Our take on the Sound Ordnance™ B-8PT

by Dominic Devito
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.

The Sound Ordnance B-8PT powered subwoofer turns the hard-to-fit spots in your vehicle into potent bass bastions, adding warmth and punch to your favorite music. You can fit this compact low-frequency factory under your car seat or in an out-of-the-way location in the cab of your truck. Preamp- and speaker-level inputs allow convenient connection to just about any system, plus you can tweak the phase control, bass boost, and low-pass crossover for maximum firepower in your vehicle. A wired remote lets you take command of your bass from the driver's seat.

The B-8PT's built-in amplifier sends 120 watts RMS to the 8" subwoofer, adding high-impact low notes that'll fortify your music. The Sound Ordnance logo means you'll get more than tremendous value and reliable performance — the B-8PT is reinforced with a 3-year warranty so you can add it to your system with confidence.

Comment by Robert Ferency-Viars Staff Writer - Creative,

Added much-needed bass to my daily commute!

Written by Robert Ferency-Viars, Staff Writer - Creative, on 12/21/2011 12:41:00 PM

I recently added the Sound Ordnance B-8PT powered sub to the back of my car, a Nissan Versa, and I'm very happy with it. It's just the right amount of bass for me, and I immediately started hearing notes that I'd never heard in my car before. If I turn up the sub, it booms really well - it's not shy! But I like my bass tighter and more focused, so I have the gain set about midway to keep it under control. It's great! The remote control knob lets me turn it down when my sons are in the car, so they don't have to put up with the pounding bass.

Only so-so

Written By Matt.C., Vancouver, WA on Thursday, December 19, 2013
Crutchfield Customer Review (What's this?)
 
I expected better. Not a super bone-jarring, fat-jiggling mega bass, but certainly a tighter thump than the muddy rumble that now sits behind my seat. You can do better, so keep looking... I got this to fill out the low-end in my commuter car (very short commute) without spending a lot or using up valuable space. Doesn't so much do that for most music as wash out the low-end with either too much rumble or not enough bass. I intended this to go under the passenger seat of my Subaru Outback, but it does not fit--even though it was supposed to. So, it now sits behind the seat and under the floor mat, so mostly hidden, but I do need to remove it on rare occasions when I have three passengers. I probably should have returned this but that felt like giving up on ever getting bass in that car without a lot more effort and expense. I did find that turning this thing upside down and playing a lot with the phase greatly improved the sound. I had to make a little stand for it so there is about a 1.5" gap between the floor and the speaker grill. I have really liked the Sound Ordnance amplifier I have (M-4075). Just a fantastic value and still can't believe the power I get from the bridged rear channel to a subwoofer. Dang, wish I could have done that for this car.
Pros:
small(ish) package with integrated amp sounds way better upside down
Cons:
doesn't sound near enough as good as it should not as small or thin as you might think

Sound Ordnacne B-8PT

Written By Mike, Daytona Beach FL on Monday, September 30, 2013
Crutchfield Customer Review (What's this?)
 
Perfect little Sub. I wanted a bit more bass without major cost or having to install an amp and a sub unit. This was the perfect solution. It is installed behind the passenger seat of a 2001 Mazda MX-5 and the fit is perfect. Installation was very easy since the battery is in the rear of the car. Great little box!!!
Pros:
Size, ease of install, flexibility with the remote volume control, sound quality is great
Cons:
not booming bass

What?!

Written By Jerry C, Jacksonville, NC on Saturday, August 10, 2013
Crutchfield Customer Review (What's this?)
 
For what this thing is, I was amazed at the quality of sound that came from it. I have to be honest, when my advisor recommended this, I was skeptical. However, the price was low enough and the Crutchfield return policy is good enough to give it a try.

My equipment: I'm running this from a Kenwood KIV-BT901head unit in a 2005 Dodge Ram 1500 Quad Cab using the RCA sub out and the amplifier power control wire. Anyone who knows anything about a Dodge Ram 1500 Quad Cab is that there is a very limited space to install equipment. Your options are a form fit sub box under the back seats or under the drivers seat. Dodge put the tire repair jack under the passenger seat.

This fit perfectly under the drivers seat. I ran a 6" ground from the drivers seat rail bolt and all the wiring through the precut hole in the carpet for the power seat controls.

The sound: It's not a competition band pass box, so don't expect super lows and nosebleed bass. Once I set the subwoofer crossover information on my head unit (80Hz@ 18dB/octave slope), I followed sound ordinance's guidance for setup. The sound is amazing for what I listen to (Metal, Hard Rock, and some more Pop type stuff when my wife is in the car). It compliments my highs/midrange well and doesn't distort at high volumes.
Pros:
1. Extremely small size fits great under my trucks driver seat; 2. Easy install and setup; 3. Affordable bass addition
Cons:
Looking at this item for what it is and what it is intended for, I can't legitimately find anything wrong with it. The manufacturer clearly states the frequency range at 80-200Hz which is not deep bass. Understanding this will give you a better idea of what you're buying. Compare it to a really nice computer subwoofer but better.

Just what I was looking for

Written By T1no33, Tampa, Fl on Monday, June 10, 2013
Crutchfield Customer Review (What's this?)
 
If you're looking for earth shattering bass that people hear a block away go buy something else. If you're looking for a great little powered sub to enhance the sound quality in your vehicle and get that extra punch out of things this is EXACTLY the product you are looking for. I am a 42 year old man that enjoys, rock, metal, country, hip hop, jazz, etc, etc and I found this little sub to make it all sound that much better in my vehicle. I have also NEVER installed anything in any vehicle I've owned out of fear but this was truly easy. I had to call Crutchfiled Support once and they were AMAZING!
Pros:
- easy installation - good price - good bass for unit
Cons:
- didn't fully fit underneath my car seat

Good sound and fits into small spaces

Written By No hardware included to mount unit!, Illinois on Sunday, June 02, 2013
Crutchfield Customer Review (What's this?)
 
I needed a small powered subwoofer to install in a 370z Roadster. This one was just the right size but still not able to fit under a seat. I was very surprised to find that there was absolutely no hardware included to actually mount the unit. I'm assuming that they figure you will just press fit it under your seat.
Pros:
Nice tight base sound.
Cons:
No mounting hardware. This should be noted in the description.

New 8" sub

Written By SimonSays, Armed Forces, AE on Sunday, June 02, 2013
 
First, I have been impressed with Crutchfield's aftercare. I called for help and the technician was excellent. The product has been great. Very simple install, easy setup and a pleasure to listen to in the car. So far, I would recommend this product.
Pros:
Size, price and easy to install. It rounds out factory speakers pretty well.
Cons:
If you enjoy bone rattling low bass, this is not for you; however, if you have a daily driver with children, and a passion for music, then this is for you. Super low bass just is not there.

perfect addition

Written By Rick M., Sartell, MN on Wednesday, May 22, 2013
Crutchfield Customer Review (What's this?)
 
Paired with the current system I installed myself thanks to Crutchfield's Master Sheets (Alpine CDE-HD138BT receiver Boston Acoustics SC 65 front 746 back) in my 2000 Silverado. It is the perfect compliment to an already quality sound system with hard, clean, steady bass. Placed in the back, under the seat, it is neatly hidden, but lets the listener know immeadiately that it means business.
Pros:
Small compact powerful priced right
Cons:
none
