseat sub. It provides just enough thump to overcome road noise, while fitting underseat.

Cons: Cons? I cant fault it for missing super low low notes, given it's size, when 99% of music benifits greatly. Could be cheaper. Could come with Doritos. But seriously? None.

Crutchfield Customer Review (What's this?)

I am impressed by the improvement that this unit brought to my 2012 Honda Civic. It fits perfectly under my front passenger seat. Easy install, and the adjustable level remote is cool. I read the reviews before the purchase and they were accurate.



Plenty of bass for a jeep wrangler

Rich from Geneva, Il on 6/27/2012

Crutchfield Customer Review (What's this?)

Kenwood head unit alpine amp and polk speakers left me needing the low end to round out the system and the sound ordnance sub has done the job for me. Didnt seem like a good fit under the front seats and wouldnt go under rear but fit inside the hide a trunk great and still has plenty a sound, no reason for a bigger sub for my tastes. Rock, Reggae, Blues, Country its all sounding great now.

Pros: Great sound for its size and price when space is limited

Cons: Havent found any

Great Sound

Crutchfield customer from Houston, TX on 6/26/2012

Crutchfield Customer Review (What's this?)

What a great product! I put this in my wife's highlander and we were both surprised about how much bass it put out. Not only does it put out a lot of bass it has a great sound. It was also the perfect size. I can still let my seats down and lift the compartment in the back without moving the device.



Bass brings out the Depth in music/speech

LarryC from Los Angeles, CA on 6/23/2012

Crutchfield Customer Review (What's this?)

In a 2002 Camaro Z28 there is not a lot of room to install a bass unit if you want to be able to get groceries now and then. This fits under the passenger seat (a little into the rear footwell but not over much. (nobody rides back there anyway.) There is enough bass to fill the car and bring out the depth in music. I also listen to a lot of lectures on trips and find the vocal sound quality much improved. Great value!

Pros: Good bass. Comparative small size Good control over the sound.

Cons: Haven't found them yet.

Good deal

Kyle from Belfast, Maine on 6/23/2012

Crutchfield Customer Review (What's this?)

Vehicle: 2000 F150 Location: Under Middle back seat Time to install: (My first time, 3.5 hours) Very good product. Wish that the manuals were a bit more detailed on sub controls. I put the remote analog control right on the lower dash, and it is so easy to control with different music or when my kids are in the truck.

Pros: Analog sub control, size of sub, smooth sound.

Cons: Manual details

This little sub is insane!

Metal4Life from Danbury, CT on 6/18/2012

Crutchfield Customer Review (What's this?)

I purchased this sub to add to a new system in my truck. I have an Alpine 50 x 4 head unit, Alpine 6 x 9's in the front and Kicker 6 1/2's in the rear. Really not a crazy system, but I gotta tell you, after this sub was installed it dramatically improved the overall sound. The guy that installed the sub wasn't impressed when he opened the box but after he installed it he was amazed! I am very happy with this purchase. Crutchfield customer service was superb, Colt made sure I ordered everything I needed for the install and followed up to make sure everything was going smooth. Couldn't be happier with the Sound Ordinance sub or Crutchfield!

Pros: Nice compact size, awesome bass output, low cost

Cons: I can't think of any at this point.


Derral from Vancouver, WA on 6/18/2012

Crutchfield Customer Review (What's this?)

This is one of those few things in life you buy and are surprised that it surpasses your expectations. I purchased this for my Dakota regular cab truck and was blown away by how great the bass was. Music in the truck is a bunch of fun to listen to now. I only have it set at 1/4 and it is amazing. It has way more punch than I am able to use but it's awesome knowing it's there if I want it. I am way passed satisfied with this and it's a great bang for the buck.

Pros: Amazing power in a small package.

Cons: Would really be nice to have a mounting bracket of some sort but it's not hard to fabricate one.

Works as advertised

DB from NYC Area on 6/11/2012

Crutchfield Customer Review (What's this?)

Bought this to go under the seat in my 1995 Jeep Wrangler and it fits well right under the driver seat. Nice to have the bass included with my stereo system.

Pros: I am by no means an audiophile but the unit sounds good with the JVC head unit and the POLK marine grade speakers in the dash and on the floor.

Cons: The EFX 10 gauge wiring kit that I bought include spade connectors for 14 guage wires so I needed to run out during install to get proper connectors for the 10ga. power and ground. I know Crutchfield isnt responsible for that but it was a PITA that added an hour to the install.

Great addition to the system

Brad from Paulina, La. on 6/7/2012

Crutchfield Customer Review (What's this?)

I wanted to add just a little bass to the system I have and not spend a lot of money. This was the perfect fit for my needs. Just the right amount of Bass for me. If you want heart pounding Bass than you will want something different. But if you want just enough to make the vehicle sound full than this is what you want. I have it in my truck just under the back seat and it sound very good. I have Polk in the doors and together it sounds very nice. I would recommend this product to anyone.

Pros: Small for tight spaces. Priced right and the free install kit was nice to.

Cons: None

Sound OrdnanceT B-8PT

Scott F from Cincinnati, Ohio on 6/5/2012

I continue to be impressed with this subwoofer. I purchased it to round out the sound of a stock system in a Ford Focus. It does an amazing job given it's size and limited power in filling in the lows that the stock stereo can't provide. Like others have noted, it did take me some time to "dial it in" and get the sound just right. The controls are there for a reason - use them! I initially thought it really boomy and hollow but realized after a time that I had it turned up too high. I've also noticed that it has started sounded better after a few weeks. Overall, very happy with it and would do it again!

Pros: Small size

Cons: Turning it on via the speaker level inputs instead of the remote wire (my stock stereo doesn't provide this line) requires the radio to be turned up pretty loud.

Major sound improvement

PKRO from Lancaster, PA on 6/2/2012

Crutchfield Customer Review (What's this?)

Really fills out the deep bass part of the sound spectrum, this sub moved my car audio system performance from barely OK to pretty good.

Pros: 1) Surprisingly good bass in a small package. 2) Fairly versatile in terms of being able to adjust the bass sound to personal taste. 3) Remote level control. 4) Totally disappears underneath the passenger seat of my Honda Civic.

Cons: 1) Don't buy this if your goal in life is to annoy others with your sound system. 2) Low pass filter is 18 dB/octave. While most people prefer steep filters like this, a 6 dB / octave slope would have worked better in my system.

Does a great job! Put this in a 70 Cougar along with a RetroSound radio and sounds awesome.Would not fit under the seat but works great in the trunk.



My factory speakers sound better..

Joe from Louisiana on 5/26/2012

Crutchfield Customer Review (What's this?)

I really can't believe all the glowing reviews on this sub. This will simply not satisfy you if you've ever had decent sound before. I've had 1 10" sub in most of my vehicles and this Sound Ordnance 8" package comes NOWHERE close to the performance of 1 10" sub in a sealed box. I have been adjusting this thing for weeks trying to find some nice sounding bass but I just can't find it. My stock 6x8's and 6" speakers have a better sounding bass note and they hit just as low (seriously). Do note that this thing does not hit very low either (less than 50hz).. but that is stated as the frequency range so I did know that going in. Hope you don't like Rap/Hip Hop b/c you'll be missing a lot of low notes. I listen to all types of music and my stock speakers' bass is much tighter and better sounding. I already contacted Crutchfield about returning it and they're hitting me with 10% charges everywhere to send it back + $$ if I don't send my "free" wiring kit back.. Lovely. I get to waste another day taking this thing out of my truck now. Not happy. I would give it one star, but the price on sale was so good and the fact that it is an all-in-one unit made me increase it to two stars. You mihght be happy if you've never had real bass, otherwise, save a little bit more and go with a separate sub & amp.

Pros: Small footprint, price (when on sale and free wiring kit), nice wired remote gain knob

Cons: Boomy bass. Can't come close to hitting notes below 50hz. I spent some time modifying my truck for this guy and now I have to send it back. No mount holes in the unit makes non underseat installs challenging.


Crutchfield customer from wilmington de on 5/22/2012

Crutchfield Customer Review (What's this?)

Installed this behind the passenger seat of my 87 fiero gt. The fit was beyond perfect. Sounds amazing and actually is loud and really tight. You can deffinately feel the punch when the bass hits. I recommend this to anyone who has a 2 seater. It wont rattle your windows but it more than gets the job done



Great underseat sub

Crutchfield customer from NY on 5/22/2012

Crutchfield Customer Review (What's this?)

This little box packs quite a punch, and a great value. Best bang for the buck in my opinion for those that are looking for a little bass but not too crazy.

Pros: Good bass, cheap price.

Cons: Only downside is that the terminals on the amp is made of some weak metal so be careful when your tightening the terminals up.

THE 30 Something FAMILY DAD from NORTHERN, NEW JERSEY on 5/18/2012

Crutchfield Customer Review (What's this?)

I own a 2011 SUBARU Legacy. I was amazed at how many poor reviews I saw in my research about this unit. I would consider myself a fairly knowledgeable person in the arena of audio and visual electronics. I am not a tech or a nerd but I crave great sound. Here's what I got in my SUBARU. Why did I decide to buy it? I want more bass in my car and the factory speakers x6 sound decent for my present needs but I was missing that bass. I didn't want to give up ANY TRUNK SPACE! With a FAMILY That is not acceptable for my needs! First step I replaced my HEAD UNIT (HU) for a JVC KW-NT50HDT. It is a nice DVD NAVIGATION WITH Traffic UPDATES in this unit and Crutchfield provided a perfect fit with needed wires for an easy install. Hooked up now to the SOUND ORDINANCE B-8PT12 with the wiring kit I bought from Crutchfield and my car thumps. I only have it turned 3/4 of the way on the AMP and half on my HU. I listen to hip hop from the 90's, 80's rock, House Music, and Reggae. With the windows down you can't hear me from blocks away but I don't care. I'm a family man and when the kids aren't in the car...the music thumps! This isn't the same bass I had when I was in High School (2) 15" house speakers in trunk.... but this product exceeded my expectations. I have only had it for a week and am very happy. I know from previous experience it will sound even better after I break in this speaker but am having fun doing it.

Pros: Fits perfectly underneath passenger seat, Provides my wife with a nice butt massage as we drive. IT bumps! Unless you want to be heard blocks away, this is more than adequate, It comes with a wired remote (knob) to turn bass down for kids in car an my mom who doesn't care for the bumping! THE PRICE IS SO REASONABLE!

Cons: I should have bought this sooner when I purchased my HU a year ago, missed out on some quality enjoyment!

great piece of equipment.

kfoell from dallas, pa. on 5/18/2012

Crutchfield Customer Review (What's this?)

i have two of them one in my work pickup and one in my other pickup. love that they fit under the passenger seat perfectly. keeps the dogs from stepping on them... never knew pink floyd and led zeppelin would sound so good with a little extra punch. favorite part is the dial remote. allows me to tune to the sound for each song without taking my eyes off the road. great price, great sound, i guess if you like crap, i mean rap music it might be lacking the punch you seek. but for classic rock and roll it is great... buy one now you will not be disappointed...

Pros: size, sound, electronics, dial remote. all are perfect to supplement any sound in any vehicle.

Cons: none

Excellent Punch for the Value

DCLAguy11 from Arlington, VA on 5/17/2012

Crutchfield Customer Review (What's this?)

This is an excellent value if you are looking for an easy and effective way to add bass to your exisiting system in a small package. It might almost be too much for a stock stereo. I used this to compliment the upgrades I made to my stock speakers and it works excellent in my Toyota Tundra Access cab. If I turn it way up it's almost too much bass. I can see why the ratings are so high.

Pros: Small size, great value, excellent bass, easy installation

Cons: Have to make adjustments based on music types (A better head unit might help)

It's good for what it is.

Thebassdan from Pittsburgh, PA on 5/16/2012

Crutchfield Customer Review (What's this?)

I'm an active bass player. My standard cab Ranger has very limited room. I needed more bass from my audio system. The Sound Ordnance B-8PT was the only subwoofer that fit behind my seat (and from all the reviews I've read) doesn't over heat. Seriously, if an 8 inch speaker could deliver the bass of my 15" cabinets, I would not need my truck. - Bottom line, I'd buy it again.

Pros: Size, price, and build quility.

Cons: (In a world without physics,) lower frequency response would be nice.

Cons: Not good for some one who's looking to feel the bass

Great While It Lasted

Scotthew from Nevada on 5/13/2012

Crutchfield Customer Review (What's this?)

Put this in my 2010 Impreza in August 2011. I love that it was able to fit under the passenger seat, and no cargo room was sacrificed. The bass is impressive for it's size. It's a little bit "boomy" depending on the source, but acceptable considering the trade off. A couple months ago (after about 7 months of use) it developed a strange buzz note. It was sporadic at first, but has grown to a be a constant problem. It's higher pitched buzz above the bass tone, and extremely noticeable during talk radio, commercials, or audiobooks (mainly cause music drowns it out). I don't ever crank the bass and volume high (I don't like hearing the doors and windows buzz). I'll be looking into warranty replacement.

Pros: Size, All-in-One Convenience, & Impressive Bass for its Size.

Cons: Failure in Less Than a Year & Somewhat "Boomy" Sound Quality.

Great Sound!

Alex from Denver, CO on 5/12/2012

Crutchfield Customer Review (What's this?)

This is a great product for tight installations or for car and small suv's. I have bought 3 of these powered sub's and they work great! They really make a difference on bringing music to a higher level. If anyone is considering on buying this product, I would honestly tell you is an awesome product with 3 years or warranty.

Cons: none

perfect for Jeep TJ

Perry from Kathleen, GA on 5/9/2012

Crutchfield Customer Review (What's this?)

I read the reviews and someone mentioned that it fir under their back seat in their TJ. I admit I was skeptical it would fit and even more skeptical it would sound good. I was wrong. It fits like it was made for my Jeep and it sounds awesome. I now am able to use the HPF filters on my front and rear speakers and the bass that comes from this unit is superb. No, it won't shatter any windows but it makes my stereo sound beautiful. I am running a Kenwood KDC-X395, Alpine KTP-445U, and 4 Boston Accoustic speakers. My Jeep sounds better than I thought possible. If you own a Jeep, you need this sub, period.

Pros: Compact, easy to use, easy to install

Cons: None


Nate from Tn on 5/8/2012

Might be a good sounding product in a simple stock stereo system but for me I have the bose system and its not much better. Adds a little more but really not enough. With that being said good sounding 8 in.



Sound ordinance 8" pwr sub

Crutchfield customer from Oklahoma City on 5/8/2012

Crutchfield Customer Review (What's this?)

I'm 40 plus yrs old and this was a perfect fit for my 06 f-150, just enough punch to separate my after market component speakers & gives me enough base to eliminate distortion! It's great for those purposes and a great buy for the money especially with the wiring kit so u don't hv to buy anything. Installing it was a 1 hour job with minimum skills! Great work Crutchfield I am satisfied with my purchase and will continue to trade with u guys in the future.

Pros: Solid clear Bass

Cons: Could have a tad bit more Bass but very noticeable.

Sound Ordinance good so far

Crutchfield customer from Philadelphia, Pa on 5/7/2012

Crutchfield Customer Review (What's this?)

This little sub has perfectly fit the bill so far. I mostly listen to rock and some jazz with some western concert music occasionally. I paired this unit with some Boston Acoustic SE45s in the stock dash locations, in my 94 Toyota Extra Cab Pickup. The sub just fits under/behind the passenger seat and in the small area of the cab, fills in the gaps left by the tiny 4" dash speakers. I have to say I was initially unimpressed with the head unit and dash speaker replacement but when I added this, I am more than satisfied for now. Not only does it add the punchy lows, it also fills in much of the mid-range that the 4" dash speakers can't touch. I am very happy with the overall sound and between the adjustments available on the amp/sub and the adjustments available in the head unit, the possibilities are endless. Crutchfield's service and helpfulness are unmatched.

Pros: Space saving, easy installation, good mid to low range.

Cons: Limits are clear when listening to bass heavy music like rap and hiphop and doesn't hit like a bigger sub but, that should be obvious.

Sound Ordnance™ B-8PT

Crutchfield customer from Washington State on 5/6/2012

Crutchfield Customer Review (What's this?)

Surprisingly good bass. It's not going to vibrate all the glass in your car, but it will definitely fill in some low end bass.

Pros: Easy, Easy to install. About the size of a cereal box. Fits anywhere except under you sun visor. Remote bass control.


Good thing in a small package!

Tony from Williamaburg, VA on 5/6/2012

Crutchfield Customer Review (What's this?)

I was skeptical because I have never used the brand before. But after reading the other reviews I decided to try it out. It fit perfectly under my rear seat in my Jeep Wrangler and sounds great. Just enough bass, and not overpowering. Installation was a breeze too. I don't think you can beat this for the price! Gotta love Crutchfield!!!

Pros: Price, installation, size, sound

Cons: None


DB from ks on 5/6/2012

Crutchfield Customer Review (What's this?)

Killer, not for those who want people down the block hear and since you can't hear that sound in your car (think wavelength and distance, or don't) it produces sound within the vehicle down to 48 hz (rta variance .003) . I rest my case:o)

Pros: accurate reproduction within specs

Cons: really needs to be more flashey, oh yes and bigger, bigger is better right?

Great sound

Wolf from Near the beach, California on 5/6/2012

Crutchfield Customer Review (What's this?)

I love this box! It really was the " missing link". Such great sound out of such a small unit. I wasn't looking for thumping base, just something more than what i had and this fits the bill. I have it mounted behind my rear seat in my Ford crew cab. Def worth I installing.

Pros: Great sound, Small, nice looking unit, remote base adjuster

Cons: Constantly adjusting base

Good Bass for my Jeep

JimboCJ7 from Chapin, SC on 5/6/2012

Crutchfield Customer Review (What's this?)

I have a '78 Jeep CJ7 with a soft-top and sidepipe mufflers. Getting good bass from my music has always been an issue, and with very limited interior space I needed a subwoofer that could fit under my rear seat. This subwoofer is awesome! Hook-up to my existing powered amp was easy, and the remote control dial for determining how much bass I need fits nicely on my center console. At highway speeds, with the top down, I hear every note! Definitely worth the money, and no regrets!

Pros: Compact size, self powered, remote control from driver's seat

Cons: None, for what I needed.

good bang for the buck...

jb from lexington ky on 5/6/2012

Crutchfield Customer Review (What's this?)

I was really aprehensive when I recieved the unit ' it was so small ! But after hooking it up it performed well beyond my expectations .

Pros: small very afordable

Cons: no hardware or brackets to mount it keep it from sliding around

Shallow Subwoofer

Brandon from Rock Springs Wy on 5/5/2012

Driving a LP 560 Spyder, Lamborghini! Entirely has NO space with very limited stock speaker range! I purchased this unit to fit behind passenger seat! Done Deal!!!!! Lamborghini Automobilia should make this item Stock! Serves as a unified and extremely competent bass tool to complete the stock system!

Pros: Compact with HUGE Bass!!!

Cons: If connected via speaker wire from stock door speakers, must turn stereo loud before Bass system activates and joins in concert with rest of speaker system! Just a technicality, probably can be overcome with skilled installer!

Surprising unit

ScottH from St. Louis, MO on 5/5/2012

Crutchfield Customer Review (What's this?)

This unit had me worried when I first fired it up. I have it wired high-impedance, from my factory speaker wires. It didn't come on until I turned the volume up quite a bit. This bothered me for a day or two. Now I see the genius behind it as I can listen to normal volumes with no bass from the b-8pt then crank it up when I want to play. Will keep my wife and younger son at normal volumes and then my older son and I can rock out. Sounds awesome with rock, needs a little more fine tuning of the phase and other adjustments on the unit with hip-hop. Just haven't done it yet. Fantastic value when paired with free amp install kit. I ended up putting on the back deck, securing it with the bolts from my factory LATCH anchors. Also gave me a convenient point of ground. I do have a little buzz when I listen to my iPhone, but that's another adapter. Eventually I want to get a new head unit that will allow me to run the b-8pt from the RCA inputs and the iPhone directly through USB.

Pros: Took bass load off of my weak factory speakers. Can go louder now w/o distortion. Small package. Love remote.

Cons: Not super bass like my friend's 12s. Wouldn't want that anyways. Slight buzz with iPhone, but may not be this unit's fault.


Tgroove from Chandler, Az on 5/5/2012

Crutchfield Customer Review (What's this?)

Bought this for my 2005 Double CabTacoma. Originally planned for it to go under passenger front seat, due to an amp already under the driver seat. Low and behold, it no worky under passenger seat. Just too tight. Decided to go behind backseat space on driver side. Perfecto my friends! It was made for this space. Took it to another retailer and had their Geek install it. Couldn't ask for a better experience. I don't know why I lived without this little gem for the last 6 years. I upgraded the factory speakers years ago along with a nice 4 channel amp, but still wasn't happy. Then I upgrade the factory deck to a Kenwood, still not satisfied with big sound. Saw the S/O for the price, so I pulled the trigger. Just wish I had years ago. This thing is exactly what the Dr. ordered. Big full bass sound and when dialed in correctly, punchy kick drums and solid fat bass lines. Sound Ordnance...I am a believer-Thank You!

Pros: Sound, size, EQ adjustments

Cons: Can't do enough drivin' around to listen to this baby

Just what the Wrangler needed

Terry from Olney, MD on 5/3/2012

Crutchfield Customer Review (What's this?)

This is what I needed to round out my sound experience in my 2010 Jeep Wrangler Sport. Having replaced all the speakers, the HU, and adding a Kenwood amp under the passenger seat, the Sound Ordnance found its home under the driver's seat. It barely fits! I had to remove the seat first. After it was wired up, I replaced the seat and all is good. I had no idea how much I was missing until I fired up this baby. Everything from old school rap, to rock, to brand new country sounds simply awesome. Words can't describe how this sounds. This is my very first subwoofer, so I can't compare it to others. You have got to hear it for yourself.

Pros: Easy set-up. All-in-one solution. Great price.

Cons: None so far.

This small sub packs a big punch. Installed on a 1996 f250 ext cab inside the factory center console. I didn't want overpowering bass just enough to compliment my aftermarket full range speakers. This sub greatly surpassed my expectations. I would definitely recommend this to anyone.

Pros: Small design, great bass, price

Cons: None!

2010 Dodge Ram 1500 Quad Cab

John F. from Panama City Beach, FL on 4/26/2012

Crutchfield Customer Review (What's this?)

The Sound Ordnance B-8PT will work for me. I found the best place to mount this was under the driver's seat of my 2010 Dodge Ram 1500 Quad Cab for ease of wiring. Actually, I didn't mount it at all, I just set it there. Putting it there also makes the controls easy accessible from area behind the driver's seat. It would have also fit nicely on the ledge under and behind the rear seat, but wiring would have been more of a challenge for me and the controls wouldn't have been as accessible. The wiring kit that comes with the Sound Ordnance was perfect as it had all I needed to get the job done. Used the RCA connectors to connect to my Sony MEX-BT4000P. Connected the remote terminal of the sub to the blue/white remote on wire of the head unit. Unit turns on automatically when I start the truck and turn on the head unit and shuts off when I turn off the head unit and/or ignition. The wired romote comes with double stick tape and I stuck it to the side of the center console just in front of my seat within easy reach with the control knob facing up. It sounds good. It has enough umph to feel it through the seat when you crank it up. I now have a sound system in my truck that makes it very enjoyable.

Pros: Fits nicely in a 2010 Dodge Ram 1500 Quad Cab. Price is half that of the competition. Wiring kit comes with it. Easy to wire. Good bass sound.

Cons: None

Great with system

Ryno from Adks, NY on 4/24/2012

Crutchfield Customer Review (What's this?)

This is the perfect amp/woofer for smaller type vehicles when your not trying to break windows of other passing vehicles. The system mounted perfectly under the passenger seat and perfectly augments the Polk Audio speakers that they are integrated with. Price was good and the wiring kit was included at no charge! Great for rounding out the sound of the system.

Pros: Integrated amp/woofer and fits under seat.

Cons: will not mount vertically since it is only held in place with velcro. I used some foam padding and very large zip ties. worked great

perfect accent to my system...

navydude from Virginia Beach on 4/24/2012

Crutchfield Customer Review (What's this?)

This little guy is just what I needed to finish out the system on my baja. Being my daily driver, I was not concerned with breaking 2K RMS on my subs like any other system I may be interested in. I do have an after market HU and all the doors have been replaced(type S alpines/components), but i still needed a little more. Having the B8PT allowed me to get my EQs comfortable on the ears without over emphasizing any freq's or distorting my other drivers. It barely fit with a little leg work(literally to get the seat back :) However, whether watching a movie or the classic rock is going on my way home, it hits n keeps hitting like its it's day job. Now, understand, this is NOT for dropping bottom or dropping that much of anything for the matter. All that being said...There are literally almost 400 reviews on this thing, and who knows how many haven't reviewed that have bought it. Crutchfield did their research and moreover a great job with their house brand here.

Pros: punchy, tight, size, minimal power draw.

Cons: Low end cut off. I understand, figuratively there is maybe a couple cubic inches of airspace in this thing, however, the drop off after high 40Hz and below is like hitting dead air. You may even think you blew it or it turned of, but just let the song go and your bass line to walk back up into a B8PT-usable frequency and itll let you know its there again...thats my only star off

Great Bass for Price, Fought Trouble with Alternator Noise

JohnG from Abingdon, VA on 4/23/2012

Crutchfield Customer Review (What's this?)

Installed in Chevy Silverado extra cab truck under rear seat. More than enough Bass for classic rock or modern country music. Initially connected to component output of Sound Ordinance 4 channel 75 Watt amp. Created "alternator whine" through speakers. Tried everything to eliminate the problem. Added filter which took out alternator whine but it killed the output of the sub. Finally connected sub through high level inputs (speaker outputs of the dash unit) and it has been excellent ever since.

Pros: More than enough Bass for classic rock / country music. Easy to install and adjust. Delivers what it promises. Crutchfield support was great.

Cons: Had alternator whine when connected with component cables in my particualar configuration. Connecting with high level inputs corrected the problem.

The little sub that could

Crutchfield Customer Review (What's this?)

I am very pleased with my selection of this powered sub woofer. I based my decision from the customer reviews and they were right on. This sub sounds great, especially for such a compact size. It fits neatly under my rear seat of my 02 GMC 4dr Sierra , with plenty of spare room and was easy to install. I am impressed with the quality of Sound Ordnance and the WWII art work on the box and catalog is pretty cool.

Pros: Easy to install, sounds great and well made. The free 8ga. wiring wiring kit was a plus.

Cons: The included Velcro strips did not want to stick to my carpet, Metal mounting strips would be ideal for permanently mounting to the floor board

Excellent, compact power

Jerms from Kalamazoo, MI on 4/22/2012

Crutchfield Customer Review (What's this?)

This was the first subwoofer install ever for me and I was looking for something with decent power, small in size, and user-friendly for a newbie to car audio. I really don't like huge, punchy bass and wanted a sub to really "fill up" the sound in my 95 Toyota Avalon. It has 4 door speakers and 2 mini-tweeters, and the factory amplifier cannot handle everything at high volumes. Changing it would be a huge issue because it is very small and installed behind the glovebox with very little room to re-wire anything. This powered sub would solve my bass problem and the factory amp could remain, focusing on the 6 speakers alone. Install was simpler than I thought and the end result was fantastic. The sound quality and volume is excellent. You can certainly hear me coming but not from a block away, like some subs. My system is as follows: JVC KD-AHD79 head unit 4- Polk Audio db 501 5" 2-way Speakers in doors 2- Factory tweeters Factory sub and this sub installed under passenger seat

Pros: Excellent sound, compact design. Free promo wiring kit was a big plus.

Cons: Instructions are VERY basic with very little photos or diagrams. I learned more from online forums on how to install it best. Crutchfield had no printed recommendations included either for my vehicle.

More than Satisfied

Steve H from San Diego, CA on 4/20/2012

Crutchfield Customer Review (What's this?)

This subwoofer is just what I needed for my Scion Xb. It fits under the driver's seat and reproduces the low end of the sound spectrum exactly the way I was hoping it would. This is not for anyone looking for the lows to overwhelm the rest of the music but fantastic for bringing out the low end to complement the songs. Now that I know this unit exists I will be recommending it to any one that want's to add some punch to their factory car stereo.

Pros: Reasonable price, fits under car seats, came with free wiring kit, good sound and a terrific recommendation from the staff at Crutchfield

Cons: None

Loud little thing!

Impressed from Aniak,AK on 4/17/2012

Crutchfield Customer Review (What's this?)

I replaced a blown powered woofer with this unit and I am impressed with the bass that comes out of it for how small it is. I would have given it a 4 but it didn't come with any mounting hardware! Maybe because I bought it used and refurbished? But it is a cool little woofer, happy with the buy.

Pros: Good size and sound.

Cons: no mounts


Tom from Indiana on 4/17/2012

Crutchfield Customer Review (What's this?)

Put this under the seat of my 2010 Tacoma, it made a huge difference in the quality of sound my aftermarket system can produce, it did take a little adjusting to get the sound right, but after that I was very satisfied with bass and overall depth it was able to add to my music. Love the remote gain control, very handy to add or take away bass from song to song. Very impressive for such a small package!

Pros: Great bass that will fit under the seat, the gain remote rocks!

Cons: The double sided tape on the remote is worthless.

Must have for Jeep

firefly21 from Burgettstown PA on 4/16/2012

Fits under the rear seat of my 06 LJ Wrangler. Adds plenty of pound. If your on the fence just do it. Once "dialed" in you will think, dang I should of done this a long time ago. Like others have said you are not going to shake mirrors of the car next to you but you will feel & hear a substantial improvement over stock.

Pros: small, plenty of sound, easy to install

Cons: zero

Great Compact Unit

Lionel from Puerto Rico on 4/14/2012

Crutchfield Customer Review (What's this?)

Great sound quality and the perfect compact size so that it won't take up a lot space in your trunk. Furnished my own brackets and pinned to back of seat for even more space saving. I would suggest that crutchfield include these brackets also with every purchase. As always amazing customer service.

Pros: Size, sound quality

Cons: Brackets to fix to back of seat not included

Works Great in Single Cab Pickup

Mike M. from Texas on 4/13/2012

Crutchfield Customer Review (What's this?)

Threw this in with a Kenwood receiver/speaker deal I ordered a few months back, for use in a crusty old 1993 Ford F-250 single cab pickup. There wasn't enough clearance under the seat, so I had to put it behind the seat. The amount of bass this thing puts out considering the size of the enclosure is extremely impressive. I bought a powered Bazooka bass tube many years ago for a hatchback, and it not only cost more, but also sounded really muddy and poor compared to the Sound Ordnance B-8PT. This unit is hooked up to the receiver via RCA cable using the head unit's preamp output. The receiver has a plethora of controls and settings for shaping sound output and frequency cutoff points etc., so the included "remote" knob was not needed. The B-8PT easily shakes my rear view mirror, and it's one of the few things left on this relic that's still tight. I can't speak for how effective this product would be in a larger vehicle, but in the close confines of a pickup, with the thing either right under or behind you, it could easily double as a massage device. I have to say, out of all the audio gear I've ever ordered from Crutchfield over 20+ years, this "in-house" brand, small subwoofer has been one of the more impressive deals for the money.

Pros: Fills in the bottom end quite well. Puts out an impressive level of bass given its diminutive dimensions.

Cons: The bass output isn't quite as tight as I would prefer, and does seem somewhat "boomy". However, it is certainly acceptable considering, and a far better choice than a powered Bazooka tube of similar size.

I was a lil weary about buying an 8 inch sub but it sounds pretty good in my little Tacoma.. If you are going for a lil added bass then this is what you are looking for.. Its very slim so it will fit behind the seat in the truck with room to spare..

Pros: Will fit anywhere.. sounds good..

Cons: Doesn't have the bottom end sound of a 10 inch

I was not sure if the speaker would be real good before I ordered it; but now that I have it installed, I'm impressed. Had to make some adjustments on radio and amp, and now it rocks!! Recommend for people that don't have much room for a sub.

AaronK from Starkville, MS on 4/3/2012

Crutchfield Customer Review (What's this?)

I needed a little bass in my 2005 Chevy. This thing has given me just that. It sounds great for such a small amount of space sacrifice. I was looking into a Bazooka tube but the Crutchfield advisor talked me into this instead. I'm glad he did!

Pros: Relatively easy install. A volume control knob came with it, which I really liked.

Cons: Don't have any yet.

Great bass from a tiny package

af_1 from Missouri on 3/31/2012

Crutchfield Customer Review (What's this?)

I don't have much more to say than everyone else, since just about everything has been covered already. The subwoofer fit perfectly under the driver's seat of my 7th-gen Civic Si (EP3), and doesn't affect the seat's sliding movement. I don't think it would have fit if it was any bigger, though. My Sony DSX-S300BTX receiver can control the sub's volume, so I set the gain where I liked it, and didn't use the wired remote, since there's nowhere convenient to put it. The Velcro strips are pretty weak, so I replaced them with some industrial strength Velcro with much better adhesive, and a larger coverage area; I'd suggest you do the same. In my small car, it's more than enough bass output to be annoying, and that's with the gain set about about 30%. Sound quality is good, but a little boomy, as apposed to being perfectly accurate. But, inside a vehicle, with all the ambient noise, it's not noticeable. Overall, I'm very happy with the subwoofer. It's nice adding extra bass, while being able to keep it completely hidden from outside (or inside) view, and without taking up much space. For those who want even more bass, I'd suggest buying two of these, and mounting one under each front seat.

Pros: Size, price, bass output, ease of installation

Cons: A little boomy

If you looking add a clear bass to your factory system its perfect!,.. But if you looking for a monster bass like shake the mirror or if you want to listen the bass around 1 block away! Its NOT for you. I bought this subw for my F150 07 crewcab and fit perfect under the rear driver side & sound great!



More than enough bass

C.W.C. from Kansas City, MO on 3/29/2012

Crutchfield Customer Review (What's this?)

After reading the reviews here, I decided to purchase this sub as a scratch and dent. I've purchased scratch and dent receivers before and have always been pleased, so I knew any scratches on my sub would be minimal. I've installed this sub under the driver's seat of a 2008 Honda Odyssey EX-L. I have this sub connected to a Kenwood DNX6960 receiver. This sub fit perfectly under the driver's seat and provides more than enough bass to fill the van and exceed my expectations. The remote is nice since it provides the perfect amount of adjustment with differing songs. In high school I had the car with two 10's in the back, and ten years later, this sub satisfies my stereo needs. Unless your 17 and in high school, this sub will exceed your expectations when it comes to providing bass. If you want more bass than this sub provides, you're just asking for hearing loss.

Pros: Excellent bass and compact size

Cons: None

nice fit,great sound for size

good for extra bass with little room

Crazy Canuck from Thunder Bay Ontario Canada on 3/23/2012

Crutchfield Customer Review (What's this?)

Just finished install in my 2005 Dodge Dakota extended cab. Looking for a little more bass and a deal to boot. I did my homework and decided this sounded like the way to go. There is absolutely no room for extras so this fit the cab and the pocketbook. Picked up this unit with free cables included. Highly recommended. Everything was there for that professional install. The only thing I bought was tap connectors to hook up to my back door speakers. Took me a couple few hours but I'm picky that way. I chose to mount the sub on the back wall between the folding seats. I have no regrets. It's a little too nice to be hiding under a seat. Controls facing up and wiring down. I used hidden mirror clips and a little velcro for added protection. Bonus the grey colour matches my interior perfect. The unit weighs in at a solid 10 lbs. I really like the remote level control. As others said, the 2 sided tape has something to desire, my control fell off my dash this morning. I just picked up a heavier duty tape. I still have the stock audio system the truck came with and with the added bass I'm quite happy with it. Kids, you won't win competitions with this so keep walking. This 50+ year old still likes to listen to classic rock so bring on the kick drum! Thanks Crutchfield for this product and your service!

Pros: size, remote control level volume, construction

Cons: better mounting for remote control

Great Compact All 'N' One Package

Pale Screw from MidWest on 3/21/2012

Crutchfield Customer Review (What's this?)

This is a great compact all in one package. It has a nice thin, and unobtrusive profile. This sub is easy to setup, and install. I purchased 2 of these subs for the back of my 2011 F150 SuperCrew, and installed them behind the back seat of the Crew Cab. They fit very well, and I can still lock the seat bottoms up to gain complete access to the load flat floor without loss of floor space. This sub has an onboard amp that allows you to wire directly to the sub, and Crutchfield provides a free wiring kit that works perfectly. This sub provides a good punchy bass with plenty of power for it's size that fills the listening area very well. Especially with 2 of these. Now I can shake the mirriors, LOL.

Pros: Thin and unobtrusive. All N One enclosure with onboard AMP. Easy install with free wiring kit from Crutchfield.

Cons: None so far

Install in 2001 BMW Z3 roadster

Kenny from Northern NJ on 3/21/2012

Crutchfield Customer Review (What's this?)

Very impressed with capability of this product. It is mounted atop of the footwell on the passenger side facing down. Just the right power and punch for my car. I have/had many cars with serious sound systems (10k to 20k) and this product for a low budget upgrade (under 1k) was beyond perfect. I highly recommend this product to any individual looking for a clean low budget upgrade. Low end base is crisp and for what it is worth you can't ask for anything more. Form factor is great to fit tight areas in especially smaller cars. Only downside is that when the top is down and at cruising speeds you will lose about 60% of the punch from the low end bass but then again it is NOT a 12 inch 1000 watt sub enclosure.

Pros: great form factor. great low end bass. clean and crisp sound.

Cons: when top down in a convertible lose about 60% of the feel of low end bass.

Perfect size, decent power, great product!

N8Marsh from Raleigh, NC on 3/20/2012

Crutchfield Customer Review (What's this?)

Fits absolutley perfect under the driver seat of my 03 Civic sedan. Autocross tested, didn't budge. Sub does not have the hit of full boxed units (still shakes the rearview), but performs acceptably in mid and high bass tones. (Biggie, Hypnotize is the best beat to flex this sub) Get this sub if you actually use your trunk and don't want to lose any of it.

Pros: size fits anywhere easy install

Cons: doesn't "hit"

Perfect if you dont need to jump on your seats

This unit is my best investment in my car audio. Installation in my Nissan Versa 2010 SL was not easy. Spend some time to get cable thru the fire wall but when I turned that SUB ON.. It's like I got new car for me. What a huge different. I got it installed with Alpine KTP-445 Head Unit Power Pack 45W x 4 Car Amp and Alpine HU. Alpine Power pack makes the sound level of the SUB and Alpine HU almost perfect. Never wanted SUB in my car before, will never drive my cars without it. Very impressed and very happy. Thank you Crutchfield for recommend me that !!!!!

Pros: love it.

Cons: NOON

Crutchfield Customer Review (What's this?)

This is a great little sub. I installed it in a Dakota quad cab. There is basically no where it put a regular sub box in this truck without taking up some backseat space. This thing fit nicely under the front passenger was tight but it fit. I have a Kenwood head unit and Boston acoustic 6.5in in all 4 doors which sounded great but was missing some bottom end, this little sub filled the low end gap perfectly. It actually delivered more punch than I was expecting to get from such a small package.

Pros: none that I've found

Cons: none

Geat Sub

M3Z from Addis, LA on 3/13/2012

Crutchfield Customer Review (What's this?)

This powered sub is great. Rich sound and easy install. Amazing low end for a suprisingly small enclosure and moderate power. This sub was a perfect fit under the drivers seat in my Dodge Quad Cab 1500. The only reason I didnt give it five stars was because the built in EQ limits the sub to 200hz. It should allow for a broader reach, especially upward into the midrange where the sub would shine a bit more. Great deal for this sound!!

Pros: Small size make it fit just about anywhere. Easy installation. Great Sound!!

Cons: Equalizer bandwith limits range too much. Can easily be fixed with a radio controlled EQ or an aux Eq installed upstream.

Very cool product

AlanD from Holland, MI on 3/13/2012

Crutchfield Customer Review (What's this?)

I just installed this product in my 1973 MGB/GT and it does exactly what I was hoping it would do - add some good rumble and punch to the low end of my stereo system. I have a Sony radio/iPod head installed that currently powers 2 6x9 Sony Xplod speakers in wedge boxes in the rear. They sound fine, but especially at higher volumes or when my car (which is loud) is running at speed the bass disappeared. With this subwoofer installed below my shelf in the spare tire compartment I now have all the rumble I could want. I'm running the line-level inputs with the remote wire hooked up and it has performed admirably so far. When I purchased it this subwoofer came with an 8-gauge installation kit for free, which was very helpful as well.

Pros: Very small, convenient package. Easy to install and does exactly what you'd expect it to do.

Cons: Yeah, it's missing some of the ultra-low frequencies, but if you're really concerned about having THAT much bass you should probably be looking elseware. Would be nice to have fixed mounting points instead of just velcro.

Does ok

Erik from Massachusetts on 3/12/2012

Crutchfield Customer Review (What's this?)

Overall left me wanting more. If you have ever had subs in your trunk this is not for you. Bought a new car and didn't want to have big subs and amps everywhere. This fit snugly under the passenger seat of my '09 Sonata. If you have power seats make sure you measure. This does fill on the low end of a factory system but lacks any real punch. I don't want to down the product because for what it is I guess it does well. I just know a year from now I will be saving for a proper sub.

Pros: Good build quality. Very compact and should fit under most seats.

Cons: Lacks "punch". I don't know what I expected but I will be upgrading to proper subs eventually.

Great Product!

Benwa from MS on 3/11/2012

Crutchfield Customer Review (What's this?)

I have a small hatchback with factory speakers/head unit. I needed something to balance out the system. Perfect choice! This delivers more punch than I was expecting. My premium factory system now sounds like a premium system. I mounted it in the back of the car, and after a bit of tweaking on the controls it sounds perfect. Great quality so far. My only complaint is that the remote wire for the level remote is very short, and the mounting tape is worthless.

Pros: Size, Sound, Quality Construction, Price

Cons: Very Short level remote wire, Cheap mounting tape, Only included Velcro for mounting sub.


fc3c from campbell, ca on 3/10/2012

Crutchfield Customer Review (What's this?)

yes! first i will say that i was not expecting the thump of 12" million watt sub in a box that cost more than my car. with that being said, this little guy is perfect. i have an 88 rx7 convertible and there is not alot of room for much of anything. putting a sub in the trunk would mean i couln't use it for anything else. especially since the targa section of the roof requires the entire trunk if you take it off. being a small mazda putting anything under the seat was also not an option. the only place would be behind the seat or under the spare tire in the middle of the car. i opted for the space under the spare. because of the limit space this sub was the only option for me. i just assumed it would be crap and under powered but i got one anyway. what an amazing little device! loud and crisp with no hint of rattle! like i said before i was not expecting crazy low lows so i am more than happy with the sound this little guy can put out. for people that say that it is too quiet or sounds bad it just must be set up wrong or your car is too big for it. i think to get the best out of it you need a proper sub pre out, some empty space around it, and use of the phase control either on the sub or in the head unit. this unit was exactly what i needed to fill in the dead spot in my sound range. i am currently using a sony xav-60 head unit, infinity 4030cf two-ways upfront, 5030cs components for the door woofers, 329cf two-ways in the the head rest, and an infinity multi chan amp

Pros: great sound in a tiny package. this thing is seriously small. crisp sound all the way to 80hz. simple setup, just took 30mins to get in an set up

Cons: would be nice for some sound uner 80hz but just not gonna happen in a package this small

Good for the size.

Nate from Windsor, CO on 3/3/2012

Crutchfield Customer Review (What's this?)

I give this sub four stars mostly because of the size of the unit. It is easy to install and set up, and produces impressive base from something so small. All that good stuff being said, and I was still unhappy with this sub. I just could not get it to sound the way I wanted. I have been trying to get the sound in my 2012 WRX up to par. It originally came with the new Subaru Kicker 10" sub, and that was so overpowering and droning that I removed it in the first day. Next I installed a pioneer 4400bt, and grabbed this sub. I did not replace the factory speakers, as they are pretty good. This sub has bass but it is not punchy. This is due to that its lowest response is 40hz, and personally it seems more like 50hz. I could never bring out that rumble in music, or the low bass lines in jazz and pop music. If you want that really low, smooth, tight bass, nothing beats a sealed wooden enclosure with a good 10in sub. I have returned this, now have my old 10in box back in, and am happy with the sound.

Pros: Super bass from a small (really small) box. Easy setup, and use.

Cons: No real low bass frequencies to be found.

Pretty Good For It's Size

GlennM from Tampa Bay on 3/1/2012

Crutchfield Customer Review (What's this?)

I had high hopes for this after purchasing 2 of the SO B-8P Powered subs for my kids cars. It is pretty impressive considering it's size, but if you have the room for the standard non- flat model, you'll be much happier. Much deeper/cleaner bass, even at only 80 watts and not that much bigger. Also the B-8P is $60 cheaper. This is good if you have to put it under a seat(pick up truck). It is very well made and a fairly decent buy @$199. A definite improvement to a stock factory system. Also noticed that if set on the "auto-on" switch, it will sometimes turn off at lower volumes.

Pros: Small Size, well made

Cons: B-8P a better value/performance if you have the room for it.

Nice Supplement

Don W. from New Jersey on 2/29/2012

Crutchfield Customer Review (What's this?)

I have this installed in a 2008 Silverado extended cab truck. In the four doors I am running Polk DXI650's and have this under the rear seat on the drivers side. Also in the truck i installed a Advent OGM-1 deck for a nice factory look but with aftermarket performance that drives the Polk's. I am a person that was looking for a very clear and well balanced audio system that the Polk's alone could not produce. The B-8PT added great depth that was not overpowering to the overall sound. This sub, when used within its limits will produce rich, useable bass but will not handle ultra low frequencies that are over driven. So if your looking for big boom, ultra low vibration, bass that travels down the road before you do, this is not the sub box for you. If your looking to increase your bass to create a well balanced sound this is your answer. My hats off to Crutchfield for offering such a nice piece of equipment at a reasonable price that will add that extra boost that is often times needed.

Pros: Perfect size for smaller spaces, excellent sound, affordable price

Cons: No additional brackets or options for vertical mounting. If you have to mount this way the supplied velcro is not good enough in my opinion. The installer will have to be creative.


Michael M from Palm Springs CA on 2/26/2012

Crutchfield Customer Review (What's this?)

To start, I purchased a JVC KW-AVX 740 despite the negative reviews and installed it in my 2005 Ford F-250 SuperDuty. I was quite happy with it until I went to adjust the EQ and discovered there was hardly any bass at all. Frustrated, I called Crutchfield and described my delima. The representative asked what I was looking for and I told him "without spending a lot of money, I just want something to give my system more bass". He immediately recommended the SO B-8PT. At the time it was on sale for $159.99 including an amp wiring kit. I was shocked to hear the difference, the range and the overall sound this little powered sub-woofer put out. I mounted it on the back side of the rear folding seat, ran all wiring as instructed and mounted the remote control unit in small compartment on the drivers side of the dash. I would have paid $259.00 for this unit. The remote control lets you adjust the bass on every song you play with total ease. All adjustments on the unit itself are easy to adjust also when setting up. Believe me......this 13" X 9" box changed my JVC's rating from a 3 star to a 5 star rating hands down!

Pros: Ease of adjusting once installed, driver accessible remote control for instant bass adjustment. The range of adjustments and intense bass for such a small unit.

Cons: Depending on the skill of the installer and the type of vehicle it will be used in, the installation might take some time.

I added this to my factory stereo in my 2007 GMC Sierra single cab, it would have fit under either seat but I chose to mount it behind the center console on the rear wall with a bracket I made. The installation was simple and it looks nice in the truck. The sound was great out of the box but after tweaking it for a few minutes it sounds awesome. I have had lots of add on subs mostly Bazooka tubes but they take up too much space, this thing takes up hardly any and sounds better than the Bazookas. I am glad I took a chance and purchased this.

Pros: Easy install, takes up little space, looks nice, sounds Great

Cons: None as of yet.

bottom drops out

meh from Smallville, KS on 2/19/2012

This is a very mediocre sub. I've had it for a few months now and it has its ups, but not downs (more later). It does give a fairly nice low end punch for cars with little low-end in their stock systems (like mine). If you've got 6X9s or even 6.5s with good low end presence and bounce, then don't bother with this sub, it won't add much. My car has paper cone 6s all the way around and no real bottom end, so this sub helps. Here's the problem. The bass on this thing isn't really tight or bouncy, it seems loose and flabby, which might not be so bad except for one thing. And that is this - the bottom end drops out. I'll be listening to some jazz with a nice walking bass line and then suddenly the bass line walks right under the frequency cutoff and it disappears. Another great example - Stronger, by Kanye West. Right as the bass line steps down to the chorus it just disappears right off the deep end. The low rumbling of the chorus, the best part of that song, and alot of pop songs, just goes away. Very frustrating. The frequency response is listed as 40-200hz, but this just doesn't seem to be the case. Anyway, overall I guess it serves it's purpose, and I like having some low-end whereas before I had basically none. If the bottom didn't drop out on this thing it'd be four stars, and if I could tighten it up a bit more it'd be five stars. As it is, three stars is the ceiling on this little sub.

Pros: Compact, adds decent low end.

Cons: Bottom drops out, low notes disappear. Bass is flabby, not tight and bouncy.

Crutchfield Customer Review (What's this?)

Very Nice compact all in one unit, Fits nicely under rear seat of my 2004 Chevy Colorado quad cab. I was looking into a custom box amp and sub, but too much hassle trying to find what I wanted, that would fit without spacing my seat, or modifying anything. I came across this unit. the reviews were good, and it was all in one with a good warranty. So I thought I would give it a try. It was exactly what I wanted. It fit perfect under my rear seat with no modifications to the truck. The sound is incredible, Be patient until you have it tuned just right, once you have it set up, you will be extremely happy. I love the bass knob, for quick adjustment at your fingertips. I would recommend this for anyone that has limited space for a box and subs, You will not be disappointed. I will definitely buy another product from sound ordnance, they have their act together. And buying through Crutchfield, and getting the free install kit was just an extra bonus.

Pros: Everything

Cons: Nothing

Sounds good in F250 Crew Cab

UW Mitch from Banks, OR on 2/17/2012

Crutchfield Customer Review (What's this?)

For the price and size I was pleasantly surprised by the performance of this sub. It didn't fit under either of the front seats in my 1999 F250 crew cab - motor for the power seat on the driver side got in the way and seat rails were about 1/2" too narrow on the passenger side. Easily fit under the rear seat - I mounted on the driver side because it was going to be easier to run power to it. It doesn't provide eyeball blurring bass like you might get from a sealed 10" or 12" box, but again, for the size and price, that's not what one should expect. Fills in the lower octave that is really missing from a system without a sub.

Pros: Cost, size, ease of install.

Cons: None if you have proper expectations.

great sub!

Crutchfield Customer Review (What's this?)

Works as advertised. Great, little unit. Extends low-end effectively. I have matched to other SO speakers in doors of Xterra, sound is very balanced. Will not shake fillings out, but does what one should expect for an 8" driver, in a slim box, with a 120 watt amp for the price.

Pros: Great looks, great price.


big sound small package

jeff from Lake stevens, WA on 2/11/2012

Crutchfield Customer Review (What's this?)

Read many great reviews on this little sub and decided to try it. Money well spent. Like many others have said, it wont shake the windows in your car. But if you take the time to try different locations in your vehicle and tune it properly it will sound amazing. Installed behind the rear seat in a 07 double cab Tacoma. I tried under the drivers side seat and it sounded good there to but decided to put it behind the rear back seat. I had the stock JBL system and this little sub is way better then the JBL sub. Very happy with purchase.

Pros: Big sound from a very small package

Cons: none


Mickey from Bronx, NY on 2/11/2012

Crutchfield Customer Review (What's this?)

Delivers extraordinary performance in my Crew Cab Nissan Frontier. Bob Marley has never sounded better

Pros: Compact dimensions, light weight, easy installation, great integration with head unit.

Cons: Lacks versatility in mounting options. Requires much tuning.

Nice little woofer

bw from Bowling Green, OH on 2/11/2012

Crutchfield Customer Review (What's this?)

It is small and certainly doesn't put out bass like a dual 12" box, but it holds its own. It adds just enough bass to fill my truck, but not so much that you can hear the bolts vibrate 1/4 mile away. It is a nice addition and fits neatly under my rear seats, out of sight.

Pros: Easy install, delivers good clean bass.

Cons: Some kind of mounting holes or tabs would be nice.


AntC from Oklahoma City on 2/11/2012

I have two of these under both front seats and they sound awesome! With both under my seats, they feel like they produce more bass than my 10's I had in the trunk. Part of it is probably because it's so close to me. I read other reviews with issues and I would bet that they have it out of phase with their current speakers. If it is, it will hardly make any sound at all or you'll get odd sounding mids.



Just-right-sub for what I was needing

Guyer from Aurora, IL on 2/10/2012

I went ahead and got a little crazy and installed (2) SO powered subs in my '05 Jeep Liberty Sport. (1) under the driver's seat and (1) under the front passenger's seat. Hook up was easy. I found (2) unused openings in the firewall, (1) on each side of the car. It gives the extra UMPH I was looking for to accompany my Sony DSX-s310btx head unit and the (4) 6-1/2" Kicker KS60. They fit nicely under my seats with a little modification. All-in-all I am a happy Crutchfield customer.

Pros: Sound quality, hook-up, tech-support

Cons: To much RCA cable in wiring kit, but not complaining. Will find a place to put the extra wires.

Outstanding product!! I was able to fit the sub under the driver seat without even removing it in my 2006 Honda Pilot! Small, easy to install, yet with amazing sound that more than fills the interior. Very good product! Highly recommended!

Cons: None

Wish I didn't purchase...

Marc G. from Waterville, Me on 2/10/2012

Crutchfield Customer Review (What's this?)

I bought this for my Mini Cooper due to space limitations. I was not looking for carshaking bass, just something to give a decent low to the system I added to the car. I am disapointed, the pioneer 3 way spakers powered by a jvc head unit put out more bass than this unit. Infact I had to put my hand over the speaker to tell if it was really working. Either don't go with a sub or buy something more expensive, this is not a value.



Great value for the price

GregB from Rhode Island on 2/9/2012

Crutchfield Customer Review (What's this?)

Installed in 2002 Ford Ranger w/extended cab. It is mounted to the face of the jump seat behind the driver's seat. (Did not install the remote adjustment knob.) I was looking for some extension in the bottom octaves not tooth-rattling low-end and this unit delivers quite nicely. Impressive output and clarity from such a small front-loaded enclosure. Very nice wiring kit included from Crutchfield saved me a few bucks on the installation. I have this unit paired with a Kenwood KDC-X995 which has very nice crossover, delay and EQ functions. 4-factory speakers replaced with Polk Audio - can't recall model#.

Pros: Audio performance, price, size.

Cons: None I can think of.

Fills the Bose bass void in my Tahoe

Scott from Sacramento, ca on 2/8/2012

Crutchfield Customer Review (What's this?)

I installed this in my 2004 Tahoe with the Bose system. It's a good sub, especially for the price. But to be specific, you'll get good punch from bass drums in rock songs and decent lows. But I probably need to tweak the crossover/gain because I find the mid bass freq's are (boomy) at higher volume. I also have it out of phase and left the stock sub hooked up so I might simply be getting too much mid base because they are working in tandem at those freq's. If you listen to rap and want to feel the bass, this won't do for you. I listen to a mix of rock, hip hop, metal, and pop and am very happy that I actually have good bass now. The stock Bose sub is just too weak for my taste but this sub does an excellent job replacing what the Bose sub can't do.

Pros: Compact, cheap, easy hookup, good punch

Cons: No lows

Lotta bump in a tight space.

EdK from Titusville, FL on 2/8/2012

Crutchfield Customer Review (What's this?)

I got this unit because I have very limited space for a sub in my 2006 Toyota Tundra access cab. I installed the sub in the storage space under the back seat. I then cut sections out of the carpet around the storage area and covered the holes with speaker grills. In spite of the good reviews, I was a little worried about the bass coming from such small size. I'm happy to say that I could not be happier with the performance. The bass output is tight and plentiful. Even though the sub is under the back seat, I can still feel the bass. Installation was problem-free and the quality of the unit is exceptional.

Pros: Great sound, exceptional quality. Fits in tight spaces.

Cons: None.

Just Ok

david from San Diego, CA on 2/8/2012

Crutchfield Customer Review (What's this?)

I'm not sure why there are SO many 5 star ratings here. This is an ok speaker. If you can install some good 6x9's with proper power (might need an extra amp) it would sound better. However, if you can't fit in good 6x9's this will help fill in the low end. Do not expect deep clean bass though! I'm not talking rattle the trunk loud but rather the clean lows you get from a larger enclosure (even truck box subs with a quality driver.) There isn't enough air in the enclosure for it to reproduce high quality bass and definitively not enough air to get into the low bass range. Again when I say Low bass I don't mean your neighbors can hear you from a mile away, but quality lows from music like top 40, piano, techno, hip hop and even country. I believe the best aim is at music like metal and guitar based music but if your looking for beats it just doesn't get low enough. It seems to play 120-250hz range best. I've spent many hours tuning the system (using tuning equipment) and to say it produces quality bass lower than 120hz is pushing it. Anyway it's a simple setup and adds some lows but don't expect it to reach into the lower sound range. Oh this is in my wife's ford focus.

Pros: simple setup. fits easily under any seat.

Cons: It doesn't go much lower than 120hz with quality. Not for someone listening to music with nice low beats or even with deep dynamic range.

Awesome powered subwoofer

Chris H from Richmond, VA on 2/7/2012

Crutchfield Customer Review (What's this?)

I had just finished the installation of the SO subwoofer and a Kenwood Excelon KDC-X396 and couldn't be happier! The bass and overall sound is much better than the factory system in my 2005 Subaru Impreza. The subwoofer fit perfectly underneath the passenger seat. After tuning the subwoofer and head unit to my liking, they sounded awesome. Don't let the 8" size fool you, there's plenty of bass and more to spare. It has more than enough bass for enjoying the genres of music that I currently listen to: rock, alternative, and county. Thanks Crutchfield for the great deals and included installation materials!

Pros: Compact size, excellent bass output, ease of installation and value!

Cons: None, this subwoofer was exactly what I was looking for!

This sub rocks

David C from Surprise, AZ on 2/7/2012

Crutchfield Customer Review (What's this?)

The Sound ordinace B-8PT rocks in my 2006 Nissan Frontier King Cab. Fits perfectly under the front seat. For the space in the cab, it thumps while I can still seat people in the back seat. There's a factory grommet behind the break booster on the firewall to run the + wire from the battery to the sub. Pull the factory one out and the one that came with the amp wiring kit fits perfect. I installed my sub underneath my drivers seat to the left side of the back seat air ducts. It fits in a countersunk contour in the floor board. I put the wiring connections towards the front and the adjustment knobs to the rear. t

Pros: Fits perfect under the seat in my '06 Frontier.

Cons: Remote knob does not stick with the supplied two sided tape. I wire tied it under the dash with it turned all the way up. I adjust the level with my head unit(Kenwood Excellon 395).

Impressive in small package

DanJ from San Diego, CA on 2/7/2012

Crutchfield Customer Review (What's this?)

I found value in the other reviews that this sounded great and was small form factor. I put this into a 2007 Honda Ridgeline and couldn't be more pleased. Like others have mentioned, it won't win any sound competitions, but for the cab size (quite big) in the Ridgeline, it provides solid, robust base even at high volumes. I have it installed with a Pioneer avh-p4300dvd head unit which has its own bass out (no cross over needed). Stock speakers + this small bass unit make for great sound for any type of music.

Pros: small form factor, easy to install and wire.

Cons: instructions could have been a little more explicit- but I had enough to get it done.

Get it

BillK from San Francisco, CA on 2/7/2012

Crutchfield Customer Review (What's this?)

If you have a place to put this and have no base in your system get this. Well worth it and makes a 100% improvement on your sound. Keep in mind you will need a direct connect to your car battery. I had to do a little research but got it accomplished with a profession look myself.

Pros: Sounds great, the right size for under a seat, simple.

Cons: Needs direct connect to the car battery so installation is required. Research how to install a base in your car. You will need the EFX amplifier wiring kit that Crutchfield recommends and make sure your stereo unit has a base out.

powered sub

Crutchfield customer from Denver on 2/6/2012

Crutchfield Customer Review (What's this?)

Sounds very good, adds the extra punch completly lacking in a stock setup. Also running 4 Infinity 682.9cf speakers, but this small 8in powered sub makes lots of bass. It will NOT rattle the windows but it will add all the bass an old fart like me needs...

Pros: Good sounding bass, very easy to put under a seat.

Cons: not much way to attach this to keep it from moving around.

Perfect for my needs.

Joe from Connecticut on 2/6/2012

Crutchfield Customer Review (What's this?)

I drive an '05 Honda Odyssey and the system this minivan comes with is lackluster at best. After about 6 months I added an Alpine amp 40w by 4 and replaced the speakers the speakers Boston Acoustics. The sound improved by 100% by making that change vbut was never fully satisfied because it never got good bass. I was not shopping for a powered sub but got the Crutchfield email on this and figued it's about time to try and improve this sound. The hardest part was getting the power sire to the battery (you think they made these cars nowadays to float on water with the lack of access to the front) so I hired a tech to drill out a hole for the wire and run it into the car and I did the rest. Since I already had the amp it was very simple to run the sub off of that. When I finally got it hooked up I was very surprised at what a difference this made. if the original amp and 4 speakers made a 100% improvement, by adding on this powered subwoofer the sound improved another 2 or 3 fold! Best investment I have made on the car so far. Well worth it and the 3 year warranty (and free wire kit) made the decision easy to make.

Pros: Sound, Price, free wires, Crutchfield support and warranty.

Cons: User guide / installation guide not good. I had to call Crutchfield to find out what some of the dials were for.

This products does as advertised. It adds rich bass to your vehicle and it is very flexible with the EQ controls it provides to get optimum sound. Don't be fooled by its size this thing is powerful, won't shake your windows but enough to satisfy. The best part is its size and ease to install

Pros: Compact size and good bass range that can be tweaked to your liking

Cons: Can't figure out how to make it shut off when the vehicle is off (it does have a manual on/off button)

Outstanding product

Patrick from Oklahoma on 2/5/2012

Crutchfield Customer Review (What's this?)

Big sound from a very small package. I have two of these under the backseat of my extended cab Sierra. They sound great. They are the only amped speakers in the truck and they compliment the stock, unamped speakers well without overpowering them. I can listen to anything from country to dubstep without making adjustments. I would definitely recommend these to truck owners.

Pros: Small package, easy to hide, installation is a breeze. Complete with both installed in less than an hour and a half wires hidden and everything.

Cons: If anything, Small enclosure limits reflex, but it isn't built for window breaking bass.

Fantastic addition stereo system!

KAJS from NC on 2/5/2012

This speaker is more than I expected. It adds more bass than I thought possible in such a small package. I placed it easily under the passenger's seat. It is physically completely unnoticeable yet adds the bass my system has been lacking. Excellent product!!

Cons: None

Consider the Facts

Solarray from Denver, CO on 2/5/2012

Crutchfield Customer Review (What's this?)

This does exactly what it claims, so don't even think it can go as low as a 12" speaker. It will extend regular speakers by a whole octave, letting you hear bass and drums that were not even audible before, but there is still audible bass below 50 Hz that doesn't come through on this 8" speaker. The specs say it goes down to 40 Hz, so they're not faking anyone out here. For the price, size, and ease of installation, it is fantastic. If you listen to Rap,though, you're going to be left wanting a sub woofer for your sub woofer.

Pros: Great medium low bass for the money Best entry level sub woofer for tight spaces

Cons: Not enough for very low end stuff, like 5 string bass or rap. Doesn't fill the car with bass, just the front seat. Gets you addicted to sub woofers, so now I'll have to spend over $500, and lose space, to get that extra low end.

Stop thinking, JUST BUY IT!!!

RJ from Tuscaloosa, Alabama on 2/5/2012

Crutchfield Customer Review (What's this?)

As said before, why this isn't the "customer favorite" at the top of the page is beyond me. This is an unbelievable product. I installed in my 2007 Trailblazer under the passenger seat (manual seat). Fit like a glove. The enclosure is high quality and seems to be very durable. The wiring kit being included makes this a PHENOMENAL value (Think, buy any other sub and you will spend at least $30 on a wiring kit). Yes, the kit is "only" a SCOSCHE but it is remarkably nicer than I anticipated. The bass you can get out of this little unit is remarkable. I have had it installed for a week now and I haven't had to turn the remote above 50%, with the gain on the unit already set at UNDER 50%. If you are looking to add bass to any system while retaining a factory look, and are not interested in all of the nonsense designs that are aftermarket audio products nowadays, sprint as fast as possible to your shopping cart. I could not be any happier with this purchase.

Pros: Compact size, attractive minimalistic design, sturdy metal construction, tremendous power output, user-friendly gain adjustments, included wiring kit, unreal value.

Cons: None. Legitimately None.

HakuJin from Chicago, il on 2/4/2012

Crutchfield Customer Review (What's this?)

So I needed something to put in my 99 Wrangler. This is small enough to push out of the way whenever I need it to be. Install was easy and was surprised on the amount of tuning buttons it actually had. While I was looking for something to move my mirror a little bit, I guess this will do. It does shake the mirror, but other reviews lead me to believe I would feel the rattle in the back of my throat. This is not going to compare to a two 12's or anything like that. But I will say it is a great blend of bass to supplement what was lacking in my jeep. So it has some good low and pound when it hits. Just don't expect to rattle the windows on the car next to you. I miss those days and with my next car I'll build the competition again. But for a vehicle with limiting space and no bass this thing works great. Be sure to tune it right or you won't get the full potential of it.

Pros: Small Easy to install Clean bass

Cons: Had higher expectations of bass(my fault though).

Shawn from Erie, PA on 2/2/2012

Crutchfield Customer Review (What's this?)

A pretty good product when you consider the size and price. The first one I received would not turn on (I am using the speaker level inputs)so Crutchfield sent me a new one right away. Even with the replacement it was necessary to run a wire to the remote terminal to get it to turn on without cranking the volume way up. It doesn't give me everything that I want as far as sound quality; I can't seem to get it set just the way I would like but it is acceptable. However,if you want a compact sub that is easy to install this is a good product.

Pros: Size, price, power, Crutchfield service

Cons: Had to run a wire to the remote terminal, the speaker level inputs are not sensitive enough in my opinion.

Adds the little bit of puch I needed in a tight spot.

Crutchfield customer from Raleigh, NC on 2/2/2012

Crutchfield Customer Review (What's this?)

When it came to putting together the sound system for the 1975 IH 200 pickup I restored, finding places to mount speakers became a bit of a challenge, especially when it came to a subwoofer. Since it is a singe cab truck with only 2 1/2" under the seat and 4" between the back of the seat the rear of the cab, my options were very slim. The Sound Ordinance B-8PT fit perfectly when mounted to the rear cab cover (after making some custom brackets) and added just the amount of punch I was looking for. Now in no way it this going to give you the same bass you'd get from a sealed box with 12's and a 1000-watt amp, but for the music I listen to, it added the bass my other speakers were lacking. The installation was a cakewalk and it was easy to tune to my liking. I've only had it in for a month or two, so we'll see how it holds up in the long run.

Pros: Compact Easy Install Adds bass that other smaller speakers are lacking.

Cons: None Instructions could be a bit more detailed for those who aren't very skilled with stereo installation.

Great addition for full sound

Derp from Lon Gisland, NY on 2/1/2012

The perfect addition to fill in the low end. Not going to give you a booming system, but enough to make it sound great. It fits perfectly under the front seat of my AMC Gremlin with room to spare. Sitting on the seat its mounted under is like the scene from the Howard Stern movie

Pros: Has enough power to make you rattle, but not enough to annoy the car next to you.

Cons: Would have been nice if it came with tie down straps instead of the silly velcro strip.

Sounds Great

James from Pittsburgh, PA on 1/31/2012

Crutchfield Customer Review (What's this?)

Before buying this, I read the reviews that said, "... it does not deliver thumping bass, but a clean bass." That is exactly what I wanted and those reviews were true. With that bass on, I can hear notes from my old factor speakers that weren't there before. This sub-woffer doesn't overpower the other speakers so all you hear is bass, it somehow accentuates the other speakers and rounds out the sound. It really sounds good. I highly recommend it. I put this in my 2000 Honda Civic as a Christmas present to my sons, who share the car. They love it. Installing it was a nice project for us and it turned out great. The free install kit and YouTube really came in handy. The only problem we encountered was that the sub didn't fit under the front seat where we were planning on putting it - it was too thick. If it had been a 1/2 inch thinner, it would have been perfect. (I didn't really measure the powered sub to see if it matched the demisions listed in the specs.) I would give it 4.5 stars (half a star off for being too thick).

Pros: Sound. Size. Value.

Cons: Not thin enough to fit under the front seat of my 2000 Civic.

Good Stuff. Recomended.

Pros: Works Great

Cons: Needs Better Mounting, eg... more robust wide velcrow would help.

I got this to put under the driver's seat and it is wonderful. I like to feel the bass and this gets the job done without rattling the windows; exactly what I wanted!

Pros: easy to install, works great and feels very nice; plus super helpful sales people in store (as usual).

Cons: if you're looking to disturb your neighbors or fellow drivers on the road look elsewhere (not applicable to me).

Perfect for 40 something who likes a little boom!

Bought this product expecting it to perform, but with tempered expectations for the price. After installing this in a 2004 Toyota Echo, under the passenger seat, I was surprised by the great sound this produces. What a great find. I will for sure buy a product by this brand again. Great product for the money. For an 8 inch woofer this puts out great sound, and is very responsive. Would definately reccomend this product to friends.

Pros: Price, ease of use, quality of product, Great sound.

Cons: No Complaints.

Amazing sound in a small package
