Our take on the Sound Ordnance B-8PTD

by Buck Pomerantz
Sound Ordnance

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.

Fill your vehicle with bass, not equipment

Want to put some bass to your vehicle without a lot of fuss? Sound Ordnance's B-8PTD powered subwoofer is the latest version of the B-8PT, one of our all-time best-selling compact powered subwoofers. Sound Ordnance built this new version to perform even better than its predecessor, putting a cool-running 125-watt amp and a rugged aluminum 8" sub in an extremely compact, solid ABS plastic enclosure,so you get years of bass satisfaction. This all-in-one unit frees you from having to deal with a separate sub, amp, and enclosure, saves you cargo space, and simplifies your wiring requirements. Whether it's mounted under your car seat or in an out-of-the-way location in the cab of your truck, this little workhorse will surprise you with its impressive bass and its ability to mesh perfectly with the rest of your system.

Sound Ordnance B-8PTD powered sub

This compact sub delivers strong bass without taking up much space.

Big bass from this tough little sub

A 125-watt RMS Class D amplifier powers the sub and lives on a compact circuit board mounted inside the enclosure. The sub's stiff 8" aluminum cone holds its shape even when playing hard, helping to keep the lowest notes clean, and ensuring a long life for the sub. You can adjust the low-pass filter, variable phase control, and bass boost to get the B-8PTD sounding perfect in your vehicle. Preamp- and speaker-level inputs allow convenient connection to just about any system, even a factory stereo.

Sound Ordnance B-8PTD powered subwoofer

The molded ABS enclosure houses a 125-watt amp and a tough little 8" sub.

Good design helps

The B-8PTD's tough outer casing of molded ABS plastic serves as the sub's sealed enclosure and can withstand some pretty extreme internal pressure changes with no reverberating or buzzing. Sound Ordnance conveniently located the neat, clean, easy-to-understand controls on one side, opposite all the connections, so you won't get tangled in wires as you tune your bass. The control knobs and switches aren't recessed, so you can make adjustments by hand, without the need for a tiny screwdriver.

  • powered subwoofer with heavy-duty ABS plastic enclosure
  • 8" woofer with aluminum cone
  • built-in Class D amplifier (125 watts RMS/250 watts peak)

I Used To Be Cool

Written By kzak, Dallas, TX on Thursday, April 17, 2014
 
Here I am, 36 years old, two kids, and thinning hair. The thrilling days of rattling my neighbors windows with mind-blowing bass are long gone. It's time to make sensible decisions in life. But there is still a part of me that wants to crank up the bass when the kids aren't around. The B-8PTD is the perfect solution. It fits perfectly under the seat of my old 4Runner so I retain all that precious cargo space which is now used for hauling junk from the hardware store and strollers. The additional bass is perfect, I was pleasantly surprised by how much sound comes from an 8" speaker. The unit itself feels heavy and high quality. The remote knob is great because you can turn down the bass when you are playing Twinkle Twinkle Little Star on the way to day care, and crank it up on the way back when Beastie Boys - Paul Revere comes on the radio. I shopped around for similar units on another online retailer, and while I found some that were a little cheaper, there seemed to be a lot of negative user reviews. Additionally, Crutchfield included the wiring kit so it was definitely worth the money. Bottom line, if you're looking to give your sound a little extra kick without sacrificing space, then this sub/amp combo is perfect. If you're looking to annoy neighbors and other drivers with loud bass and crappy music choices, then your search must continue.
Pros:
compact size, good sound, good value

Big bass small for factor

Written By Anonymous, Houston, TX on Thursday, April 17, 2014
 
I wasn't expecting this to deliver but I knew I want something to make my factory speakers sound better and that it won't take up space. This sound ordinance packs a punch for its size a lot more bass than I expected.
Pros:
Power for its size. You can hide it under the seat and It doesn't get in the way or take up trunk space. There not need for a separate amp and large enclosure.
Cons:
Don't put it under the drivers seat If you don't mine just a little vibration. I don't mind but for some you might.

Fabulous answer to fill my truck with some bottom end. Rounds out the sound in my 2012 Ram really well. Fits snugly under rear passenger side seat. Solid, tight, not booming, bass response that compliments the sound in my truck nicely. No brainer in my opinion.

Big sound, little space.

Written By Jeffrey Fortuna, Encinitas, CA on Sunday, April 13, 2014
Crutchfield Customer Review (What's this?)
 
This sub is small and feels very well built. In my mind I was going to install this on the side of my MKV GTI's hatch area so the small size was the key reason I choose this over the other powered sub options. Once I went to install I noticed this would fit below the carpet area and next to my full size spare tire. The sub has all the sounds adjustments I could ask for. Once I had it tuned to my stereo and other speakers I'm very happy and getting more bump than I expected. The included corded volume dial has been key since sometimes you want to turn up the bump and show it off and sometimes you like to tone it down and enjoy the ride. I have zero regrets.
Pros:
Small size, built well, good sound.
Cons:
The main power & ground connection terminals are a little smaller than I'd like but I made it work. Mounting options are not very extensive but since I installed this into the trunk foam it was no problem for me.

Great Amp if it meets your needs

Written By Matt, Pittsburgh, PA on Sunday, April 13, 2014
Crutchfield Customer Review (What's this?)
 
This unit was the perfect fit for my needs. In my old age (joke) I don't need a pair of 15"'s and a 1000 watts. I just need a little bump to support the factory head unit. This unit provides exactly, the amp/sub combo in a small form factor is great. I placed mine in the trunk, as the factory system has a small amp in the trunk. It would have fit under my passenger seat without issue (not a power seat).
Pros:
Small and compact Speaker Level and line level inputs Built-in crossover Remote bass boost knob to control bass volume Included Amp Wiring kit with purchase
Cons:
None really

Bought this for my 2014 Jeep Wrangler Unlimited. If you are looking to upgrading bass on the non-Apline stock head unit, this is it! Simple hook up straight out of the box. I installed under drivers seat. Lots of bass and solid punch. I also added 4 recommended Kicker speakers for front and rear sound bar. Highly recommend this powered sub!
Pros:
Easy to install with free wiring kit. Lots of bass and solid punch. Simple adjustments.
Cons:
None

Works great

Crutchfield Customer Review (What's this?)
 
Great price and great sound! I installed in my Jeep Wrangler along with new speakers and head unit. I found the level of bass was prefect for my setup. I installed it myself without any trouble and was happy with sound it produced.
Pros:
Price this is a great low cost add to any system. The bass produced fills out the music in my Jeep.
Cons:
I wish it had feet to mount on a vertical surface.

Great Addition

Written By Cdish, Dallas, TX on Tuesday, April 08, 2014
Crutchfield Customer Review (What's this?)
 
I bought this for my daughters 06 Jeep Liberty. I have put it under the rear, drivers side seat, which does fit. The only issue is that the seat now wont lay flat. (which wasnt a big deal for us) We just felt it was better than being exposed in the back. The unit was very easy to install. Setup was easy as well, of course the biggest part of the setup which is ultimately going to get you the best sound is at the head unit. Bottom line, its a great plug and play sub. It will enhance the overall bass response and give you a much fuller sound. I would say that you should have realistic expectations, as it is not going to blow the doors off, but again, does provide some significant improvement.
Pros:
Easy to install, very compact, super easy setup. the included harness was an added bonus for sure.
Cons:
Not quite as full of sound as you could get in a sub with enclosure, but thats the price you pay for the compact size.

Very nice

Written By MikeH, Harrisburg,Mo on Tuesday, April 08, 2014
Crutchfield Customer Review (What's this?)
 
I typically don't write reviews this close to when I purchase and install an item, so I will only address my first impressions of this powered sub. I mounted it in a 99 Hardtop Corvette on the trunk divider I have installed behind my seat. I first tried to mount it directly behind my seat but I found I didn't have enough leg room. I'm 6'. I chose not to mount it behind the pass seat because I didn't want it bothering passengers. The hook up is fairly simple. Power wire through fire wall, grounding cable to the seat bolt. Run the RCA's to the head unit, run the control switch back to the dash area. I don't have anything to really compare it to as I have never had a boomy sub, except the system I installed in my son's car, but I didn't really listen to that all that much. I find this powered sub does exactly what I wanted it to do. It fills in the lower bass notes nicely that I was missing from my system. As others have said, it doesn't shake the neighbors windows, but it does add those lower bass notes that are typically lacking in a non sub system. In a car as small as a vette this is more than adequate. It doesn't give you that chest pumping feel of a 15" sub, but it does complete my system nicely. I don't suggest trying to install it in a trunk, I feel it's best mounted and used in conjunction with your cabin speakers. My system. CDE 126BT-Alpine KTP 445 power pack-JBL 660C front components-Infinity Ref series 5.25 rear speakers.
Pros:
Ease of installation
Cons:
It's only an 8" sub so don't expect it to be a 12" Not really a con, I just want to make sure you don't expect something it's not capable of.

Booming

Written By mdlbldrnt, Sioux Falls Sd on Sunday, April 06, 2014
Crutchfield Customer Review (What's this?)
 
I installed this unit in an older station wagon. This unit is just the right size for this type of car in my opinion. Great enhanced bass to go with the new speakers I installed. Original speakers were shot. It is compact so I still have cargo room which was my main concern. The controls are easy to use, the hookups are simple and the sound is booming. I love having a remote bass control for the unit on the dash. That is a handy feature. I am still using the original head unit and it didn't have enough power to turn this unit on so I had to add the remote wire to a keyed12V connection. Works perfectly for my use.
Pros:
compact, powerful, good controls, simple installation, bass control on the dash
Cons:
Positive, Negative wire screw terminals are too small. Was difficult to get the 10ga wire to push in cleanly. It worked, but would have liked larger connection terminals since the larger gauge wire is needed.

Good Product for the price

Written By KelllyM, Jonesboro, GA on Sunday, April 06, 2014
Crutchfield Customer Review (What's this?)
 
Purchased to go under the seat in my 97 F 150. I read a bunch of reviews before buying this powered sub, and when it arrived and I saw just how small it really was, I was a little concerned that it wouldn't sound good. After installing the sub (and new head unit, ,four speakers, and 45w speaker amp) I was surprised at how well the sub sounded. This is not a neighborhood shaking bass but blends very well with the new stereo. I listen to mostly ROCK and so far (2 Weeks) I must say this is a great product for the price .
Pros:
Easy to install, fits in tight location, good sound
Cons:
None as of this review

Perfect for filling in bass + a little extra

Written By D, La Verne, CA on Wednesday, April 02, 2014
Crutchfield Customer Review (What's this?)
 
I've installed this about 2 weeks ago, and it's done everything I wanted it to do and more. It fills in my bass perfectly when my mids and tweeters are up, and rumbles when my mids and tweeters are low. It's not going to wobble your trunk, but it's punchy and boomy the right amount for what I'm looking for. I recommend under the seat for the best sound.
Pros:
Great sound, stronger than it would seem like could come from the box.
Cons:
If you're looking for a window-rattler, you need something bigger.

adds nice bass

Written By David G, Odebolt IA on Monday, March 31, 2014
Crutchfield Customer Review (What's this?)
 
I personally love it. It's small but still a tad bit large for 04 Ram 1500 quad cab some modification under left rear seat was needed to fold the seat down properly. But there is not a lot of space in this truck for a woofer if you want to keep the rear seating. The unit works flawlessly giving deep rich tones, perfect for an old man and classic rock and roll.
Pros:
good rich bass in a compact unit very easy to install with supplied wire harness.
Cons:
Power supply post on unit a little small for 10 gauge wire. A very minor,very short lived problem. A couple ears on the case with screw holes would be handy for mounting don't care for the tape so I used small bungee cords, again very minor. Had to modify the compartment lid under the rear passenger seat of my 04 RAM 1500 quad-cab to have room for the seat to fold down properly. Cut the hinges removed top two folds and re-install the bottom piece to mount the unit onto.

Makes the MINI Cooper boom.

Written By Ron, Cary, NC on Wednesday, March 26, 2014
Crutchfield Customer Review (What's this?)
 
This subwoofer works perfect in my 2005 MINI Cooper S Convertible. It is not going to make the cars next to you rattle, but it adds just the right amount of bass to the music and adds a nice kick to the MINI. If you are looking to shake your neighborhood, this is not the subwoofer for you, but if you are looking for a nice added punch of bass to the music and to take the pressure off of your full-range speakers, this is your subwoofer. It also does not take up the entire trunk, and it fits nicely in the cargo area of the MINI.
Pros:
Great sound, easy to install, and easy to configure. Also a great space-saver.
Cons:
No cons for me, but for some, it may not be the intense head rattling thump that they are looking for.

Sound Ordinance Pretty good

Written By Mike in Spokane, Spokane ,WA on Tuesday, March 25, 2014
Crutchfield Customer Review (What's this?)
 
The sub, for an 8" powered unit is pretty good. It is very punchy, with less lows (based off of little experience, I suppose this adequately describes my point). As I had no sub, this is a great addition to my '06 tundra which has 0 space available to hide a sub unless one is willing to spend 700+ dollars. The last set up I owned was 2 10" JL Audio subs in a box within an extended cab Tacoma ... Granted this sounded much better! I understand this is only an 8 and for what it is and the fact that I was able to hide under my passenger seat I give it 4 stars. Boomier lows would have scored it 5 stars.
Pros:
Small and tints under passenger seat
Cons:
To punchy, not boomy enough for my taste.

Fits very well under front passenger 2000 Durango seat.

Written By Nick, Ohio on Monday, March 24, 2014
Crutchfield Customer Review (What's this?)
 
If I could offer 4.5 stars, that's what I'd make it. Since I can't, I'll vote up to a 5-star.

Installation was simple and to the point. I have installed a sub in 13 years, but the elements are all the same. I was surprised to find this tucked nicely underneath the front passenger seat. My next rider will be in for a shock.

I did initially have some trouble with the sub refusing to produce any sound. The LED was on and the high level wires were receiving signal, but no matter what I did (removed wires, power cycled the sub, etc) no sound would emit from the sub. Finally, literally seconds from giving up, I (again) disconnected the high levels and reconnected and BAM, output. I honestly don't know what the issue was (sub was set to Remote Line to turn it on and was jumped from the +12v lead during initial testing), but I haven't had a problem since. I would tend to blame a loose wire on my part before I blame the sub, unless you read other reviews of a similar issue.

As a product of the 90's, I'm revisiting that decade's alt rock and hip hop. Frankly, some songs hit very well with this sub, and some sound muddy. The ones that hit cleanly sound GREAT, the muddy songs could be from the MP3 the stereo is playing or just poor bass in the song.

In general, though, it was well worth the cost and install. It rounds out the highs and mids from the OEM gear nicely.
Pros:
Initially, I was unimpressed with the sub's output and the songs sounded lackluster. Frankly, I was disappointed. However, after further adjusting the controls, it hits much more cleanly and sounds more punchy. Much more impressed and happy now. Certain songs sound great, others not so much. On the songs that it sounds good, it sounds GREAT with and it's a pleasure to have in the truck.
Cons:
It's not a 10" or 12"? That'd be nice, but I was after something I could tuck away and forget about. Aside from the initial no-sound-output issue which inexplicably resolved itself, I have no cons.

Great little sub/amp

Written By sdsuman96, Pasadena, CA on Monday, March 17, 2014
Crutchfield Customer Review (What's this?)
 
This sub/amp is compact, I have a 2012 Scion Iq and needless to say space is a premium. I was easily able to connect the sub/amp to my AVH-7500bt with the supplied amp kit (10 gage). Still need to tweak it a little but the bass is very defined and noticeable. Like most reviewers stated it's not going to shatter any Windows but you can feel it. I have it right under my drivers seat and I definitely enjoy the addition it adds to my small system. I didn't hook up the wired remote but did plug it in to test it out and it works great. Overall very satisfied with the sub and the fact that it comes with a standard 3 year warranty is icing on the cake. I would highly recommend it if you are like me and have limited space to work with.
Pros:
Awesome bass and ease of set up. Great warranty, though Ihope never to have to use it tthough it's peace of mind that it's there.
Cons:
None that I can think of.

I installed this in a 2007 Ford Explorer Sport. It fit under the drivers seat perfectly and with the free EFX 10-gauge Amplifier Wiring Kit, it was a breeze to install.
Pros:
We love the base it puts out. The radio system sounds 100 percent better with the Sound Ordnance B-8PTD subwoofer.
Cons:
The velgro that came with the subwoofer wouldn't stick to the carpet. Luckily, I was able to shorten the wires and the seat adjustable arm keeps it secure.

Tucson Trike

I bought this Sound Ordnance to complete a sound system on my Styre Trike. I built a rack for it to fit on the floor pan of the trike, firing upwards into the body of the trike. Since the bass is non directional, this works very well to enable me to not only hear the bass but to "feel" it as well. Really a cool speaker and the sound is perfect.
Pros:
The adjustments on the speaker enabled me to dial in the sound I wanted.
Cons:
The bass sound is not overpowering (probably due to the "openess" of the speaker location) but the punch is the perfect sound I was after to complete the driving experience. So I'm not sure this is a "Con".

Disappointing product

Written By Beater, Oregon on Sunday, March 16, 2014
Crutchfield Customer Review (What's this?)
 
I purchased this to install into a regular cab 86' S10.

I was excited to install this after receiving it. The finish and feel was excellent as was the packaging. But the bass it produces was not really clean or accurate or powerful. It did give a rather weak "thump" I didn't think it was worth keeping. Keep in mind I wasn't expecting it to pound like a JL w6, but i wanted it to fill out the cab with some nice solid low end. I would not recommend this unit to anyone!!
Pros:
Finish, looks nice.
Cons:
Not powerful enough. Not very clean or accurate.

superb sub

Written By BTH, Massachusetts on Saturday, March 15, 2014
Crutchfield Customer Review (What's this?)
 
This is a great sub for a small car. It fit perfect under the seat of my Saabaru 9-2x. Delivers tight and deep bass;exactly what one would expect from an 8". Solidly built and easy to install. I would recommend this sub to anyone looking to add clean, invisible bass to a smaller car or truck.
Pros:
compact easy to install out of sight tight and deep bass well constructed
Cons:
terminals are a bit small for 10 gauge wire

Nice upgrade for my 2013 Altima

Written By VinnyA, Barnegat, NJ on Friday, March 14, 2014
Crutchfield Customer Review (What's this?)
 
I'm 32 and I've had a few big systems in the past. I recently traded in my 2012 C300 for the 2013 Nissan Altima. Car downsizing for family upsizing. The c300 had the Harman Kardon system with 12 speakers and the Altima has the 6 speaker non-bose system. Needless to say, I was completely taken aback. The stock system is terrible. I'm in the process of upgrading the whole system. First step in the process was something to round out the low end and this sub really did the trick. I'm not looking to set off alarms anymore. Just well rounded, clear sound. I also bought a pair of Rock Fosgate 6.5 components and Alpine 6X9's to run with an Alpine 4X50 RMS amp. The sub was an instant and needed improvement. Nice low end. I had it installed under the passenger seat and the gain control is right in the dash. Great when the wife's in the car. Look forward to installing the rest of the system and giving this sub a chance to break in.
Pros:
Great low end for the price. The gain/volume control is an excellent addition.
Cons:
None yet

Great sub in a Wrangler TJ

Written By Michael M, Schenectady, NY on Thursday, March 13, 2014
Crutchfield Customer Review (What's this?)
 
I bought this to replace a larger sub and amp that were taking up all my truck space in my Wrangler TJ. This easily tucks under the back seat and gives enough bass to fill in the sound. You can't push it too hard or it will distort, but once the levels are dialed in it fills in the lower frequencies nicely without any problems. If you have a Jeep and want a full sound without needing to shake the neighborhood, this is a nice space saving option.
Pros:
Compact

Product good; Instructions bad

Written By Thespis, Texas on Monday, March 10, 2014
Crutchfield Customer Review (What's this?)
 
I waited about a month before reviewing so that the sub was broken in. It fits perfectly under the middle back seat of my 2013 F150. I used the speaker level inputs. The sound is good, but required a significant amount of time spent tweaking of the various controls. If you're adding this to a stock head unit, be aware that the output of your HU may not be enough to turn on the sub via the "Auto" setting. Mine was not, and I ended up having to run a remote wire.
Pros:
Compact size Good sound Great price
Cons:
Auto turn on is not very sensitive. Lots of fiddling to produce good sound

I received the shipment and scheduled the installation utilizing the install card. Everything was perfect and the sub sounds great. It was too large to fit under the seat of my 07 trailblazer SS and was installed in the rear panel. Great sound and produced a great sound without overpowering bass. If you want an upgrade without wrecking your budget and eliminating your trunk space, this is the product for you. It worked perfect with my factory head unit.
Pros:
Easy install, compact, great price
Cons:
None.

I followed the reviews....

Written By Tachyon2601, Seattle on Friday, March 07, 2014
Crutchfield Customer Review (What's this?)
 
...and I'm happy to report that they are spot on! This sub fills my Colorado Extended cab perfectly. It hits clean and takes up very little space. I wanted to mount this underneath my front seat but there isn't much room there even for this sub. I decided to mount the sub in the center of my extended cab right behind the front seat. Looks good and sounds great! Like the other reviews said: You won't rattle any windows but you will certainly crack a smile whenever you turn up your system! Can't beat the value on this one! Buy!
Pros:
Super small, low price, easy install, comes with free wiring kit
Cons:
Nothing to report so far...

Nice upgrade!

Written By Bill, NJ Shore on Thursday, March 06, 2014
Crutchfield Customer Review (What's this?)
 
I did some research and based on price, size (to fit under truck back seat) and other buyers reviews and purchased this unit. I am running a stock head unit and did upgrade the door speakers through Crutchfield not long ago. The issue I had prior to installing this sub is that the speakers would get distorted if I turned up bass and volume. Now I can turn the bass down on the door speakers and then the sub fills in the difference....works out well. I did the install myself and I'm a novice at best...I did use what is called a "Fuse Tap" to run the power on/off from amp to fuse box, this is something I found out about through trial and error. It seems to be a good way thus far, got one at auto parts store. It probably took me about 3 hours or so to do the install, but if I did it again I could probably do it much faster.
Pros:
Price, size, sound. Remote bass control knob is nice to have.

The wow factor

Written By LD, 38671 on Sunday, March 02, 2014
Crutchfield Customer Review (What's this?)
 
I am definately a novice at car audio installation so it took me five hrs to install this sub, but I wanted to do it right and with the help of Crutchfield's excellent technical assistance and their install videos, I pulled it off. When I finally powered the sub up, for some reason it didn't sound that great, but of course I was tired after the lengthy installation, anyway the next day I really took some time to get all the settings on my head unit and the sub just right and all I can say is WOW! This thing really rocks, but you really have to spend the time to dial everything in correctly, its way more than just simply setting everything to the highest level. My JVC head unit allows from 0 - 8, on gain and I have mine set at 6, the sub itself has a remote volume and I only have mine set at the halfway mark. There are many more settings that you will have to play around with to get everything right for your vehicle. Mine is installed under the rear seat of my 2012 Suzuki equator pick up. I also got rid of my factory speakers and went with Crutchfield's recommendations, Rockford Fosgate 65 watt components in the front and Sound Ordnance 50 watt in the rear and the difference between the system I have now and the factory system is like night and day. Oh and there really seems to be a break in period for the speakers and the sub because mine have been in for a couple of weeks and sound much richer now as compared to newly installed. Thanks Crutchfield for a great sounding system!
Pros:
Great sound, all in one system with amp, sub, and enclosure.
Cons:
Can't think of any cons, except maybe a little tough to install, but I'm no pro at installs anyway.

Little sub

Written By poppagroove, Lynn Haven Fl on Wednesday, February 26, 2014
Crutchfield Customer Review (What's this?)
 
This sub was recommended by the folks at Crutchfield to go in my Chevy HHR and I guess if all you want is just a little bass or bottom end that sounds like the factory subs that come in some of the nicer cars today then I can say it does a pretty fair job....but if want a sub that has some "umph"to it THIS AIN"T IT!!!! But to be fair, it does what it was designed to do...it gives you a small, slim sub that can fit most anywhere and adds a little bass to your system...just don't expect it to knock your socks off by any stretch...very HO-HUM
Pros:
Fits most anywhere,small and slim
Cons:
As far as subs go this sub is very weak sounding

Great for everything except electronic music

Written By Anthony B, Haverhill, MA on Tuesday, February 18, 2014
Crutchfield Customer Review (What's this?)
 
I like everything about this sub except for it's response range. I thought I could get over it but I'm about to just send it back. I listen to a lot of dubstep and electronic music and it just doesn't go low enough. I can hear it start to attenuate once the music hits the low lows and the sound comes back at the higher lows.

Overall It sounds great, puts out a lot of sound and doesn't distort unless you are being stupid with it. I would definitely recommend this product to a friend with the warning that if you listen to lots of dubstep, move along.
Pros:
Compact Easy to install Fits perfectly under front seat Good Sound
Cons:
Frequency Response Range is less than ideal for electronic music, especially dubstep.

Perfect for 2004 Tacoma!

Written By Davizzle, Orange County, CA on Tuesday, February 11, 2014
Crutchfield Customer Review (What's this?)
 
My Double Cab 04 Tacoma has very limited space amd I did not want to sacrifice seating area. I'm a research'aholic and spent a few weeks researching and decided on this combo. I am very satisfied. I'm writing this review to also highlight a few things I learned along the way.

This is my first sub so I spent a good deal of reading install reviews & watching videos. I should also note I'm a perfectionist. The install took me 5 hours. I ran into a few snags & time spent testing different locations of placement for optimal sound.

If you have an aftermarket HU, you need to install the REM wire. If you received the free install kit, install the skinny turquoise wire from REM to your HU. I have a Kenwood deck and needed to splice into the blue with a white line wire.

Placement - I had every intention per other reviews to install under the driver seat. It sounded good. I then placed it sideways behind the driver side back seat. Wow. Sounded 2x better. Much deeper bass and the sound filled out the cabin much better.

Just to save others time with the same truck, the back seats are pretty much sealed to the ground/carpet. I had the intentions of running the wires under the carpet, or under the seats, but there is no getting underneath.

I took my time, did my research, watched install videos and had no problems other than a very lengthy install due to my sealed back seats. This is a great investment for the money. It was either this or a pricey custom box, no thanks!
Pros:
Good bass, good size, good price
Cons:
Wish they included recommended settings, but every system and user is different

Sound Ordnance B-8PTD -Impressed

Written By Rey, New Jersey on Monday, February 10, 2014
Crutchfield Customer Review (What's this?)
 
I am beyond satisfied with the sound, size and bass response! I'm giving this product 4 stars simply because I don't know if it will give me any issues in the near future. At this point it's PERFECT and a 5 star winner. I should have bought this last year when I purchased replacement speakers via Crutchfield for the stocks.

If you would like a 'fuller' sound with a tight punch in your Jeep Wrangler, THIS IS the unit. If you're looking to compete with the jerky at the traffic light or to annoy your neighbors, this is probably NOT for you. I must add that this thing is also a space saver.

Thumbs up to Crutchfield as well for their quality support and including the wiring kit with this purchase.
Pros:
size. sound. ease of use.
Cons:
Zero cons.

Size Matters

Written By David, Carlsbad, CA on Friday, February 07, 2014
Crutchfield Customer Review (What's this?)
 
This is the perfect size for compact spaces where large subs or sub boxes won't work. Fits compactly under the drivers seat and provides more than enough bass in my Mercedes 380 SL. As others have said, this won't rattle the windows of your neighbors house, but if you are more interested in the music rather than your appearance, this is perfect.
Pros:
Compact size, adjustable, ease of installation, price, fast shipping.
Cons:
Secures with hook and loop tape. Hope that works over the long run.

Works great!

Written By Mr Jim, Washington on Friday, February 07, 2014
Crutchfield Customer Review (What's this?)
 
For the price, this little amplified subwoofer does a great job. The are some negative reviews on this due to the frequency control only going down to 50 Hz... well guess what, that isn't the lowest bass note the speaker will hit. That is only the crossover setting. Controls are fairly easy. Just set the level (volume) to max, or close to it, set the crossover to max, and then make the adjustments with your receiver. Sound quality is very good, get it set right.Installation is perfectly straightforward, despite the vague instructions in the manual. No, Crutchfield does not provide instructions on this one. Bottom line, if you are looking to greatly improve your antiquated stock system and make the music more dynamic and full,this is a great device for a low cost.
Pros:
Price, sound quality
Cons:
Terminals for power and ground wires are a little small to accommodate the 10 gauge wire. Connectors were not included in the subwoofer box or in the install kit.

perfect for my application

Written By RP, Littleton, Colorado on Friday, January 31, 2014
Crutchfield Customer Review (What's this?)
 
I installed this B-8PTD in a 2006 Ford F150 super crew. I am no car audio expert (electronics scare me), but I managed to pull off the installation without a hitch. I've kept the original stock head unit because it does the trick for me and I really don't care for the look of "add on" aftermarkets, not to mention I don't need all the fancy extras (disco lights, etc.). My stock head unit doesn't come with RCA outputs, but that wasn't a problem. This sub can still be installed WITHOUT cutting or splicing the factory truck wires. You CAN add RCA outputs to your 2006 F150 factory radio without cutting or splicing, just search the web. I upgraded my speakers a few years ago thanks to Crutchfield, but I wanted to fill the bass in just a bit more. This product was the key. I'm not a hip hop or rap guy, so this was perfect for my type of music. I used the free wiring kit supplied by Crutchfield for the install and it worked flawlessly. Thanks again, Crutchfield.
Pros:
Reasonably priced upgrade for a factory system. Plenty of bass for my needs. Relatively straight forward and easy install (I mean if I can do it.....). Excellent customer service and fast, free shipping.

B-8PD is great

Written By am2airframe, Shoreline, CT on Monday, January 27, 2014
Crutchfield Customer Review (What's this?)
 
Before unboxing I was impressed by the military style of the packaging. After opening and getting this sub ready for install, I was worried I may have gone too small, however I soon would be proven wrong. I installed this in my 98 Chevy K 100 XCab with a new JVC head unit, MTX 6.5's, and Kicker 4x6's. This was a quick and easy install and the finished product was an acoustically sound system. I have had many systems in my cars and used to compete in Sound Quality/SPL competitions, but that was back when I was a 16 year old. I just wanted a good sounding system that wouldn't kill my wallet and this was it. The sub is very compact and after dialing in the head unit and the amp I found this sub gave a great punch and decent bass. The bass does not hit at all levels, but I tried it with all different genres of music and I was very happy with its performance. I ran the sub external volume knob after reading another review and it definitely a wise idea. The tech I built my stereo package with was able to get me up and running for 450$$, which was just what I wanted to spend. Thanks again Crutchfield.
Pros:
Inexpensive, compact, sounds great, easy to install
Cons:
A few screw mounts would have been nice

Shocking bass from such a small package!

Written By Lee, NE Connecticut on Sunday, January 26, 2014
 
Ok first off, I am stunned at just how much bass this does in fact put out! I was hoping to add some good bass to my Jeep Wrangler because the factory 4x6" and 4" speakers don't exactly scream power (and that is WITH Polk Audio speakers installed! However, I am not only pleased, but stunned at how good this really is! It's far better than expected and worth every penny!
Pros:
Great sound and price, you just can beat it for the price! Really made a massive improvement in sound.
Cons:
The lack of mounting holes. On my Jeep, I had to build a heavy gauge plate and hang it from my drivers seat. The floor is not flat, and this allowed me to also keep it high and dry. The lack of mounting provisions required me to heavily engineer a system to retain the sub by clamping that little 1/2 flange on each end. In the end, it was well worth the effort, but having designed it to me mounted, would of made the build easier (although, not as nice looking as it turned out!)

Big Sound little Space

Written By F 150 XLT 4door, wynnewood PA on Sunday, January 26, 2014
Crutchfield Customer Review (What's this?)
 
A warning before the good news: 1. Salesman claim you do not need the REM wire, that it will turn on with engine on & turn off automatically if no radio signal is sent. Not true, it will not work - the REM wire must be used. 2. If you Do Not have a stock radio with separate subwoofer RCA jacks or you Did Not buy a new radio with separate Subwoofer RCA jacks the Subwoofer will not work the way it's designed to work. a. You need to Splice into wire harness the Rear Left (+) & (-) wires & the Rear Right (+) & (-) wires. b. Once all that arduous painful effort is complete the only way to control the bass is with your radio's bass control. To turn-up the bass you can ONLY turn up all the speakers at the same time. No separation, nothing but muddy bass - horrible!!! c. the included independent volume control the Sub comes can not be used in this hook-up, it will have no effect - S/O installed in 2001 F-150 XLT 4 door under back seat. 1. (4) new 225 watt Kicker speakers in the doors 2. Alpine HD149BT Radio (RCA jacks yes) REVIEW: subwoofer with this system fills the space so well it merges with the song & you can't tell where the sub is. It completes your sound system & can be cranked up cleanly - no car needs more (some just want more)
Pros:
1. Big Sound that fills the car fits in a very small space, 2. Price is easy on the pocket, 3. self contained Amplifier (nothing else to buy), 4. fine tuning adjustments included on the Subwoofer, 5. housing is metal -very strong/durable, 6. separate volume control allows for adjustments without having to get into your radio's menu to adjust subwoofer, 7. can get loud enough to impress & turn heads, 8. and it can damage your ears (wait that's not a pro is it?)
Cons:
Need to run a power wire (supplied) from battery through the firewall under door/floor/carpet molding to back of vehicle (recommended location). *installation note: emergency brake - a foot break (not hand pull) the cable will exit the firewall via a rubber grommet near gas pedal, Pwr wire can follow same Route. - You want to blow eardrums out, make car/truck rattle, get stupid stares from motorist at traffic lights, tick-off neighbors and attract the attention of local Police get a bigger Sub

More power than you'd think

Written By Steve M, Northern CA on Saturday, January 25, 2014
Crutchfield Customer Review (What's this?)
 
I added this little 8" sub into the factory stereo in a Dodge Ram club cab by simply connecting to the existing speaker wires. I was expecting "some" additional bump but what I got was A LOT of bass. So much so that I have it set way low just so it doesn't completely over-power the rest of the system. At first it sounded muddy but after adjusting the settings it tightened up considerably. I'm sure it would sound worlds better too on a dedicated sub out and on an aftermarket deck. Note: I'm not a stereo system guru so my impression of good bass might not be the same to someone wanting huge sound.
Pros:
Tons of bass and easy to install for the amount of money it cost. It came with the amplifier wiring kit for free and the tech line is nice. Great investment for someone looking for more bass out of what they already have.
Cons:
When the sub arrived the "auto start" didn't function so Crutchfield sent another. But I found I wanted to use the "remote on" plug anyways just to assure that the sub doesn't stay on when the key is off and drain the battery.

Not the greatest

Written By JC, Worcester MA on Friday, January 24, 2014
Crutchfield Customer Review (What's this?)
 
Purchased this for my wife's minivan and used the free wiring kit to install the system. I'm not new to amplifier installation so I know I hooked it up correctly. I checked and checked and tried to adjust phasing and everything else with no avail. The bass from this powered subwoofer is of poor quality. The problem is there are too many overtones and the plastic housing and aluminum woofer resonate with an unpleasant sound that ruins the bass sound. Couple this with the fact that this subwoofer doesn't go very low in the frequency range at all. I installed Pioneer 5*8 speakers powered off the factory radio and this subwoofer doesn't hit any lower than those speakers do. All it does is add volume to the bass that these pioneers are capable of but with unpleasant resonance and overtones. I'm picky when it comes to sound quality but when my wife came to me and said she didn't like the sound either that is when I exchanged it for a much better JL Audio CS110-WXv2 subwoofer instead. This of course costs a lot more but you know the old saying you get what you pay for. Good thing Crutchfield has great customer service and a generous return policy. I could have gotten the JL Audio sub elsewhere for less but when there is a problem I would rather have Crutchfield by my side.
Pros:
Small and compact, fits under seat, included volume control works great, and only needs 10 gauge power and ground.
Cons:
Poor quality bass output, not very loud, plastic housing and aluminum woofer resonate and ruin the bass, doesn't hit very low for a subwoofer.

This little unit added the exact amount of bass I wanted. This will not rattle your tag, but great for a little something extra to your music. Very small and compact, super easy to install. At the time I ordered this unit, it came with an amp installation kit which was nice as well.

sound ordnance b-8ptd

Crutchfield Customer Review (What's this?)
 
This unit made the system in my 2008 tundra sound like I spent thousands of $'s on it. I'm 54 years old and love the old southern rock. I hear different parts in the songs now that I have never heard before until I installed the new sub. I put the pioneer AVH-x5500BHS Receiver, 6 3/4" polk speakers, the pioneer gm-a4604 amp, and of course the sub. To my ears, this is the best sounding system I have ever had. I bought the system over a 3 year period and of last week finished it. I bought all of it from Crutchfield, there support is second to none.
Pros:
The unit fit's under the back seat of my 2008 tundra. It's very easy to install and sound's like a much bigger unit.
Cons:
None

Sound Ordnance B-8PTD

Crutchfield Customer Review (What's this?)
 
It added a little bump in my music. Don't expect to put it in a trunk and be able to hear it. It needs to be in the cabin of the vehicle to make a difference. Too compact for my liking, it sounds a little dry and not very deep. It is pretty good for what it is though just not enough bump for me. I sent it back and got an enclosed 10" jlw3v3-2 instead.
Pros:
Compact, Nice for its size.
Cons:
Not enough thump for me.

I am very surprised for the size the quality of sound coming from the 8 inch compact sub. More than enough power for my single cab pickup. Very pleased with the product for the price.
Pros:
Great compact size, takes up very little room.
Cons:
Would of like some way to mount the sub down, nothing sent with the package.

Great unit. Deep sound and fits great under the seat in my Bronco II. I was worried about the sound quality. Then I was blown away by the sound. This is a great unit for small to mid size vehicles. It hits hard enough to rattle my glass but I am not one to blast my stereo like that you will love this unit. I plan on buying another for my Jeep Wrangled. Buy it you will love it.
Pros:
Deep base sounds and fits in tight places
Cons:
Non so far

Installed it in my 2006 Chevy Crew Cab. Works great! Did not want BIG BASS, just enough bass to complement the 4 doors speakers. Is perfect.
Pros:
Performance and Price.

( Great Product) for the power 8" speaker that it is. It hits hard and gives good sound. Like some have said if you have gotten past shaken the windows out of the car then this will be a great for the added sound that it you are looking for.
Pros:
Gives great bass along with adjustable control knob.
Cons:
The free wire kit that was include with the sound ordnance works great other than connectors are too small for the ground and power wires

works great 07 silverado

Installed in 07 classic silverado. Speaker sounds great and adds perfect bottom end to oreviously installed kicker doir speakers. Only small issues were as previosly stated i had to buy 2 10 gauge connectors for battery and ground wires. Also the battery terminal connector had to be filed out a bit to make larger. No complaints at all for a free wiring kit! I installed under back seat in the middle abd still had plenty of space.
Pros:
Great sound for price
Cons:
None

Excellent sound from a 8" sub.
Pros:
Very loud, has a remote controller easy to install with a very long cable. Crutchfield usually gives you and installation wich works perfectly for small cars, Jeeps and pickup trucks.
Cons:
Did not fit under the seat of my 2013 Sentra. Other than that very impress with the sound quality coming out of it.

Crutchfield Customer Review (What's this?)
 
Sounds ok for what it is but quality seems sub-par, Power & ground mounting block screws stripped out when trying to tighten wires with little or no effort I would recommend the Sound Ordnance B-8P over this one, much better quality & better sound
Pros:
Very compact
Cons:
Wire Block very cheap & piece of velcro included to hild in place does not work

I was looking something that would add some bass to my system without the space required for traditional subs. I like the size of this unit, but I was worried about the 8 inch woofer sounding ok. My worries are gone, it sounds great. There are some lows it just can't hit so if you are looking for big bass, this isn't for you. But it you are looking to balance out your factory sound, it is perfect.
Pros:
Size, sound, remote adjustment
Cons:
none

Sounds Like a Small & Inexpensive Sub - Go Figure

Written By Spencer, Knoxville, TN on Sunday, January 05, 2014
Crutchfield Customer Review (What's this?)
 
I recently installed this sub along with a new receiver to replace the OEM head unit in my 2003 Tacoma Double Cab. I went with this as an inexpensive option for a sub behind the back seat without buying a vehicle-specific enclosure. It fits fine, and nobody will ever know it's there; unfortunately, that includes me. After doing some sound testing, here's my opinion:

This sub is not very powerful. I'm biased coming from two Infinity 10s powered by 900W in my previous vehicle, but this sub does not fill out the low-end bass like I was hoping. Before you buy, do some sound testing on your current system. If your system is really missing out on frequency response from 50-120Hz, then this sub will fill out your sound nicely, but so would a set of decent component door speakers. This sub will not make your bass much louder, and it definitely won't make it feel much more powerful. IF YOU CRAVE THE POWER OF FREQUENCIES FROM 20-60Hz, SUCH AS IN HIP-HOP OR DUBSTEP, THEN YOU SIMPLY NEED A BIGGER AND MORE POWERFUL WOOFER. A great sub should have relatively even sound levels from ~20-180Hz, and this one is nowhere near even. This sub is really "punchy" from about 60-100Hz, which is fine for most rock or alternative music. Anything below 60Hz and it is really quiet. Anything above 100Hz and the sound is drowned out by the door speakers. Hopefully it improves as it breaks in, but my suggestion to you is either (1) buy a better sub, or (2) buy nice door speakers and forget the sub.
Pros:
Easy installation Price Punchy bass (pro or con depending on expectations)
Cons:
Poor frequency response below 60Hz. Almost no frequency response below 40Hz. Quiet in lower frequency range. Too loud in mid-bass frequencies. Poor at amplifying bass in hip-hop or dubstep music. Uneven frequency response and sound levels from 20-180Hz

Nice product, works as described

Written By MarkH, Punta Gorda, FL on Sunday, January 05, 2014
Crutchfield Customer Review (What's this?)
 
Purchased this for my son's 1993 Chevrolet standard cab pickup. The factory speakers had ZERO base response and this item did the trick. Slid it under the driver's seat and we now have a great "modern" sounding car stereo. It sounds about as good as my 2007 Chevrolet stock stereo system. We weren't interested in window rattling bass, just good sounding, slight bass feeling stereo and this was the perfect addition to do it. I would recommend this to my friends.
Pros:
straight forward installation, easy to install and place in vehicle
