Great powered Sub for a really great price. Installed this in the truck of my nieces 2006 Civic. For a small car this would be a great addition if you can mount in the trunk.


Cons: None

Great integrated sub

Kevin from Huntington, WV on 6/8/2017

2011 Chevrolet HHR
Crutchfield Customer Review (What's this?)

Recently I inherited a 2011 Chevy HHR, which had a decent head unit and speakers, but the bass response was definitely lacking. Since the music I listen to (blues, classic rock, etc) doesn't require thumping, I just needed a basic sub added to my system. And I didn't want to run a separate Amp just for the sub. The B-8P fit the bill perfectly. I'm getting great bass response, the power rating is perfect for my system, and my music sounds great!

Pros: The price was right, great bass response, doesn't take up much room in the cargo area, and easy install. Recommend highly!

Cons: If you listen to bumpty-bump music and want your fenders and doors to rattle, go with something bigger.

Practical Bass

This just transformed my already good system (Boston and infinity's all around) to to a truly fulfilling system. Everything from Nat king Cole to slayer just sounds better! Its that simple, awesome product, awesome performance, happy customer. Just in the packaging alone you can tell how much the company cares about their product. Me and a friend described its output as practical bass, for performance music listening.



Outstanding little subwoofer solution!!!!

Anonymous from Seattle, WA on 4/26/2017

Crutchfield Customer Review (What's this?)

I installed this sub in a 2015 Honda Fit Ex that came with a 6 speaker factory setup. I also installed 2 Rockford Fosgate 6.5 coaxial speakers in my front doors. I have to admit that the install took much longer than I originally planned but a good portion of that time was my own fault. The sub, once installed correctly, is running above expectations and I'd actually forgotten how effective isobaric can be. I'm 45 years young and back in the day.... well, that's another story all together. The tech support I received from one of Crutchfields technicians "Oakley" was outstanding. I ran power from a T30 Torx bolt located at the fuse block instead of running from the battery terminal in order to save some time (my decision). I realize this isn't the best practice but I was trying to save some time and so far so good. I ran a ground wire in the hatch of the car near the sub and remote wire from the back of the factory Head unit to the sub. I also ended up running 16 gage speaker wire directly from the rear door speakers themselves to the sub, as I found splicing into the thin factory speaker wires at the bottom of the door pillars did not have enough power to drive the sub. I also found the colors of the speaker wire and polarity misleading on a couple of different sites, including what Crutchfield had on file for this car. Both rear door speaker wires were blue (positive), and pink (negative) for both doors. You can't beat a sub under $100 so don't hesitate this sub!

Pros: Price, efficiency, size, craftsmanship, perfect for filling in that low end sound in a small car.

Cons: As others have mentioned, the lack of a remote control for turning up the gains. This can only be done from the rear of the unit but that was clearly stated the descriptions so net a big deal. At this price point I can't complain.

Great all in one package!

Brandon from Illinois on 4/26/2017

Crutchfield Customer Review (What's this?)

Sounds 100 times better than i expected. If you want to add some bass to a system without spending a lot this will do great. I replaced 2 10" memphis subs with this and am not dissapointed at all. The only place this will let you down is in the lows. But it is an 8" so that is expected. But for anything other than rap music this thing is well worth the money. I do have an aftermarket deck so i have more control over it. I have a 4 door sedan and it still rattles the rearview mirror.

Pros: Best bang for the money. Takes up little space.

Cons: None

Perfect addition to a factory audio system !

Tulasiram from Torrance , CA on 4/25/2017

Crutchfield Customer Review (What's this?)

This 8" sub won't rattle your car & won't shake your windows but definitely improves the listening experience by adding ample amount of bass. I absolutely love this product. I've added this sub for my 2016 Mustang Coupe factory audio system. This doesn't take much trunk space & has bass adjusting level at the back of unit.

Pros: Crutchfield Customer Support. Let them know if you don't know what to buy and has budget constraint. They'll get the right choices for you.


Great powered sub

Jeff from Longview, WA on 4/10/2017

Crutchfield Customer Review (What's this?)

Just a fantastic solution for my van. Installed a Alpine CDE 164BT head unit and Alpine type R speakers first. Something was just missing. Added the powered sub and now I have all the low-end anyone could need. Feature-rich sub-woofer and it sounds great. I think next I'll add the Alpine KTP-445A power pack and some Dynamat to the doors and my sound should be about as good as it gets for a conversion van. My B-8P has a on / off switch for the LED lighting in the bottom left corner, next to the fuse. Nice added feature I am guessing is new.

Pros: Great feature set and really good sounding powered sub at a steal of a price.

Cons: None I can think of.

Good bass for a low price

I purchased this for my son as a Christmas gift and finally installed it in March. Hooked it up to the factory stereo in a 2004 Nissan Sentra. Sounds really good for the price. He is really happy with it. We used heavy duty Velcro to keep it from sliding around.

Pros: Sounds good for the price.

The little eight inch sub does deliver a great sound and exactly what I was looking for. The thing delivers a great punch of bass in the cabin of my car and I always come back to Crutchfield they always have what I want at a great price. I also now have extra light to look around in my trunk for the junk at night as the sub has interior lights installed that is a great feature to have. Thank you Crutchfield.

Pros: Great Sound, size, and price.

Cons: Slides around in my trunk.

This sub does what it's supposed to and more! This thing pounds and sounds great! If your looking to add bass but don't want 2 12's, this thing will do justice. It looks great as well.

Great Little SUB

Chris from Marcus Hook, PA on 2/22/2017

Crutchfield Customer Review (What's this?)

Excellent Value for the Money. Built well and looks nice without being over the top. Bought Jensen 6X9's and a Pioneer Amp from Crutchfield and needed a bit more bass in my Buick. I have the Sub's level control set to 50% and it does a super nice job filling in the lower frequencies. 100 bucks with free shipping makes me feel like I stole it. THANKS

Pros: The review says it all--Excellent Value

Cons: Wish it had a separate level control so I could adjust it from the driver's seat

Pounding Bass!

Chris from Paramount, CA on 1/26/2017

Crutchfield Customer Review (What's this?)

Excellent Product. The bass is awesome and sounds like you have a 12inch in the trunk. I hooked mine up in my G37 and I love it.. Highly recommended.


Cons: nONE

I would recommend this to a friend

Jose A from Los Angeles Ca on 1/22/2017

Crutchfield Customer Review (What's this?)

Bass quality is surprisingly good. I have the gain turned up to just a little less than 3/4. Using it in a 2011 2 door altima with stock head unit, bass set at "0" and the sub sometimes drowns door speakers (aftermarket ) level remote would have been a nice option even if it was offered as an accessory. In my opinion, enough to feel the bass inside, but don't expect to shake house windows or set off car alarms. Over all, well worth the money. Would recommend if you just want to add a little extra to your system.

Pros: Small, ported, stylish and economical

Cons: No remote level option

Aarron from Meadville, PA on 1/12/2017

Crutchfield Customer Review (What's this?)

Great product for the price! I have a 2001 Mustang as my daily driver, and it has the dreaded Mach 460 system (the speakers are 8 ohms so not compatible with replacement 4ohms speakers - in order to replace them you would have to bypass the factory amps and perhaps get a replacement amp). I replaced the head unit a few years back which helped, but wow - adding this sub accented my current system so much so that I now don't feel that I need to replace the components - at least for now. Don't have super high expectations for a self-powered woofer, and you won't be disappointed. If you're looking for something that adds a little punch without spending a fortune (and a lot of time installing) - this fits the bill!

Cons: Should include Velcro for the bottom

Crutchfield Customer Review (What's this?)

A lot of sound from a small, convenient, and affordable package. This B-8P will not rattle your windows with neighborhood waking bass, but it definitely packs a small punch and fills in lows nicely. Installed in '03 Volkswagen GTI using Pioneer DEH-X8800BHS head unit.

Pros: Sounds great, affordable, doesn't take up much space, easily removable, sub lit by white LEDs

Cons: Lower range bass notes are very muted

This sub is an amazing deal (steal?)! Great sound and a simple install without having to worry about a separate amp. This really filled out the sound in my Impreza, and has a made a huge difference compared to the terrible stock system. Awesome performance vs. price! Also kudos to Crutchfield support for providing the correct color code of the rear speaker wires to ensure the polarity was correct. Very happy customer!

Small bass big sound

jason from Mount Vernon, IL on 10/23/2016

Crutchfield Customer Review (What's this?)

Put this in a 2016 regular cab ram with a Kenwood head unit. Still have the factory speakers that sound okay for now but needed a little more bass. I'm 47 so I wasn't looking for a 1000 watts. This worked really well to fill the void, with the space behind the seat it has to stay upright and not lay flat which is kind of a bummer. Overall happy with the purchase though.

Pros: Great sound

Cons: Little big behind the seat

Firstly, remember, this is "only" an 80 watt sub. It easily fit in the trunk of my sons '99 Mits. Galant and rattles the interior, but in a very, positive way. We also replaced the rear deck speakers with Pioneer TS-A6966R and the sound/clarity increased exponentially.

Nice bass

Michael a from St Petersburg, FL on 9/20/2016

Crutchfield Customer Review (What's this?)

I have had many systems before and just wanted to add a little bit of sub to round out my new system. This box was easy to install and really hits when needed. It hits so hard I turned it down. Great buy for the money. If you want a lot of bass I would go up to a bigger woofer size, however if you want a little bass to round out a system this is perfect. I put it in a 2007 Honda Civic and its perfect.

Pros: Great price, perfect if you have the highs, and mids already and need a little bass. Plays my dance music, rock, and other music fine

Cons: If you like a lot of bass I would get a bigger sub woofer as this is not a ton of bass. great for small systems or for smaller cars.

Surprising sound!

Adam from Covington, KY on 9/8/2016

Crutchfield Customer Review (What's this?)

Wow... This thing sounds awesome! I went in knowing that this type of enclosure gives you much more powerful sound but I am surprised that its about as good as my old Rockford 10" without the bulk and in my '08 Mustang, it fits perfectly behind the wheel well. The materials are all very nice as well from the sturdy glass window to the soft carpet and metal backplate. The only reason I couldn't give it that fifth star is because the sub was mounted in offset to where the brand text is not centered and it's very noticeable. It's a shame because it has the lighting and such. Another issue is with one of the knobs on the rear being bent but still functions as it should. Overall I'm very impressed for the price. I would definitely buy it again...

Pros: Overall build quality and sound was above expectations for this price point.

Cons: Missed the fine details.

Simple and perfect!

Mikey from New Jersey on 9/3/2016

Crutchfield Customer Review (What's this?)

If you want to shake the neighborhood, not for you. If you want just enough bass for yourself, look no further. I purchased this amplified sub about 7-8 years ago. She's been with me since my first 96 jeep Cherokee sport. Moved her to my dodge till the engine blew and stored her when I had my Honda. Just recently pulled her from storage and installed in my 2012 liberty and I'm glad I never got rid of her. This little powered box is the bomb. Perfect clear bass and super easy to install every time. The price is unbeatable. I will say having it in a car trunk is not as good as when it's in a truck trunk. But if you own a trunk and want some extra bass without spending a lot and easy installment, this sub kicks ass!!! After almost 8 years And 3 vehicles she kicks like the day I bought her. Definitely recommend! No head unit change required if you don't want. Just buy a high/low converter with a built in trigger and your set!

Pros: Super durable Kicks clear and perfect Good size Super easy installment Awesome price

Cons: Not as good in car trunk as truck trunk

great product for the money

Jay H from south jersey on 9/1/2016

I purchased this and installed it about 3 months ago in my Silverado extended cab with a Sony head unit with RCA outputs and built in high pass and low pass filters. This head unit puts out 15 watts RMS per channel. I have this coupled to four 5.25" speakers. I have the sound ordnance sub mounted between my front seats to replace the jump seat and it makes a great armrest as well. The performance fits perfectly with the rest of the components. Great low end fill. Performs better than I expected.

Pros: Great value

Cons: None

Save your money, if you want big bass...

Box bangs for a discount brand

Jim R. from Killeen, TX on 7/5/2016

1998 Ford Escort
Crutchfield Customer Review (What's this?)

This little band-pass box bangs. No, it's not a Kicker SoloBaric so you can't expect results like that. But for a discount product line it serves it's purpose. I have zero regrets purchasing this little sub after a few weeks. Maybe it won't last as long as a big name brand, only time will tell. But for the $100-ish I paid it has enough value to dollar for me. I'm not using it in any SPL contests or to out do the guy next to me with the $3k setup. I simply wanted to add just a bit of thump to a replacement system in a beater car that gets driven a lot. I paired this powered sub with a JVC media head-unit that has a 4.0v pre-amp output and there are no issues. I read some reviews where people claimed they had no increase in bass response so I was a bit nervous about the purchase but my concerns turned out to be unfounded. All I can think of is those other consumers paired this with a head-unit with a very low pre-amp voltage output and/or didn't understand how to configure gain settings at either end in addition to the other settings options.

Pros: Very good value for the price point, Inexpensive, stable installation without permanent mounting, easy 4 connection wiring, ability to enable or disable the subwoofer light, sub works well and can add a legitimate amount of bass to a system for anyone not looking to win an SPL contest.

Cons: Being an off-brand it may not last as long as name brand equipment, power and response are not that of the more expensive name brands (but again you're not paying the same price)

Pleased with the purchase

1999 Volkswagen Beetle
Crutchfield Customer Review (What's this?)

The bass fills the small interior of the beetle really well. For as loud as it sounds inside the car I was pleasantly surprised its not loud outside the car. I would recommend this sub for anybody that wants good bass but isn't looking to be felt in other cars while sitting at stop lights.

Pros: Can install disconnects to make the sub quick and easy to remove if the space is required for moving larger objects.

Cons: None so far.

Amazing low end filler for the money.

James P from Chicago, IL on 6/13/2016

1998 Chevrolet Suburban
Crutchfield Customer Review (What's this?)

Bought this to use as a low end filler. No disappointments whatsoever and it can really thump if asked to although I dont. I have a utility suburban so its cavernous behind the front and only seat so placement was no problem. BEWARE: Crutchfield recommends 8 g power supply wire generally on the website. This 80 watt unit is only 7.5 amps. 8 g wire kits with maxi fuses do not accept anything less than a 20 amp fuse. The 8g supply is overkill for this particular unit. 12 g with a conventional fuse holder is more than sufficient to install this unit. I now have to rewire the supply line as I do not feel comfortable using a 20 amp fuse. I would also add that Crutchfield tech support said the 20 amp fuse was ok....which it really isnt in the event of a frontal impact or anything that otherwise may short the supply or audio wiring. Great buy for more than sufficient bass.

Pros: Great value, more than sufficient low end filler.

Cons: Surprising misinformation from both the Crutchfield website and tech support.

Crutchfield response on 6/15/2016 Thanks to this informative review, one of our Tech gurus, Daniel, reached out to James to let him know we have created a new amp wiring kit for applications just like this, and we've added it as an accessory to this powered Sound Ordnance subwoofer. Thank you, James.

Crutchfield Customer Review (What's this?)

I purchases this for my son and was not that happy with it. The sound, while clear, is not as powerful as I had hoped. I feel like it lacks hit that a subwoofer should have and served more as an expensive amplifier than a subwoofer. After having it for 5 months, we are in the process of selling it and upgrading to a more powerful and effective sub.

Pros: Small, good sound quality

Cons: Not very powerful

Crutchfield Customer Review (What's this?)

Wow, got this for the daughter's car as a Christmas gift. Was looking for something compact and not to radical since it was going in a 1999 Escort Sedan. The car was equipped with a Sony X-plode head unit and Kenwood speakers. This sub really filled the void in the bass and hits really, really well. It we were not looking for anything that rattled the car or was annoying to a nearby car in traffic. But honestly, this little powerhouse could do it with the gains settings ramped up! It is not used for that and provides a nice, compact all-in-one good looking sub. Will be purchasing another one here soon for the family car!

Pros: Sound Quality, appearance, cost.

Cons: None

Solid Product

Christian from Campbell, CA on 1/19/2016

Crutchfield Customer Review (What's this?)

For the money this is a great product! It was one of the cheapest powered sub woofers I could find, but it didn't disappoint. There is a very similar one available on another website, but I decided to go with Crutchfield because of their customer service and return policy. But after installing it and listening to it for a few weeks on an assortment of music, I won't be returning it. I have a Nissan Versa hatchback, and this thing fills out the lows very nicely. It does not hit the very low frequencies, unfortunately, but it will make almost all music sound better. A lot better! I thought about getting a 12" subwoofer to hit the very low frequencies better, but I didn't want to spend $80+ dollars more. I'm very happy with it...for the money. Turn the gain up and the bass becomes overwhelmingly strong!!

Pros: Cheap Loud

Cons: Very little LOW (20-40mhz) frequency response Package lists 50 watts RMS, 100 max.

Great Sub!

JWC from Arizona on 12/21/2015

Crutchfield Customer Review (What's this?)

Installed this sub in my 2004 Nissan Frontier extended cab to round out my sound. I am very impressed. I was a bit skeptical about the band-pass enclosure but it makes all of my music sound great. From rap to pop to rock and metal. Double bass blast-beats sound just as good as the 808 drops. You're not going to wake the neighbors with this one, but it sure as heck will fill the cab of your truck or your small car with pretty clean bass for the money. Installation was a breeze and the available adjustments are nice. I'm using my head units high pass filter to keep the base out of my door speakers and pilla i'm using my head units high pass filter to keep the base out of my door speakers and The tweeters in the pillars. I have the low pass filter on the subwoofer set to 200 Hz. I love that they put an on/off switch for the LED lighting. I can't really see it anyway, but it is a nice option.

Pros: Great sound for not much $. Easy install and versatile sound.

Cons: If you're looking to wake the neighbors or get the attention of the girls in the car next to you, this isn't the sub for you.

Great shopping experiance

Good quality of item. Very happy with my purcuse. Everything encluded. The help before buying was fantastic. Had no need to ask for help after buying. All was explained with no issues.

Pros: Great subwoofer sound

Cons: None

Excellent 8" subwoofer for a great deal.

James from Wisconsin on 12/7/2015

Crutchfield Customer Review (What's this?)

An awesome subwoofer that produces excellent bass for only being an 8" sub. Just finished installing it in my 1998 Honda Accord with a Pioneer radio, and I couldn't be happier with how it all came together. Highly recommended if you have a smaller car or just want a subwoofer that gives you good punch but doesn't rattle the windows.

Pros: - Great bargain for the sound quality. - Helpful pictures in the instructions for setup. - Small sub to leave space in the trunk.

Cons: - Absolutely none!

Solid bass from a small enclosure

Crutchfield Customer Review (What's this?)

I installed this unit in my 1999 Ford Explorer2DR Sport, to compliment the new JVC stereo and speakers I had also purchased from Crutchfield. The bass from this very reasonably priced unit fills my interior, but does not rattle my body panels. I am very satisfied with the performance, quality, value and ease of installation. I would buy this subwoofer again and have already recommended it to a friend.

Pros: Ease of installation, big bass from a small unit that does not take over all your free space.

Cons: None so far.

Crutchfield Customer Review (What's this?)

This little thing packs a punch! No it isn't as window rattling as most are looking for, but I just hooked this up[ in the 99 Firebird and couldn't be happier. Just enough thump to be noticed, but not obnoxious. It may take a little time to adjust your individual settings, but all in all i couldn't be happier. Putting the other one in the suburban tomorrow.

Pros: great price, smaller size, fits most anywhere.

Cons: none at this time. for the price, you can't go wrong!

Good with stock radio. GREAT with aftermarket receiver!!!!

Jon W from Michigan on 8/2/2015

Crutchfield Customer Review (What's this?)

I bought this sub to add to my stock monsoon system in my 2006 Grand Prix. I got the audio signal through a line out converter. I really liked the bass that is produced but sometimes the bass seemed distorted. A couple months later, I got an aftermarket receiver for my birthday. I installed the new receiver and got rid of the line out converter and connected the sub directly to the output on the back of the receiver. All I can say is WOW!!!! The bass that is now produces is absolutely amazing!!! No more distorted bass and it sounds great!! I would recommend this sub to anyone!!



Great bass, great price

Dave B from Chicopee,MA on 7/4/2015

Crutchfield Customer Review (What's this?)

I purchased this to give some low end to the sound in my full size work van. I was very pleased with the depth in the bass. I was able to get the sound I wanted with minimal adjustments.

Pros: Great price for the sub! Great sound!

Cons: This was placed behind the passenger seat. Not a lot of wiggle room due to cage behind seat. If it was a little smaller in depth,it would allow the seat to be moved back a little more.

Stunning Performance and Vaule!!

I don't not usually buy audio electronics online, I perfer to listen buy. But I couldn't be happier with my purchase!! The sub arrived in 2 days!!! The sound that this little monster generates is simply amazing for $119!! Solid powerful bass that is surprisingly deep and accurate. In a well made tidy package! Don't hesitate, just buy it! It's one of the best purchases I have ever made!

Pros: Deep strong bass, small size and we'll made!

Cons: None as of yet.

Bought this to fill in lows on a BMW E46 4dr and save trunk space. It does the job with a great quality box... Not exactly gonna rattle the dentures out of my neighbors but sounds good. Maybe if I hook it up to an aftermarket radio it will come to life but for now I'm happy with it.

Pros: Takes up very little trunk space Good Quality box Easy to hook up Sounds good without any distortion

Cons: Packs bout as much punch as a factory sub

I bought this for my wifes 07 camry and she loves it! It is the heart of the system bringing it to a level of a high end stock stereo. Cant beat the price and easy to install for the diy person.

Great value! Great product! Great Price! Not gonna win any sound competitions but it will provide great low end to any vehicle. Had mine installed in my wife's 2010 Versa. Sounded great with the factory stereo and not over powering the highs. 5 star review!

Cons: Wish they listed a 12" version lol

Mother of Bass!

sotto52 from Arizona on 2/5/2015

Crutchfield Customer Review (What's this?)

Stop debating about other powered sub enclosures. I dropped this bad dude in my wife's Toyota Highlander and holly crap did this thing surprise me. For it being only a 8" sub, it sounds like a 12" and the enclosure is very nice on the eyes. The illumination feature is merely just a white light that lets you see in the box, not a colored one in which I thought it may be. Anyways, instead on buying a separate amp and sub enclosure this thing made it easy. All you need to do is wire the amp kit and plug her in, presto! I will come back and upload a you tube video for everyone. The you tube videos I watched really didn't do it justice, but they did help a little. The quality sound it produces for under $150 is outstanding. This will make any music super fun to listen to for fractions of the price. That is all, I'm going outside to go sit in the car and jam out.

Pros: Sound Quality; Price tag; Small in size, not in sound

Cons: I would have preferred a side mounted amp connection vs. rear input

Great product

Joe from Scranton, Pa on 2/5/2015

Crutchfield Customer Review (What's this?)

Love the product, works great and for a great price. Delivers a deep bass without distorting sound. Only problem with it is that the directions for tuning the sub are difficult.

Pros: Great sound, good price

Cons: Tuning, can get a cheaper wiring kit online

Good deep sound

SG from Durango, CO on 1/23/2015

Crutchfield Customer Review (What's this?)

I installed four new polk speakers and a Pioneer receiver to replace the stock system on my 13 silverado crew cab. I waited with the sub install because I forgot to order the wiring kit for it. The polk speakers sounded awesome, good all around sound. Clear and sharp. Then I added the subwoofer and holy smokes! This thing adds a whole new dimension. Adjustability is great. Classical music sound heavenly and Metallica rocks out!

Pros: Sound, ease of install, sound.

Cons: Size. Does not really fit my truck, but I sacrifice a bit of rear seat for great sound!

Great low end for the price

Brian from Oklahoma City on 1/20/2015

Crutchfield Customer Review (What's this?)

Bought one of these three years ago for another vehicle and sold it when I sold the car. Just bought another one - the Sound Ordnance B-8P - for my 2012 Civic and love it all over again. This time I am using with high-level inputs from the rear speakers and the low end is excellent. Really completed my factory sound system. install took about 30 minutes. Love it once I got all the levels and settings all tuned. Excellent!

Pros: Price, fit and finish, value, LED lighting

Cons: Not a single one

Firefighter from Washington on 1/11/2015

Crutchfield Customer Review (What's this?)

For the price I cant imagine a bigger improvement in my trucks sound. It was a straightforward installation. Not easy, not too hard. It took me about four hours. I was disappointed was I first fired it up. Then I started to play with the sound controls. When I got the crossover set right it opened up the sound. I think it took over the lows that my six inch speakers were having trouble making. All in all a great buy.



Awsome sound for an 8

slippysauce from Utah on 1/6/2015

Crutchfield Customer Review (What's this?)

I cannot believe anyone would give this product anything lass than 5 stars, I have owned JL audio, Rockford Fosgate, MTX, and Kenwood sound systems, that were all fantastic, the reason I tried out sound ordinance out was because of the great reviews that people left. My kedwood system was stolen out of my car and I didnt want to go to the expense of replacing everything, so I put a sony xplode stereo in and this Sound Ordinance powered sub in, I figured for the bucks I paid for the sub was well worth it, I already had the wiring that was the only thing that survived the theft. I have always has a stereo system of some sort in every vehicle that I have ever owned. I was completely surprised by the bump I got out of this 8" sub. I have it in the trunk of my 2000 ford escort and it sounds amazing.

Pros: Price, sound, and great quality

Cons: none what so ever

Not loud enough for me

Drennen from United States on 1/6/2015

It was okay, built solid, easy to hook up. I wished it had a remote for the volume level. The bottom line for me is that it could not surpass the bass from my door and rear deck speakers. It was about equal. So I am returning it. If you have very little bass in your system currently, this would be an affordable improvement. If you have large door speakers and 6x9 deck speakers like me, it might not be able to really add to that. Probably need a 12 and 150+ watts.

Pros: Solid, high quality construction. Attractive

Cons: Its still an 8" sub. Which for some people, will not be enough.

Good little sub

Benjo from Concord, CA on 1/4/2015

Crutchfield Customer Review (What's this?)

Good little sub to fill in the lows. This is not the sub that rattles your windows and pounds your chest but it gives your sound system the bass that is lacking from the door speakers.

Pros: Well constructed, solid and provides adequate bass. Compact.

Cons: The plexiglass look makes it gimmicky, I guess it appeals to the younger crowed. The 8 inch sub does not provide the boom that you maybe looking for. Should provide better documentation in tuning the sub

This is a good & powerful little subwoofer set-up. Perfect for an add-on. Had other kids at my daughter's school ask if I wld install one in their cars. Also had a tint shop guys ask about it so he cld order one

Pros: Easy hook up, sounds great


sub for outlook

Nate from southeastern Mass. on 1/2/2015

Crutchfield Customer Review (What's this?)

So far so good. This was purchased to fill in the lows for a new setup in Saturn outlook. Definitely not put in to shake the mirrors off the car, for filling in the music and adding the punch and fill the 6 1/2 door speakers can't handle cleanly, it performs very well. Having the amp internal makes removal when I need the cargo space a breeze!

Pros: All in one design makes removal when I need space easy. Fills in music very nicely and price is reasonable

Cons: So far is doing exactly what I bought it for so closes to a con I have is my teens want enough base to blow the windows 8 won't do that.

Good speaker!

Sound ordance B-8P from Hester, louisiana on 12/17/2014

Crutchfield Customer Review (What's this?)

Nice speaker for how small it is!

Pros: Hits really good highs. The speaker is only an 8 but dont let the size of the speaker fool you!

Cons: Doesnt hit lows, but i didnt expect it because its only an 8".

Awesome, but takes time to install

Spencer from Georgia on 12/13/2014

This sub woofer and amp combo is a beast, and as everyone has said delivers solid bass. I am a teenager and I think this is fully sufficient for the bass heavy music these days. You will definitely feel that vibration, but without it vibrating your entire car, which I think is ridiculous. Also, if you do want it to shake your whole car,,, you're going to have to increase your price range a couple hundred dollars. Also note that you cannot expect to install this yourself in a quick period of time unless you are experienced with car stereo systems. I have never done anything with stereo systems, and I decided to fully re-do my '96 Jeep Cherokee's. I got this sub, 2 new Kicker speakers, and a Clarion head unit. All of these took me a total of about 10 or 11 hours to install, but in my opinion, is totally worth saving the money for somebody to install it. So what I'm trying to say is, you will run into problems, blowing fuses, missing wires, missing tools, etc. so just know you're in for a ride installing this and possibly a whole new stereo system, but I found it fun and so satisfying at the end when you get that feeling of "I FINALLY finished". Would totally recommend, even though it is somewhat a hassle to install.

Pros: Great bass Great price (you won't find a better deal for a sub and an amp) Don't have to buy or install a separate sub and amp Looks nice

Cons: Takes a while to install If you want a crazy sub that shakes your entire car, this isn't the one for you

Crutchfield Customer Review (What's this?)

Installed in my 1998 camry. I hav a 9month old son so I need to fit a stroller into the trunk. I didn't want to get this Sub because I was scared nothing was gonna fit. But when it came in and I installed it, I had plenty of space in my trunk for groceries and the stroller. The sound coming out of my trunk is amazing! Raddls the back when I want it to. Sounds perfect and add plenty of bass to my car. Sounds nice and clear and not messy at all. Very happy with the price and sound of the sub and it was a perfect price for me.

Pros: Loud Doesn't take up too much room Good bass Is stroller proof Heavy duty Built to last Amazing sound Perfect for small trunks

Cons: None so far!

5 Stars All The Way! I did a lot of research before coming upon the 8-BP. Bottom line...This purchase was excellent! A sturdy, well made, powered sub! You could not build a box of this quality and sound for the purchase price. Rich bass, high and low. I have two 6x9 Pioneers and the 8-BP in my Nissan Frontier and the sound is fantastic!

Pros: Sturdy, well built enclosure. Powered! Ready to go, out of the box!

Mike from Texas on 11/24/2014

Crutchfield Customer Review (What's this?)

Excellent build quality, good controls, looks really nice too. The bass is def solid inside the vehicle, but dont expect it to shake the neighbors windows! Install was done on 2013 JKUR wrangler using an audio control LC2i since the stock "top of the line" Jeep radio has no preamp outputs and totally rolls off bass and volume when cranked up! Def a huge improvement over the OEM subwoofer (which is a total joke).

Pros: Quality build, good sound, small footprint

Cons: None to speak of

very satisified

Robert O from Minneapolis MN on 11/19/2014

Crutchfield Customer Review (What's this?)

For the money spent I am very satisfied with the Sound Ordnance 8" powered sub. It's exactly what I needed to fill in the void in my system. This sub will not blow out any windows but the sound is great, powerful and more than I would expect for the size and retail. Hook up was a breeze since it was an "all in one" system. I was surprised how many more negative reviews or unhappy reviews there were on much more expensive powered subs.

Pros: wallet friendly, easy to hook up, great bass production, sub box looks good and appears to be well built

Cons: No owners manual or directions on installation and suggested crossover settings. The sub box takes up allot of room. All in all many more pro's than con's!

5 Stars!

Pros: Easy installation. Good sonics.

Cons: The price is rather steep compared to competitive listings.

great bass for your buck

Jason from Hope Michigan on 11/13/2014

Easy hook up, low power draw, and good low frequency sound from a very small space. This sub requires a little experimenting with placement for the best sound. Turned one way its barely noticable, faced the other way it sounds like two eights in a sealed box with more than 80watts rms. I got an open box model at a discount and couldnt tell it had ever been opened at all. Would recommend

Pros: Cheap small good sound seems high quality

Cons: None

Crutchfield Customer Review (What's this?)

Was looking for something to fill in the low end of my system ( pioneer head unit and polk db speakers ), I was a little worried that it wouldn't be enough to do the job in the trunk of my 2012 malibu., but after reading many reviews and talking to rusty at Crutchfield, I decided to try it and was very happily surprised, it was easy to install since I had an infinity bass link before and it doesn't take much trunk space, now I can turn my stereo up very high and everything is very clear, I was also happy with the long warranty and low price. Depending on what you want, personally I don't think you can go wrong with this sub. Thanks again Crutchfield!

Pros: Very good sound from such a small sub, space saving and budget friendly

Cons: None yet

Crutchfield Customer Review (What's this?)

These things are great! I put one in my wife's car ('97 4Runner) along with a set of Kenwood separates in the front doors. The sound difference is amazing. The new speakers in the door work for the highs and mids, and the sub just rounds out the sound. I can't believe what I have been missing all these years. Bass makes music that much more enjoyable. My kid was so impressed with the sub that I got him one for his 18th birthday. He has Sound Ordnance 6 1/2" speakers in the front and rear of his '96 Jeep Cherokee and it sounded good before but now it sounds really good with this sub. I highly recommend this sub, its is a great bang for the buck. It is fairly easy to dial in and it sounds good. For that matter, the Sound Ordnance 6 1/2" speakers sound great as well. I was told by the salesman that these are Crutchfield's house brand car audio speakers. If you are looking for a decent speaker for a good price, I would not hesitate to buy a Sound Ordnance product, especially this sub.

Pros: good bass, good price, built in amp with plenty of power.

Cons: not that compact, but not huge either

Big Sound, Small Price

EricE from Glendale, CA on 9/30/2014

Crutchfield Customer Review (What's this?)

2012 Honda Civic "Premium" sound system didn't sound quite so premium so I'd replaced stock speakers with Kicker 6.5" 2-way (41DSC654) which was a great improvement in sound quality, but still lacking any low-end oomph. The stock shelf mounted sub really didn't add much to speak of so that was the next upgrade. Due to space restrictions I decided to forgo replacing the stock shelf mounted sub in favor of locating the B-8P self powered enclosed sub in the trunk. For the signal I connected the existing sub high level (1-channel) to one channel on the B-8P (not sure if that's the right way to do it or not, can't get a clear answer out of Crutchfield on that). This sub is exactly what I was looking for. Provides the perfect amount of low frequency boost (even at low volumes) and the small enclosure fits nicely in the trunk area without taking up too much room. It's not going to blow the doors off but it definitely adds the low frequencies that I was totally missing before. Product quality is top notch, good solid construction and easy to use controls. The clear window seems strong and should stand up to the rigors of living in the cargo area. I don't have any feelings pro or con about the clear window or the led lighting since I don't spend much time in the trunk while driving. If you're looking for a great low cost and easy to install sub, can't go wrong with this one. Big sound for such a small box that's easy on the wallet. I would highly recommend.

Pros: Big sound, small enclosure, wallet pleasing price, high quality construction, attractive design, easy to use.

Cons: A bit vague on installation instructions (can't believe I'm the first person to try and connect this to an existing 1-channel sub high level input). Their recommendation was to connect to the L & R speakers, but I would lose the dedicated sub volume control on the head unit, so I don't want to go that way. They also suggested splitting the single sub to low level and then use a splitter, but not sure if that's (a) necessary or (b) if it will improve performance. Still confused on that.

Great purchase for the price. Hook this up correctly and hear the bass you have been missing from your interior speakers. Small size makes it take up the footing close to an average paper grocery bag. I definitely got what I paid for and more in this little unit. Clean, clear bass comes from this little box.

Pros: small in size, clear bass.

Cons: none

Connor from Bartlett, TN on 9/9/2014

Crutchfield Customer Review (What's this?)

I installed this in the trunk of my 1995 honda accord, and wow was I impressed. Definitely did not expect a 80w rms sub to perform like that. I was looking for a lower powered sub because my car's alternator is too old for a high powered one, but you would think this thing is high powered. It's not going to rattle the car next to you, but it will make your seat vibrate and the windows shake. My mom could even hear in the house at a low volume when I first put it in. This was my first time installing a sub and the installation process went smoothly. Great buy and would recommend it for anyone on a budget.

Pros: Great value Louder than expected Good sound

Cons: Can't think of any

If you under 25 or maybe even 30 you probably need to look at a different sub-woofer. Although this sub is MORE than capable of making the rear view mirror vibrate and sometimes I'm surprised just how powerful it really is, it will not deliver the destructive force which most younger customers are usually looking for. But if you've had enough birthday's and put a few notches in the maturity belt AND appreciate some serious bass to round out your car tunes for a low price then this is the one for you. I am NO expert is Sub-Woofers. However, I know enough about music and have enough of an ear to appreciate good sound. This sub will fill in those low notes that interior speakers just cannot produce and will do it at a low price without sacrificing a large amount of trunk space either. It's actually a rather nice looking device as well. Is it THE best out there, I doubt it. But for the price and when you've got bills to pay this one does nicely! I highly recommend this sub for those on a tight budget and who simply want to fill in those lower frequencies that can only be produced with a sub-woofer. This Sub turns my 45 - 60 minute commute into a 15 minute "Hey, I home already and I still need to finish my tune" ride. Nice job Sound Ordnance!

Pros: Low Price Built-in Amp Relatively simple to install due to built-in Amp Sufficient power and bass response for most music Good Looks On / off switch for the decorative LED's Sounds fine!

Cons: Won't shatter the glass in the car in the next lane over.

This sub is very easy to install and has a surprising amount of bass. It won't shake the guys car next to you, but it will fill out the lower end of your audio system.

Pros: Cheap, build quality, bass

Cons: N/a

Big bass in a little package!

S2KiLLA from Boutte, LA on 8/23/2014

OMG, i definitely wasn't expecting a 160w sub to hit like this! I've had sound setups in the past, and I didn't like how much of my trunk was left after. So my 27th birthday was approaching and since my latest car was already wired for an amp I figured I'd get something for my birthday. I was leaving towards a bazooka tube, but then I stumbled across this thing for even less money and looks way better. After reading so many great reviews I had to check it out. Hooked it up today, and MAN! You'd never think it was an 8" sub.. Love this setup and the fact that it's an all in one deal..

Pros: Hits great, looks great, awesome price.

Cons: No cons really, but it's heavier than I expected.

Surprisingly strong bass

Ryan from New paltz, NY on 8/14/2014

Crutchfield Customer Review (What's this?)

This sub hits much harder than I ever expected. I wanted something to just round out the overall sound in my car and this sub did an awesome job of just that. At high volumes it does start to drop off, most noticeably with bass heavy music. I bought this after previously running a 600 watt rms 12inch. So I knew it was never going to have bass as deep as I was used too, however I have been thoroughly surprised by how powerful this 8 inch hits in this nicely tuned enclosure.



Massive sound/Built like a tank

CalM from Hartford, CT on 8/8/2014

I went along with this purchase after reading a lot of the reviews. I will admit that I was worried about it filling out my car through the trunk (I drive a Civic LXS 2009) but I was immediately WOWed once I got things up and running and set correctly. I have 4 polk DXi651s speakers and only 4 RCA inputs on my head unit. I plan to use a splitter to run the 4 speakers to the "Front" connection and then keep the SW on the "Rear/SW" RCA ports. So as of right now, I have the front speakers going and this monster in the trunk... I mean seriously, it's an 8 inch sub and 80 watts blah blah blah but this thing will envelope you in warm clean present bass that sounds like an absolute thunderstorm (if you want it to) and compliments the system marvelously. It's loud inside and really not obnoxious outside of the car with the windows down and doors closed. At only 120$, you would be silly to not get this if you're simply looking for something relatively compact with a lot of balls and nice features. Get excited and get one. Also, I haven't Velcro'd it down yet or anything... The carpet exterior hold nicely to the trunk floor and this thing has some weight to it, so don't let the pictures fool you. Measure out the dimensions with a measuring tape or something to get a true idea of what it is.

Pros: The bass slams for it's size and power. Very well built product. Doesn't make my hair shake or rib-cage crack (which I appreciate).

Cons: I didn't get this way back when I replaced my stock door and rear speakers

perfect fit.

Cookie from Rutland, Ma. on 8/1/2014

Crutchfield Customer Review (What's this?)

I purchased this for a 1971 VW Beetle so space was an issue. This unit fits perfectly in the space behind the rear seat and completes the sound system very well. It is connected to an Alpine CDA 9884 and runs with 4 cheapo Pyle 5.25 speakers. Sounds great.

Pros: Good punch. The lights are a nice touch.

Cons: For the price, nothing. An optional remote adjustment would be nice though.

Big Sound Little Package

Paul from Houston, TX on 7/29/2014

Crutchfield Customer Review (What's this?)

After reading so many positive reviews I figured why not give this sub a shot. I wasn't looking for a big boom sound. All I wanted was to round off the low end which this powered sub delivered perfectly. Plenty of power when you want it.

Pros: Compact box that doesn't take up much space. Plenty of power with just 80 watts. THE PRICE!

Cons: None!

Decent sounding little sub

B.S. from Wailuku, HI on 7/21/2014

Crutchfield Customer Review (What's this?)

I was looking for something small and self-powered to augment my system (Sienna van.) When I was in my 20s I used to roll with 2x 12" sealed then later settled down with a 10" bandpass. I'm not looking for SPL anymore, but I wanted something that will round out the rest of the system nicely. Have an upgraded head unit and speakers but was missing some bottom end. Was about to order a Bazooka 8" and I came across this B-8P system. I must say that I was surprised at how compact it is. And it puts out clean sound. It's not going to shake the next car over, and I wouldn't recommend it for someone that's using externally amplified main speakers. But add it to a stock setup or a lower powered setup, it adds good bottom end and reduces distortion in your main speakers since they're not being asked to put out frequencies below 120Hz. Oh and free UPS shipping to Hawaii? Crutchfield rocks!

Pros: Clean sound from a compact unit. Very inexpensive. Free shipping to Hawaii!

Cons: If I have to be picky, the blue power LED is too bright so I put a piece of electrical tape over it. I can also see this being underpowered for a sedan if it's sitting in the trunk. Works well in something open like a wagon, hatchback or van.

Solid Sub Choice

Jeff from Missoula, MT on 7/20/2014

Crutchfield Customer Review (What's this?)

After installing this, I can definitely see the value proposition that people here rave about. I was concerned, like many others, about what a single 8" sub could really do in a reasonably large vehicle like my Nissan Pathfinder. Those concerns are a thing of the past now, I'm super happy with my "bargain basement" powered sub and will keep it for the long term. If you're familiar with the differences between a sealed box and a bandpass box, this will produce typical bandpass bass. It's not quite as "tight" as you'd expect from a sealed box, but that's not a major deal when you're simply seeking filling out the overall sound. This thing certainly provides enough thunder for my needs, I can feel it and it gives me the satisfaction of a reasonably hard hitting system. I still can't believe the price, though...value-wise, I think you could spend a lot more and get a lot worse. When I first lit the thing up, I had to ask this thing on? I was I started looking at how my new deck was set up. Sub output on? Check. Sub gains? Eh maybe needs a little more. Bass gains? Maybe let's give it even a bit more. I think next song up on the radio was a bit of old school AC/ was but a moment before I found myself immersed in the sound, the kick drums hitting me like a sledge hammer. I totally forgot I was tuning the radio and just became lost in the music with me grinning ear to ear over the quality of my sub-$300 system. Good value sub!

Pros: Great value proposition Strong enough for a decent sized vehicle Good size LED can be tuned on/off Enough power to run the sub Integrated LPF & Phase settings Easy to read hookups Quality connections Free shipping

Cons: Bandpass bass - not as tight as sealed boxes Not much else, really

After 2 years, still thumpin'

Batman from Simi Valley, CA on 6/23/2014

Crutchfield Customer Review (What's this?)

It's been 2 years since I bought this sub and I am still amazed at how great it sounds. The built in amp has held up great. The sub has had no issues. I love watching people look around when I pull up behind them and they try to figure out why their car is vibrating. ;-) ;-) ;-)

Pros: Great price. Excellent sound.

Cons: None

it was average

Kate from Omaha, NE on 6/14/2014

Crutchfield Customer Review (What's this?)

This was my first sub so I didn't really know what exactly to look for. When I asked the lady on here she told me this would have enough power for my little car but it really didn't. I was never satisfied. I would turn the power up but it never performed to my liking. Then one day it all of a sudden didn't really work anymore and I couldnt figure it out!! I asked 3 of my friends and no one knew. So I sent it back and have dreams of a real sub one day.

Pros: small, confusing to others

Cons: everything else

Big Sound on a Small Budget

AudioDad from TN on 5/30/2014

Crutchfield Customer Review (What's this?)

The S/O B-8P is an excellent value. Why might you ask? It's an all in one unit priced under $120 that can deliver more than adequate bass to any vehicle. Sturdy enclosure that is stroller proof. If you don't know what stroller proof is, you don't pack and unpack a giant stroller for your kids on a daily basis. As most people can relate, I updated the entire sound system and was missing bass. Since I have a wife and 2 kids, I don't have a huge budget for car audio so I was limited on my choices. Not to worry, Crutchfield had my back with the B-8P. Quick shipping, quick install, quick test, quick tune, quick smile from my wife as if I was the 17 year old with two Rockford Fosgate 15"s she fell in love with. I'm mid 30's but still a kid at heart by the way. Country, Rock, Rap, Kids Bop, it doesn't matter cause it all sounds good with this sub. I'm sure this unit has its limitations, but I will never come close to needing to meet them with my listening habits. Dads typically act rather stupid when they hang out together, so yeah, now we are blasting that old school rap, rock, etc and we really don't care how dorky we look. And yes, the previous reviewers are right about people thinking you have a set of 10's or something similar dropping that bass they are hearing. They are always surprised to see the meager little box setting in the cargo area. You can turn the lights off inside this box which is a great idea, because lights are the one feature I didn't need.

Pros: Value, Value, Value. Bass, Bass, Bass. It doesn't rattle my ride, but fills it with sound.

Cons: No cons here. This thing is perfect for the decerning dad on a budget.

Fills in the lows

buyer6060 from Pinole, CA on 5/27/2014

Crutchfield Customer Review (What's this?)

I needed a powered sub to fill in the lows. Knowing I don't need two 12's to blow out my auto body panels, this fit the bill. Clear, punchy lows without the brain rattle to round out the sound. Now, the four 6.5 speakers can concentrate on anything over 100hz, which is where I have my HPF set. Clarity is more important to me than pure SPL.

Pros: Just what I needed to fill in the lows.

Cons: Took up a little more space than I thought for an 8 inch box. I have the Infinity Basslink in another car which has a smaller footprint.

Cons: Honestly none.

Patrick from State Center, IA on 4/6/2014

Crutchfield Customer Review (What's this?)

First, let's just say I am 100% happy with this. More details on that further down in my review. But let me qualify something first: Up until 10 years ago I did a lot of freelance work building tuned/ported boxes, usually using JL Audio subs and amps, or Kicker. One of my designs set a local record for bass output, using JL Audio 12W0's and a ported box with a firsr-gen JL monoblock amp, and hit 149 db with only two subs that had no business being that loud. That said, I always took pride in the quality of my work, and the quality and clarity of the sound. That being said, I knew this powered sub wouldn't be pavement-cracking in terms of sheer power, but after reading so many positive reviews, I had to give it a shake for under a hundred bucks. Never heard of Sound Ordnance before, but what the heck. So this arrived the other day, and today I installed it in the trunk of my daily driver. I also just installed a new Kenwood head unit and door/panel speakers as well, and was looking forward to some extra lows. The result of this sub install? Worth every penny. For a low-power 8" sub, this thing is efficient. Great lows. Bandpass boxes can be really teicky to tune dimensionally, but this thing is solid, and well-balanced I might add. You can actually feel it, and the sound quality is perfect for any factory or aftermarket setup that is looking for deep bass with excellent clarity, without breaking windows. Build quality is great. Awesome value, period.

Pros: Great sound quality, can actually feel the lows, solid build quality.

Cons: None

Big Boom in a Small Package

Robert from Toms River, NJ on 4/5/2014

Crutchfield Customer Review (What's this?)

I was quite suprised at the amount of bass this tiny subwoofer enclosure produces with a variety of music like rock/metal/techno/dance/rap! I installed the sub in the trunk of a small coupe car and it actually hits pretty hard with the rear folding seats upright (closing off the trunk) and it sounds even better with one or two seats down (exposing the trunk). The small footprint of the enclosure worked out well because my trunk space is valuable for lugging groceries and sports equipment. I like the plexiglass window that covers the subwoofer so I can toss stuff in the trunk without worrying about puncturing the speaker. After reading through hundreds of reviews on this product I decided to take a chance and it was well worth the investment. The subwoofer is shipped double boxed so it arrived safely even with a rough shipping courier like UPS! Two thumbs up!

Pros: Punchy Bass, Bass You Can Feel, Sounds Great, Small Footprint, Inexpensive

Cons: No Wiring Kit Included, Makes Neighbors Angry

SO B8-P Incredible Bass for a 8" Sub at this price

Metal Accord from Souh Florida on 4/3/2014

Crutchfield Customer Review (What's this?)

First let me start off by thanking Cructhfield's awesome customer team and tech team, they are #1. I've had 8" subs in trucks and a few kicker subs in a couple of my past vehicles and I don't think I have installed a Sub with as much ease as this one. I put in my Accord coupe and I still can't believe the amount of bass that this subwoofer is pushing out. It is not 2 12" subs or a 12" sub for that matter, but I am extremely impressed with the quality, look and feel of the subwoofer. If you are like me and are not looking to blow your ears out andjust want a nice decent aamount of bass, look no further.

Pros: Quality build, great bass and price is incredible.

Cons: Wish it had a bass remote.

SO B8-p

Aveo5driver from Dawsonville, GA on 3/29/2014

Installed today and my neighbor asked if I could turn it down because her house was shaking, no bull I was astonished that it was an 8 in. Still couldn't believe my neighbor said her house was shaking she's almost across the street from me!

Pros: Hits decently hard and fits perfect for my Aveo hatchback

Cons: I need to figure out how to get the remote switch working

very, very surprising

Alex from Richmond, Va on 3/27/2014

Crutchfield Customer Review (What's this?)

I just got this product today and installed it immediately. Installation was very straight forward; they even have a video on this sub's page on how to install it. It took me about 3 hours start to finish, but then again, I'm very particular about aesthetics and how wires are routed so it probably took me a bit longer than it should have. As soon as I hooked the battery back up and powered the sub up to 50%, I could tell a HUGE difference. I got this to even out the low ends in my system and it does that better than I could have possibly hoped. I'm running an Alpine UTE-52BT head unit, 2 JBL 6.5" speakers in the doors, and 2 JBL 6x9 speakers in the back. The mid's and highs were already amazing with my speakers, but were definitely missing that lower range response. I read all the reviews on this subwoofer and decided to give it a shot because hey, it's wasn't expensive. The only thing I had to buy on top of that was the amp wiring kit which added a few extra bucks. I honestly cannot believe how powerful this thing is. For only being 80 watts continuous, this thing has a very, very surprising amount of thump to it. It's not completely overwhelming, but honestly, it's probably more than I need. And that's coming from someone who listens to a good amount of electronica and metal. I'll admit, I was a bit skeptical at first because Sound Ordnance has a fairly cheesy military theme (it even came with fake dog tags) but boy was I wrong. I highly recommend this sub.

Pros: powerful cheap sounds great

Cons: kind of big (but from what I read, bandpass boxes usually are) doesn't come with anything for fastening it to a surface very bright blue LED power light

Great Power For Your $

B from Indy on 3/22/2014

bought this as a present to myself for christmas and installed it myself a week later. i have it all tuned and it works perfectly! i needed a small sub to round out some three way speakers in my dodge dakota and this does the trick. i listen to mostly rap and dance. its boomy and loud

Pros: loud, small, cheap, easily installed, quality, visually appealing

Cons: not super tight bass (dont care because I'm going for volume not crispness)

Cons: None

Not a large amount of bass, but pretty good

Matt from Westminster, SC on 3/6/2014

Crutchfield Customer Review (What's this?)

Price vs Bass produced is definitely worth it. Finding an amp and sub for this cheap is impossible. The thump is noticeable but nothing crazy. I have had vehicles with 2 10" bandpass, and 2 12" ported, and this comes no where near that amount of kick. However, it is worth the 100 dollars if you want something small you can toss in your vehicle to add some bass. Hits some pretty decent lows.`

Pros: Adds Thump, cheap price, worth the money

Cons: big for an 8", not nearly as powerful as 2 12" like others say

Awesome boom for the buck!

Tony L from Cincinnati, Oh on 3/3/2014

Crutchfield Customer Review (What's this?)

Wanted something small and affordable for my eclipse to liven up the sound some. I installed this and was blown away, it hits harder than i thought it would. Definitely recommend this to people who have a hatchback, suv or a truck that it will fit in. Way better than i thought it would be. Also if it helps, im running a jvc headunit with subwoofer preouts that has a built in subwoofer controller. I have sony 6 1/2 3 ways all around.

Pros: Sounds awesome for an 8" subwoofer. The bass plays low and clear.

Cons: Probably would not sound as good in a trunk styled car unless you fold the seat down.

better than I expected

Just like everyone else stated, if you want competition window rattling police chasing you sound then this isn't your choice. This little guy definitely puts out more bass than i thought though. I have it in a hatchback so im sure it's louder than in a trunk but i love it. Just what i needed to compliment my kicker highs in the doors. Can't beat the minimal space it takes up too!

Pros: Compact size Low price Crisp sound Good looks

Cons: None

As a dad, I wanted a solid system but not the BOOM you get with larger systems. I tried a Kenwood underseet sub and was very disappointed. So I ordered this one and was AMAZED. Not only is it full, no distortion, and has deep low end I wanted. But I can also bump it up to feel like my younger bass head self. You will not be disappointed.

Pros: Loud, deep, low end, no distortion.

Cons: None

Crutchfield Customer Review (What's this?)

I really couldn't ask for more in a sub. I'm a first time installer and it took me maybe 1 hour to put this in my car. A big chunk of that time was just finding where I could rout the power wire through the firewall. It gives off more than enough bass. It has about 9 levels I believe and 3 is enough for me. I'm an 18 yo guy and I listen to mostly rock and alternative. My friends have connected their phones with hip hop and rap and it still sounds great. If you want bass then this will work. If you want thunder I'm not so sure

I wanted to add a little bass in my d21 kingcab. The two 4x6"s & the two 6.5"s(30rms) I have just don't thump. So at less than a foot cubed and $120 I was sold. Was a bit worried about it being an 8" sub and running only 80w rms. Ended up being perfect for my set up. Hits harder and lower than I expected.

Pros: Compact Package, Hits Hard an Low, Cheap

Cons: No thump thump boom to announce your imminent arrival.

Sound Odrinance BP8

Homer from Jermyn, PA. on 1/8/2014

Crutchfield Customer Review (What's this?)

Overall a great powered sub! Im a firm believer in you get what you pay for. For the price, what more can you ask for. Powerful sound to give your stock system the bass it lacks, the extra bass you were looking to add, but do not want an over powering "bump". This deserves a 5 star all around. Built well, easy to wire, sounds great.

Pros: Easy to wire, amp Is built right in! At 80 watts its not a strain on the electrical system, even after long bass runs, and hard repetitive hits. Very user friendly setting to get the bass sound best for you.

Cons: Well I will start with the led lights, they are a little over the top. No worries there is a switch on the unit to shut them off. Produces great in the box, but personally not a fan of the see through plastic panel, the unit fits almost discrete in the back of my suv, but it seems to scratch rather easy with minor stuff brushing up against it. Those are the only two flaws I noted. The low end of bass hits, drops, and runs are distorted but keep in mind, lower powered 8 in. Sub will do that.

Nice bass boost that doesn't attract unwanted attention

ksang from Reading, PA on 12/30/2013

Crutchfield Customer Review (What's this?)

I chose the B-8P because I wanted to add a low end to my system without sacrificing too much cargo space or attracting attention from potential thieves. I'm happy to report that this was the perfect solution! It adds a modest bass boost to your system, but if you're looking for punchy, car-rattling bass, you may want to consider other options. I should also add that an amp wiring kit must be purchased separately to install this sub. I found a 10 gauge kit, and that worked just fine.

Pros: Easy setup Enhances music without drowning out highs and mids Illumination can be turned on or off Great deal for the price

Cons: No wiring included May leave something to be desired for bass junkies

Very pleased so far

DanielM from Texas Hill Country on 12/16/2013

Crutchfield Customer Review (What's this?)

I'm happy with the sound, although because I installed it in my travel trailer, I really have to keep the level down, like WAY down. This thing could really pump out the bass. I was surprised by the size; I installed under a dinette seat in the storage area, and had to cut out one of the seat supports to drop it into place, then install a modified brace over it that lays in place, just in case the sub had to come out again.

Pros: Really fills the sound out coupled with the tiny factory speakers.

Cons: The instructions weren't all that clear. I fished speaker wire off the Speaker C outputs of the Jensen RV unit, and thought the high level input would trigger the sub, only to find that it still needs to have the 12V trigger, forcing me to take out the head unit and run another wire.

Awesome CX-5 Bose Enhancement

Scott M from Smyrna ,TN on 12/15/2013

Crutchfield Customer Review (What's this?)

I bought this little sub because I wanted something to enhance the bass in the rear of my 2014 CX-5 w/Bose factory system. It has subs in the front doors but I wanted something for the rear that wouldn't be overpowering. There were no clear instructions or kits to make this happen but when this sub went on sale for $99.00, I couldn't resist. After locating the factory Bose amp in the passenger side kick panel area, I located the output wires to the door sub and quick tapped into them for my input to this sub. After a few hours of experimenting with the stereo's fader and the sub's crossover frequency and level adjustment I am very pleased with the results. It adds a nice thump to the rear of the car and along with the factory subs is more than enough bass for my car. I'm a live FOH sound engineer and my musical tastes run from Country to Metal. Progressive Rock stuff like Yes, Dream Theater, Steely Dan etc..sound especially great now with the added low end. With the differing characteristics between the door subs and the Sound Ordinance in the rear there are times where drum fills sound like they are moving from front to rear as well as left and right. I think this sub is a great deal and is a great addition to enhance any factory stereo or system lacking bottom end. At $99 it was a steal but I feel it is well worth the normal price as well.

Pros: Compact size and versatile installation options. It looks and sounds great!!

Cons: None that I have found

It did what Crutchfield said it would do, added bass to my stereo. For the price and ease of installation you will not find a better product, with my windows up it sound like I'm in a concert, very impressive, with the windows down sounds like a normal car stereo.

Pros: ease of installation price

Cons: little bulky for a 8"

Completes the system, great sound, easy to tune

Pros: provides enough punch inside the vehicle, without shaking the car next to you, No one outside the car can tell how hard it hits.

Cons: None, it's bigger than i thought

great sub

Best bang for your buck



Great product, even better when on sale

Carter from Fayetteville, NC on 10/26/2013

Overall a great product. Looks cool, solidly built, and puts out great bass. Just don't expect it to be something it's not. If you want serious big time boom, look somewhere else. But if what you need is a nice thump in the low end of your system, this is it. I got it for under $100, and it's worth every penny.

Pros: Good bass, well built, great (sale) price

Cons: A bit bulky, especially if you have a smaller car

Was looking for a powered sub to put into my sons 1958 Bug. His sound system was pretty lacking in bass. So I bought this for him for his birthday. Easy to put in and set up, and when we powered up the sub, big smiles all round. Definitely worth the money, puts out more than enough bass, really pleased with it.

Pros: Great bass at an affordable price

Cons: None

Quite Impressed!

I had some worries after ordering this, wondering if the bass would be deep enough after reading some of the few negative reviews. I had this installed in my 2009 GTI with OEM headunit today by some Echo Park boyz-in-the-hood (for $40, not even worth trying to do it myself!) and I am impressed. I have somehow lived without a car for the past decade, though was pushing 4-10s in my last car (RIP Acura Legend). Fast forward, in my 30s now, and was looking for something to round out the bottom end in the factory system. After install, put in the new Gucci, and it slammed. Slammed in the sense that I got blurry vision. Granted, the level was "turnt up", but damn. After some adjustments (not wanting blurred vision), this sounds great. My concerns about lack of bass were totally unfounded. The bros at the shop were impressed with the price/sound combo. Also, it takes very little space up in the hatch--can still fit a bike in there with lots of room. Also, you can hear it outside of the car, though not in a wake the neighbors sort of way. What a great purchase, although my wife probably wouldn't agree. I encourage anyone looking for a small unit with impressive sound, but not looking for window shattering, "steal my system" sound to buy this. I listed to rap/garage/punk and it all sounds excellent.



Great Product

Sounds great and easy to install. Using this on my Pontoon Boat to add a little bass.

After reading over 100 reviews on this sub, I decided to get it to put into my 2013 Honda Accord. I have had this in my car for about a month now and I cannot say it hits like a big sound system, as some reviewers have written. I was only looking for something to fill in the missing low end from the factory sound system. I can say this sub does the job. After tweaking the gain and adjusting the setting on the radio, this sub gives me just the right amount of low end base I was looking for. This is by no means a car rattler, but it does still vibrate my mirror when I have turned up with the windows down. All in all, this is a great sub for the money. I would by this again as well as recommend it to anyone looking to enhance a sound system with out rattling the car.

Pros: Small enough to still use my trunk for everyday use. Light weight for easy removal if necessary. Not an overbearing sound.

Cons: No remote base adjuster available.

Great little unit with big sound. Just wanted reasonable price to accent bass in music. If you are the type that wants to rattle your windows, move on. If you want good bass accents, a good price and a good looking unit that doesnt take up a lot of space, this is it.

Pros: Special thanks to phone line help people tha
