This custom mdf creation is the result of listening to what our customers really want in a box. It's an innovative dual 10 downfire box with a cool spot in the middle to mount your amp. Has a mounting depth of 6-1/2" and each chamber has .70 cu.ft. of air space. The amp shelf is approximately 18"W x 13"D. If you have a pair of 10s, but not a good spot to mount your amp, then this is the box for you. This box is a hot commodity for these trucks. In fact, it's our best selling chevy truck box period. Not only does it look and fit great, but it adds a whole new dimension of functionality. It pounds incredibly hard and everybody loves it. Nobody will believe there are only two 10s under your seat. This box is designed to fit perfectly under the rear seat with ZERO modifications. It will not affect the operation of rear seat at all. It will close and lock like normal.
I just received the box today and man is it awesome. It fits perfectly under my back seat and the subs fit perfectly in the holes. I filled up the boxes with some polyfil and it sounds awesome! the bass gets so low even my tailgate rattles. Best box I've ever seen. thanks! -Brian, Temecula, CA
I loaded it (ctb99-210amp) with Memphis Audio MClass subs, and powered them with a Fosgate Punch P600.2. The results were breath taking (literally), and when my rear view mirror fell off and some kids 3 blocks away showed up to see where the bass was coming from came over, well I was very impressed. On top of the sound and quality put into this box the fit was perfect the back seat still goes down far enough to latch and is easy to access the straps to release it to pull it up, the only thing I can really say is.............................YOU GUYS BUILD A KICK ASS BOX!!!
Thank you, Jack F. Customer for LIFE.. Emmett, ID
My new sub box looks and sounds great thanks to you and your company. I gotta say I wanted BASS and now I got BASS. The whole set up looks fantastic in my 03’ Silverado. I put two 10” Kicker CVR’s and a Kicker ZX400.1 mono amp in this baby and man does it thump. Phil M. Fort Worth, TX
