Sound Ordnance's rugged Bass Bunker enclosures come built to last and ready to help your sub deliver real low-frequency firepower. These unloaded boxes feature high-grade, medium-density fiberboard construction, with sealed inner braces that help combat resonance by reducing vibrations. Rounded outside corners and recessed panels allow them to fit into more vehicles, while tough black carpeting defends against incoming nicks and scratches. Bass Bunkers make a great solution when building your own box is not an option.

The BB10-75S sealed enclosure holds one 10" subwoofer and offers an internal volume of 0.76 cubic feet. Just add the right sub, amp, and wiring, then mount the enclosure securely, and you're ready to hit the road with some real bass artillery in your arsenal.

Warning: This enclosure does not include mounting hardware. If you're buying a sub from us, please check "What's in the Box?" to see if screws are included. If not, you should have an assortment of heavy-duty wood screws on hand for the installation.

Product Highlights:

  • sealed hatchback style enclosure for one 10" subwoofer
  • 5/8" MDF (medium-density fiberboard) with black carpet covering
  • cutout size: 9-1/4"
  • internal volume: 0.76 cubic feet
  • dimensions: 14-1/8"W x 13-7/16"H x 11-5/8"D1 x 8-1/2"D2
  • warranty: 1 year
  • Our 60-day money-back guarantee

Why do I need an enclosure?

An enclosure is simply the box that houses your sub; sealed and ported enclosures are the most popular types. A sealed enclosure is usually smaller in size, sacrificing a little volume level to deliver more accurate bass. The ported enclosure features a vent which allows bass waves to escape from behind the mounted sub, augmenting the bass coming off the front of the sub. Ported boxes are louder, bigger, and a little less accurate. Every sub works best in the size and type of enclosure that's recommended by the manufacturer, so make sure you match your sub with the right box.

Excellent product! Arrived on time as expected with any Crutchfield purchase. Suited my needs for a 10" subwoofer just fine. Easy to connect and hook right up to the amplifier! Jeep JK sounds better already!



Small, strong, well built!

Crutchfield Customer Review (What's this?)

Great little box. Fits snug against my hatchbacks back seat back. (that's a lot of back!) Very well built, very durable and looks great. The terminals on the back of the box protrude just slightly, so keep this in mind when placing it on a surface that might get scratched when installing the driver/woofer.

Pros: Small, strong, well built

Cons: terminals protrude from back and could scratch surfaces when installing the driver/woofer

Nice enclosure

Nice looking enclosure, built solid and fits nicely in the back of hatch back.

Pros: Nice carpeting on the outside to blend in with natural flow of the cars carpeting.

Cons: The curvature limits possible mounting positions.

Worked great!

Crutchfield Customer Review (What's this?)

I had a old 10 inch Alumapro Subwoofer that I wanted to put to use. I bought this box and it fit perfectly. It doesn't take up very much space in my trunk (Toyota Corolla). Good bang for your buck

Pros: Worked as described, inexpensive

Cons: None

Bass Bunker Is Fantastic

Written by: tpmvabch from Virginia Beach, VA on February 24, 2014

Crutchfield Customer Review (What's this?)

Solid enclosure. Very well made. The binding posts are easy to use and good quality. Bought this at the advice of a Crutchfield adviser an he was spot on with the recommendation. The unit sits in the back of a Nissan Xterra which is somewhat of a rough ride. No doubt this enclosure will hold up. You won't be disappointed.

Pros: Solid. Well made.

Cons: None

Crutchfield Customer Review (What's this?)

had a 10" MTX gathering dust and decided to put it to use. got the box from the outlet, a speaker had been put in previously, so there were already screw holes. luckily they matched my woofer. installed in 5 minutes and playing. works great, wish I had a better woofer, but a sub and box for this price is hard to beat! this box is well made and looks good. I like the binding posts, they are good quality.

Pros: easy sub box reasonable price good value good quality

For not knowing much about subs and bunkers along with the whole 9 yards, I'd say I'm satisfied. The sub fit nicely into the bunker a good friend of mine strapped it fast to the back of my vehicle.

Pros: Fits nicely and doesn't take up a lot of space.

Cons: None.

Small box. Great value.

Crutchfield Customer Review (What's this?)

I was a bit worried at first that this box was only 5/8 thick, but once I hooked it up to a Polk db1040 and a boston 300 RMS amp it put my worries out the door. I am impressed with the quality and durability of this box. I highly recommend this unit for any style woofer, you will not be disappointed.

Crutchfield Customer Review (What's this?)

the box is good quality and good construction but I've realized after installing it
that I need a ported box over a sealed due to the lack of bass.



Great Box!!

Crutchfield Customer Review (What's this?)

I used this box for an Infinity Kappa 100.9w. Between the combination of these 2
products, the sound coming from my trunk can only be described as incredible!! The
bass hits hard and all that is back there is a single 10".

Crutchfield Customer Review (What's this?)

I have been updating the sound system in my Sequoia over the last couple of months. Before I could get the sub box built, I scheduled a week long photo safari to Florida. I saw an add in a Crutchfield catalog for this series of pre-built cabinets. After talking to a helpful Chrutchfield advisor, I ordered this model. With free shipping, I got it in 2 days. The box is well built and nicely covered. It comes with a recessed connector cup installed that will accept several types of speaker wire terminations. It is doing the job very nicely, and I am greatly enjoying my new system on my trip.
