Our take on the Sound Ordnance™ B-8P

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-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 B-8P's built-in amplifier powers the sub with 80 watts RMS for surefire response, and you can use the variable low-pass filter and phase control to tune the bass barrage for your vehicle.

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.

Big Sound Little Package

Written By Paul, Houston, TX on Tuesday, 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., Wailuku, HI on Monday, 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, Missoula, MT on Sunday, 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 myself...is this thing on? I was underwhelmed...so 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/DC...it 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

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

it was average

Written By Kate, Omaha, NE on Saturday, June 14, 2014
Crutchfield Customer Review (What's this?)
 
This was my first sub so I didn't really know what exactly to look for. When I asked the lady on here she told me this would have enough power for my little car but it really didn't. I was never satisfied. I would turn the power up but it never performed to my liking. Then one day it all of a sudden didn't really work anymore and I couldnt figure it out!! I asked 3 of my friends and no one knew. So I sent it back and have dreams of a real sub one day.
Pros:
small, confusing to others
Cons:
everything else

Big Sound on a Small Budget

Written By AudioDad, TN on Friday, 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, Pinole, CA on Tuesday, 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.

Very impressed, and here is why

Written By Patrick, State Center, IA on Sunday, April 06, 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, Toms River, NJ on Saturday, April 05, 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, Souh Florida on Thursday, April 03, 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.

very, very surprising

Written By Alex, Richmond, Va on Thursday, 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

Not a large amount of bass, but pretty good

Written By Matt, Westminster, SC on Thursday, March 06, 2014
Crutchfield Customer Review (What's this?)
 
Price vs Bass produced is definitely worth it. Finding an amp and sub for this cheap is impossible. The thump is noticeable but nothing crazy. I have had vehicles with 2 10" bandpass, and 2 12" ported, and this comes no where near that amount of kick. However, it is worth the 100 dollars if you want something small you can toss in your vehicle to add some bass. Hits some pretty decent lows.`
Pros:
Adds Thump, cheap price, worth the money
Cons:
big for an 8", not nearly as powerful as 2 12" like others say

Awesome boom for the buck!

Written By Tony L, Cincinnati, Oh on Monday, March 03, 2014
Crutchfield Customer Review (What's this?)
 
Wanted something small and affordable for my eclipse to liven up the sound some. I installed this and was blown away, it hits harder than i thought it would. Definitely recommend this to people who have a hatchback, suv or a truck that it will fit in. Way better than i thought it would be. Also if it helps, im running a jvc headunit with subwoofer preouts that has a built in subwoofer controller. I have sony 6 1/2 3 ways all around.
Pros:
Sounds awesome for an 8" subwoofer. The bass plays low and clear.
Cons:
Probably would not sound as good in a trunk styled car unless you fold the seat down.

Perfect for my 2 door coupe. It makes very clear bass for all the rock and little bit of hip hop that I listen too, and it is not overwhelming at high volume. Great sound, price, and easy to install with the kit from Crutchfield that came with it.

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

Amazing

Written By Tiny, San Jose ,CA on Thursday, February 06, 2014
Crutchfield Customer Review (What's this?)
 
I really couldn't ask for more in a sub. I'm a first time installer and it took me maybe 1 hour to put this in my car. A big chunk of that time was just finding where I could rout the power wire through the firewall. It gives off more than enough bass. It has about 9 levels I believe and 3 is enough for me. I'm an 18 yo guy and I listen to mostly rock and alternative. My friends have connected their phones with hip hop and rap and it still sounds great. If you want bass then this will work. If you want thunder I'm not so sure

Big. But not too big. Fits snug in the way back compartment of my Lincoln Aviator.

Big Bang, Little Buck

Written By TheMajekalBum, Longmont, CO on Thursday, January 09, 2014
Crutchfield Customer Review (What's this?)
 
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

Written By Homer, Jermyn, PA. on Wednesday, January 08, 2014
Crutchfield Customer Review (What's this?)
 
Overall a great powered sub! Im a firm believer in you get what you pay for. For the price, what more can you ask for. Powerful sound to give your stock system the bass it lacks, the extra bass you were looking to add, but do not want an over powering "bump". This deserves a 5 star all around. Built well, easy to wire, sounds great.
Pros:
Easy to wire, amp Is built right in! At 80 watts its not a strain on the electrical system, even after long bass runs, and hard repetitive hits. Very user friendly setting to get the bass sound best for you.
Cons:
Well I will start with the led lights, they are a little over the top. No worries there is a switch on the unit to shut them off. Produces great in the box, but personally not a fan of the see through plastic panel, the unit fits almost discrete in the back of my suv, but it seems to scratch rather easy with minor stuff brushing up against it. Those are the only two flaws I noted. The low end of bass hits, drops, and runs are distorted but keep in mind, lower powered 8 in. Sub will do that.

Nice bass boost that doesn't attract unwanted attention

Written By ksang, Reading, PA on Monday, December 30, 2013
Crutchfield Customer Review (What's this?)
 
I chose the B-8P because I wanted to add a low end to my system without sacrificing too much cargo space or attracting attention from potential thieves. I'm happy to report that this was the perfect solution! It adds a modest bass boost to your system, but if you're looking for punchy, car-rattling bass, you may want to consider other options.

I should also add that an amp wiring kit must be purchased separately to install this sub. I found a 10 gauge kit, and that worked just fine.
Pros:
Easy setup Enhances music without drowning out highs and mids Illumination can be turned on or off Great deal for the price
Cons:
No wiring included May leave something to be desired for bass junkies

Very pleased so far

Written By DanielM, Texas Hill Country on Monday, December 16, 2013
Crutchfield Customer Review (What's this?)
 
I'm happy with the sound, although because I installed it in my travel trailer, I really have to keep the level down, like WAY down. This thing could really pump out the bass. I was surprised by the size; I installed under a dinette seat in the storage area, and had to cut out one of the seat supports to drop it into place, then install a modified brace over it that lays in place, just in case the sub had to come out again.
Pros:
Really fills the sound out coupled with the tiny factory speakers.
Cons:
The instructions weren't all that clear. I fished speaker wire off the Speaker C outputs of the Jensen RV unit, and thought the high level input would trigger the sub, only to find that it still needs to have the 12V trigger, forcing me to take out the head unit and run another wire.

Awesome CX-5 Bose Enhancement

Written By Scott M, Smyrna ,TN on Sunday, 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

Bass

It did what Crutchfield said it would do, added bass to my stereo. For the price and ease of installation you will not find a better product, with my windows up it sound like I'm in a concert, very impressive, with the windows down sounds like a normal car stereo.
Pros:
ease of installation price
Cons:
little bulky for a 8"

Great product, even better when on sale

Written By Carter, Fayetteville, NC on Saturday, 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., Los Angeles, CA on Saturday, 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

Written By Matt B, Shreveport, LA on Saturday, August 31, 2013
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.

Written By james k, haleyville al on Saturday, August 24, 2013
 
Great little unit with big sound. Just wanted reasonable price to accent bass in music. If you are the type that wants to rattle your windows, move on. If you want good bass accents, a good price and a good looking unit that doesnt take up a lot of space, this is it.
Pros:
Special thanks to phone line help people that answered about 500 questions from me. Wiring kit and unit arrived as promised.

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

Powerful Little Sub

Written By Redsfan1973, Archbold, OH on Monday, August 12, 2013
 
I bought this powered sub for my son this past Christmas(2012). It was on sale for a great price and he has a small car(1997 Saturn SC2). He absolutely loved it after him and his buddies hooked it up. It is a great sounding bandpass. It sounds better than most his friends subs who paid a lot more money than what I paid. I am thinking about getting one for my truck. Very pleased and surprised with this sub. Thanks Crutchfield!
Pros:
Small sub with great power and sound
Cons:
None
