The Sound Ordnance B-8P powered bandpass sub comes ready to add some dynamic thump to your ride — just wire it up for power and secure it in your trunk or cargo area. This rugged box houses an 8" sub that delivers plenty of firepower, thanks to its polypropylene cone, treated foam surround, and stamped steel basket.

The handsome bandpass enclosure features 5/8" medium-density fiberboard construction for enduring strength, while a clear acrylic window lets you see the woofer in action. Inside the chamber, four LED lights provide visual enhancement to go along with your bass. The durable black carpet cover protects the B-8P and your vehicle from nicks and scrapes. And the Sound Ordnance logo gives you the added assurance of a 3-year warranty to go with your investment.

Who needs a powered subwoofer?

To produce bass, you need a sub, an enclosure, and an amplifier, and it can be little tricky to match them all up. A powered sub eliminates all the hassle, as the manufacturer designs the enclosure to house the sub and amp together. This all-in-one solution is especially useful in smaller vehicles, where there's no room to mount a separate amp, or in any vehicle where you need every bit of cargo space. Powered subs range from small, flat boxes that fit under your seat to larger boxes that go in your trunk.

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

Written By Jon W, Michigan on Sunday, August 02, 2015

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

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!!

Crutchfield Customer Review (What's this?)

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.

Crutchfield Customer Review (What's this?)

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

This thing kicks pretty hard for an 8". Great value. High quality. Made my stock audio in my 00 accord sound great. Turned the hpf setting on my stereo on so that the regular speakers don't play bass. Sounds great after that. Very happy with my purchase

Cons: None

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.

The subwoofer looks great and does add bass to your car but I was expecting a little bit more from it. But it's easy to hook up.

Pros: Looks good, fast shipping, easy set up

Cons: Bass could be a little better

SO sounds great!

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!

Pros: Great value! Great product! Great Price!

Cons: Wish they listed a 12" version lol

Mother of Bass!

Written By sotto52, Arizona on Thursday, February 05, 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

Written By Joe, Scranton, Pa on Thursday, February 05, 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

Written By SG, Durango, CO on Friday, 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, Oklahoma City on Tuesday, 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, Washington on Sunday, 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, Utah on Tuesday, January 06, 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, United States on Tuesday, January 06, 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, Concord, CA on Sunday, January 04, 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

Written By Nate, southeastern Mass. on Friday, January 02, 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 out.....an 8 won't do that.

Good speaker!

Written By Sound ordance B-8P, Hester, louisiana on Wednesday, December 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

Written By Spencer, Georgia on Saturday, 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!

Cons: None

Great little bass setup

Written By Mike, Texas on Monday, 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, Minneapolis MN on Wednesday, 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, Hope Michigan on Thursday, 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
