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

Written by: Christian from Campbell, CA on January 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!

Written by: JWC from Arizona on December 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.

Excellent 8" subwoofer for a great deal.

Written by: James from Wisconsin on December 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

Written by: Joe R. from New York on October 31, 2015

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!!!!

Written by: Jon W from Michigan on August 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

Written by: Dave B from Chicopee,MA on July 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.

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. I highly recommend this sub if you want a little bump in your sound stage to bring it to life. It hits pretty hard for a self powered sub. No complaints here.

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!

Written by: sotto52 from Arizona on February 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

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

Good deep sound

Written by: SG from Durango, CO on January 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

Written by: Brian from Oklahoma City on January 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

A Real Bargin

Written by: Firefighter from Washington on January 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

Written by: slippysauce from Utah on January 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

Written by: Drennen from United States on January 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

Written by: Benjo from Concord, CA on January 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

sub for outlook

Written by: Nate from southeastern Mass. on January 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!

Awesome, but takes time to install

Written by: Spencer from Georgia on December 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!

Great little bass setup

Written by: Mike from Texas on November 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

Written by: Robert O from Minneapolis MN on November 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!

This subwoofer is actually a Dual SBP8A powered subwoofer which is available through alternative competitive retailers.

Pros: Easy installation. Good sonics.

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

great bass for your buck

Written by: Jason from Hope Michigan on November 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

Sound ordnance B-8P

Written by: Ray from Sadorus, IL on October 26, 2014

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

Written by: EricE from Glendale, CA on September 30, 2014

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

Pleasant surprise

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

The Sub for adults

Written by: rdhqcpro from Charlotte, NC on September 2, 2014

Crutchfield Customer Review (What's this?)

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.

Big bass in a little package!

Written by: S2KiLLA from Boutte, LA on August 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

Written by: Ryan from New paltz, NY on August 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

Written by: CalM from Hartford, CT on August 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

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

Written by: Paul from Houston, TX on July 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

Written by: B.S. from Wailuku, HI on July 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

Written by: Jeff from Missoula, MT on July 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

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

Written by: AudioDad from TN on May 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

Written by: buyer6060 from Pinole, CA on May 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.

Written by: Patrick from State Center, IA on April 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

Written by: Robert from Toms River, NJ on April 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

Written by: Metal Accord from Souh Florida on April 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.

Written by: Alex from Richmond, Va on March 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

Written by: Matt from Westminster, SC on March 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

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

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.

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

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

Written by: Scott M from Smyrna ,TN on December 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

Great product, even better when on sale

Written by: Carter from Fayetteville, NC on October 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!

Written by: Michael P. from Los Angeles, CA on September 14, 2013

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.

Sound Ordnance B-8P

Crutchfield Customer Review (What's this?)

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.

Crutchfield Customer Review (What's this?)

Good buy for the money. If you are looking for something that will rattle the windows in the car, look elsewhere. If you just need a little bass to enhance the sound in your vehicle, this may be a good choice. I placed this in the trunk of a volvo S80. Had to turn the gain up significantly to get decent sound but I knew that going into it as this unit is placed in an enclosed trunk which limits its effectiveness in the cabin of the car. I'm sure this would work better in SUV's or hatch.

Pros: Good for the money and optional speaker level inputs make it easy to install

Cons: not great for trunk mount

I bought this subwoofer a little over a year ago. It has outperformed my expectations. It's not going to rattle your eardrums out but does provide a deep strong bass. My fiancé and I like to go to the drive in movie theatre. This subwoofer makes any action movie sound amazing. It may not thump like two 12's but definitely is amazing for a 8" sub. The 3 year warranty is also a plus.

Cons: none

Sound Ordnance B-8p

Written by: Logan6 from Orangce County, CA on May 15, 2013

Crutchfield Customer Review (What's this?)

I wanted some bass to round out my system in my Acura. Both high end Boston Acoustics 6x9 three way and 6.5 in the front. plus Sony head unit. The current setup sounds nice but I wanted a little bass to add to the system that doesn't take up a lot of space in the trunk. In my 40's and I don't want heavy bass like someone in their 20's. After reading some positive reviews about this Sound Ordnance B-8p, thought I would give it a try. Being an engineer by trade and have installed numerous head units and amp and subs since my teens. I'm quite capable of doing installs. But not having the right tools and time was a factor. I brought it to a professional shop to do the install costing $$. The shop tried numerous adjustments but there was only a marginal improvements to the sound. Spent another two hours making adjustments to the head unit and the sub, but no improvements, playing different types on music. Was disappointed on how lacking there was in bass. I installed a 8" Bazooka powered sub in my 2nd vehicle with almost the same setup and the Bazooka sounded a lot better. Thinking about returning this Sound Ordnance and trying something else.

Pros: Nice looking enclosure.

Cons: Sound, not much bass or enough power for any decent bass.

I purchased this to add a little bass to my system and it sounds really good for what it is. I chose the b-8p because my 93 Mustang coupe has a very small trunk and I wanted something easy to remove at the track. The reviews on this was also a selling point, and they are all accurate. This is well worth the money for what you get. Very nice product. This will not beat your face in or rattle your car to pieces, but it will provide some much needed in car bass. Very pleased with this setup

Pros: Nice little setup for a great price. Easy installation. Surprisingly decent bass for an 8" sub.

Cons: The only downfall is now that my girlfriend heard this in my car now she wants me to get her one.

Well I just put this in yesterday paired with a pioneer pdvd4100,sound ordnance p 52's components in the front and helix speakers in the back. My 09 scion tc came with a stock sub but after changing my hu I didn't really have full control over and I just recently decided to upgrade my cars stereo . I got the speakers then an alpine Mrp-f300 to power them wow big difference. I was still a little unhappy with the low end tho so I started looki g into subwoofers but didnt want to spend to much I came across this and the reviews were great so I said ill give it a shot. Didnt take me long to install since I ran an extra set of rca cables when I installed my amp used a distributor block to run this and my amp. This thing sound much better than I thought I think u get much better performance if your hu has dedicated subwoofer rca outputs. This thing thumps I listen to mostly rock type music and wasn't sure if the box type would hit the kick drum like I wanted we'll it does so I don't need to worry about that any more and I play some rap once in awhile and it hits hard try playing black eyed peas boom boom pow I hate the song but its a good bass to test this bad boy out. So as of 2 days I'm Very happy thAnk you crutchfield

Pros: Good bass .good price ,good look

Cons: None so far

Excellent for Rounding out the Sound

Written by: GCH from Leesburg, VA on April 6, 2013

I've never had a decent car audio system, but a friend turned me on to Crutchfield when the factory HU in my 02 Protege failed. The master sheet and tools made it so easy to replace, I went on to replace the front speakers with a Crutchfield recommendation, then the back ones as well. Still lacking bass, I started looking at subs. I didn't want to spend a lot. I ruled out the MTX small sub because it has no grill and I have to put stuff in my trunk. The cone is stiff enough, but I worried about tearing the surround. The small B-8PT got good reviews, but one reviewer said "not as much punch as the B-8P." Since the footprint is about the same, and since the bandpass SW is a little cheaper, I decided to go with it, knowing if it didn't work for me I could return it. Still tweaking it, but very happy with it. The SW allows you to get more bass with less volume. If you are into rap, or like to play music so your ears are ringing when you get out of the car, this won't do it for you. But classic rock and jazz (e.g. Boston, Kansas, Sade, Steely Dan, Yes, Yellow Jackets, etc.) played at comfortable level, it really fills out the LF and has nice, tight, punchy sound. Adds a lot of clarity to bass lines, bass and lower drums. I'm very happy with it. Thanks, Crutchfield.

Pros: Aesthetically pleasing overall. Carpeted is glued down nicely, and the embroidered (not painted) "Sound Ordnance" symbol looks classy. Fits in the trunk without taking up all the space,. Fills out missing LF for music at moderate levels (I don't turn the volume much above 22 out of 35 max).

Cons: Some screws are driven in a bit crooked, evidence of hasty assembly (which probably helps keep the cost down) - not a big deal since it's hidden from view & you have to look closely to see. The connection slots are a bit narrow for spade clips for 8-10 AWG wire (which is what Crutchfield recommends for this Sub), & I had to use a grinding wheel to narrow them before attaching them to the wire so they would fit the slots - not a big deal if you have grinding wheel, but spades won't fit w/o mod.

Great sub for the money. Those who said they couldn't even tell if it was on must not know how to set it up correctly. This thing will NOT rattle your windows, but for those looking for some low end to round out the sound in their car, it's well worth it.

Pros: Price, Value. Sound

Cons: My only complaint is that the dimensions weren't quite accurate on, and it wouldn't fit under the seat like I was hoping (Van), but it's in the back and it sounds great.

Incredible bass for only 80 watts

Written by: Cadster007 from Morgantown, WV on March 11, 2013

Crutchfield Customer Review (What's this?)

I have been dragging around a large speaker box with two Pyle driver pros from 1989 and a 200 watt amp. This thing has more bass than my old setup. Plus the amp is built in so no need for separate amp. I currently have a 2010 Subaru outback sport and it only takes up a quarter of my hatchback space. Great sub for a small hatch back car with limited space. Don't get me wrong, this is not equivalent to 1000 watt amp sound, but I personally don't like my stomached rattled by bass. It does make my hair move at times, but won't make you sick. :)

Pros: Unbelievable bass sound from only 80 watts at a great price. Very compact. Built in amp, no need for two things taking up space.

Cons: Don't really have any!

Sounds just like my old Rockford Fosgate Punch 8" in a plexiglass box, but for significantly cheaper. It is exactly what I was looking for. Inside the Trailblazer, the bass is solid, clean and booming - but it doesn't carry far. From outside the vehicle you can't really hear it, so it is stealthy. I'm glad I gave this brand a chance, I almost didn't.

Pros: Cheap as hell, great sound, would compare it to Rockford Fosgate. Sorry RF, think I found a new brand. Quiet from outside the vehicle, nobody is going to follow you home to gank it if you keep your windows up.

Cons: none.

I am soooo glad I did. This thing sounds fantastic - my music is so much more alive and I hear things in old songs I never heard before. My musically taste is evolving because of this thing! I'm not a Rap guy, but I do really like is how it sounds with my Pandora "Chill" station...the bass lines from Thievery Corporation are unbelievable. Not only that, but I think my hair may be getting darker too... Unfortunately, the sub had a wiring issue and would pop consistently on power up - confirmed to be defective after a little diagnostic help from Crutchfield. Three days later....a new sub was at my doorstep. Unbelievable! THE ONLY THING BETTER THAN THIS SUB IS CRUTCHFIELD'S CUSTOMER SERVICE...BUY CRUTCHFIELD - BE HAPPY!! Thank you guys!!!

Pros: Heavy bass response, well made porting and cabinet, beautiful acrylic cover the protect speaker as well as lights which illuminate the cabinet wonderfully. Very simple set up with and awesome price tag.

Cons: It has a cabinet so it takes a slightly more space than a flat sub that goes under the seat, but still, very small compared to most cabinets

Great Sounding Sub

Written by: Jason from Florence, KY on December 7, 2012

Crutchfield Customer Review (What's this?)

I purchased this for my daughter after reading all the reviews. I prefer the sound of a bandpass box but was a bit skeptic of just an eight inch sub with an eighty watt amp. Plus I have always been a fan of big bass and preferred 12 inch subs because they were well balanced in responsiveness with a good deep sound. After reading all the reviews I was anxious to try this thing out. I certainly do not hear notes that some people are claiming with it sounding like a 12 but I have to admit I am pleasantly surprised by the sound that comes out of this box. Notes that fall in this subs range are very strong and solid, notes that fall in the very low end barely make any sound at all. So if you listen to a wide variety of music this will be great and exactly what you are looking for, sounds awesome on everything. If you listen to rap or anything real low, this will not fit the bill. I have heard a lot of systems in my time, installed for 4 years with Circuit City and this is a fantastic package especially for the money... I would say it is worth a lot more.

Pros: small complete package, hard to find above average performance, I would say excellent excellent price point

Cons: does not play real low notes at all

Written by: KLo from Raleigh, NC on October 29, 2012

Crutchfield Customer Review (What's this?)

I really like this subwoofer. It was exactly what I was looking for. It's relatively small, self-contained with the amp, and easy to install. The price is really good also. Keep in mind, though, that this sub has only 80 watts and an 8" speaker, so it is not a major thumper. I wanted a small sub for my 2003 Accord that would enhance the bass from my other speakers and give me a little feel of the bass. For what I wanted, it sounds great. This sub is perfect for that. If you're looking to have some serious thumpage, this speaker probably won't give you that.

Pros: Size, ease of use

Cons: None

Powerful 8 inch sub

Crutchfield Customer Review (What's this?)

This sub is a BEAST!! Especially for the size. I've been playing around with the settings now for about a month and come to realize that it sounds best turned up halfway. You can hear/feel plenty of bass without over doing it at that setting. Now I can crank my music with a smile on my face. ;-)

Pros: Not over powering and sounds great for both rock and pop.

Cons: None.

I was gleefully stunned when I finally opened the 3rd box (came triple boxed) quality is top notch. Its also small so it is very easy to place out of the way. bass from this thing is nothing short of suprising for its size and power rating. it doesn't boom down low like a high power 12 in a ported box, but it more than evened out my sound with amped door speakers

Pros: sound, size, quality

Cons: doesnt like to go really high or really low

Nice sound for good price

Bang for the Buck

Just installed in my 2012 Mustang GT and WOW what a difference! My car only came with the basic stereo with 4 speakers, pretty crappy sound i must say. So I changed the stocks out with Fosgate 5X7s and added this Sub and what a difference it made. We actually enjoy listening to music again on road trips. This little Sub sounds A LOT bigger than it looks. It took me about 3 hours to hook up, had a little trouble with the wiring. I highly recommend this product.

Pros: Looks good and sounds even better.

Cons: Needed better instructions for installation in the box.

Great for the money!

Installed fairly easily in an '88 Mustang convertible using the rear speaker leads. The car has the stock "Premium Sound" option and after replacing the ancient Ford junk speakers the sound still needed some "umph" to it. This was just the answer and just fits in the tiny trunk of the convertible. The speaker level ins worked fine and the sub level is at less than half. The result is great for someone who doesn't really care if their system can go to deafening levels. Note: It really sounds great for an 8" with a small built in amp, but be aware that this is mostly because of the box design. And also note that because of the bandpass design the bass is somewhat more muffled and indistinct sounding than you may be used to with say a sealed 10" sub box and bigger amp. It also doesn't get really low or do well with anything over 70Hz either - but it wasn't meant to.

Pros: Great, affordable solution for those wanting some bass to compliment their stock or slightly upgraded system, and an easy install.

Cons: Not serious but it has a slightly limited frequency range because it's an 8", and somewhat "indistinct" sounding bass because of the box design. A design that also helps it get quite loud for what it is. No stars docked.

Whoa!!! Its pretty strong and small. I had a smaller car with two 10s before. Now I have 2010 For Fusion and just this little 8inch and it is as strong maybe even stronger!!! All this is with the factory stereo and speakers!! I gotta upgrade everything else. I was on a low budget witch is why I havent changed stereo yet. I got two kids (3 and 8months) so I gotta turn down the bass levels, but when daddy is going to work it's on like donkey kong!!!

Pros: Strong and small.

Cons: uhhhh, none. Maybe just that I didn't get it sooner!!!

Excellent Buy!

Crutchfield Customer Review (What's this?)

I've owned this product for over a year now. I'm glad I went with this over separate sub, amp, etc. It was easy to setup, the most difficult thing was just trying to find the best way to run my wires to the trunk. I own a little Accent so I am able to get the nice bass in my music without taking up a lot of space. I am still able to use my trunk without too many problems. For me, the output is perfect. I'm not one that cranks the bass where there is all you hear. I like to enjoy my music and have that nice rumbling in the background. Even at a lower setting, it still vibrates the car and seats. Also can't beat the price where everything you need is right there in a nice package. I would suggest this product to anyone.

Pros: Compact, plenty of bass for most needs, and easy setup.

Cons: For me, there is none. For some, it's not your block shaker where you can feel it blocks away and having people wanting to put a bullet through it (like me ;-) ).

Great.......but could be better

Written by: AustinS from Goshen, IN on July 8, 2012

let me start by saying if this is your first sub and you're planning to replace it when you have the money, please get it. Just know that it doesn't kick anything like even some other 8 inches I've heard. I don't know what I'm going to do to make it louder, maybe take off the plexiglass cover. i will try it and then write back Crutchfield. Some earlier reviews brag that it "kicks like two twelves". This may be true for two twelves from a discount store. almost no resonation, but if all you want is to complete your sound system with a more bass, go right ahead because the sound quality is great. Oh yea, and the installation for a first time user is incredibly easy, gives you directions right in the box.

Pros: Easy set up Good Price Looks awsome Great sound quality Fairly compact

Cons: NOT quite as powerful as the other reviews would have you think

Can't beat it

Crutchfield Customer Review (What's this?)

can't beat the price for this powered sub that is just rocking my integra to death. my buddy and I installed this bad boy in an hour. this is the perfect size for a compact car/hatchback. The controls are so easy to use. Couldn't be happier. I was worried that the sub would slide all over the trunk without tie downs or a harness, but it is heavy enough to endure corners without moving an inch. My wife is so jealous, she wants one for her car now too.

Pros: price, sound


Awesome bass!

Received this yesterday. Install took about 3 hours (first time installing). Sounds amazing, so much bass. I only have the bass at halfway and it's too much for me. Buy this, you won't regret it!

Pros: The bass hits hard Cheap but doesn't sound cheap

Cons: None!

Good Price, Great Sound !

I don't think I can add anything that hasn't already been said. This is a great sub for the money. I'm in my late 40's and was only looking to add some good sounding bass without breaking the bank or annoying the crap out of other people and this sub proved to be just what I needed. The best part of buying from Crutchfied is the tech support you get from these guys.

Pros: Great sounding sub for the money.

Cons: NON....

This made my minivan faster

Written by: Manvan from Azle Texas on June 20, 2012

This sub-woofer bangs so good for the price. Simple installation. Makes my minivan fun to drive. I like sub-woofers. If you want to buy this I would recommend a bit larger gauge wires than the manufacturer provided. Thanks Sound Ordinance for the pleasure.

Pros: It makes your car faster, I like it, simple installation, cheap

Cons: no

This is a nice little unit. I put the B-8P in my Taurus, the hardest part was getting through the firewall! I had no problem with installing it. I got rid of the stock system this week... Put Polk Audio db-571's in the front doors, Pioneer TS-D 6802r's in the rear deck and installed an Alpine CDE-136BT for the head unit. That was a huge difference over the stock stuff. But when I brought up the volume on the B-8P.... I couldnt stop grinning. I was listening to Blackberry Smoke at the time.. Next test song was from Miranda Lambert. Next was Tommy James. Next was Godsmack.. Crimson and Clover never sounded so good, and Godsmack was simply frightening!! Buy it! Your wife will forgive you when she feels it! Mine did.


Cons: None at all.

Excellent bang for the buck... within reason

Crutchfield Customer Review (What's this?)

I installed this in my daughter's 99 Saturn SL2. The car has a low dollar Dual CD head unit, stock rear deck speakers and a pair of OK Pioneer 6.5 door speakers. Needless to say, this is nowhere near a high end set up and the "Wow!" factor is not what we were going for. The system was merely missing all semblance of a bottom end. Not being my car, and my daughter being nothing close to an audiophile, I opted to give the SO B-8P a try. First off, let's address the fact that it is an 8" sub. Big booming sound isn't the name of the game. Decent mid lows is. It is in a bandpass box which does help out immensely, however, it also isn't as tight of a sound as one could get out of a sealed enclosure... tradeoffs, tadeoffs. The amp certainly isn't the cleanest, but factor in price and purpose and it's just fine. Once hooked up we gave it a whirl with various genres of music via radio and MP3 player. The difference was stark! This sub added the bottom end that this system desperately needed. Just my opinion here, but if your just looking to add that bass to a lacking stock stereo system or a low power aftermarket set up, this is definitely an option to look out. High power and high end systems would be better served to look elsewhere.

Pros: Cost. Bang for the buck, Typical straight forward amp wiring. easy to manipulate controls.... and the cheesy LED lighting in the window can be turned off

Cons: Not for huge thundering bass. Compared to other setups it's not up to par (but again, factor in purpose and price and it's a winner)

Great Sub

Written by: Charlie from Manteca, Ca on May 27, 2012

Great little sub in my 2003 Mustang. Very powerful for the little 8 inches and hits far harder than the stock 8 inch in my dad's Acura. Friends are surprised by the fact that that little box is doing what it does, and some songs even have enough bass to rattle the mirror and set off alarms. Paired with 4 6x8 pioneer speakers and a pioneer deh-3200ub head unit, this system was affordable and sounds great! Thanks Crutchfield!



Good bang for the buck

Written by: Chris from Durham, NC on May 26, 2012

Wanted to add some bass to my system in my Dakota ext. cab, bit didn't want to sacrifice much space. It fits perfectly behind my seat and takes up very little space. The sound is incredible. I listen to MANY different forms of music and you can tune it your music of choice. Unless you're looking to rattle your neighbor's windows, this sub is great, especially for the price!

Pros: Installation was a breeze. Took me just a couple hours, and that was with me taking my time.

Cons: None that I've seen or heard.
