SoundBox Silverado/Sierra Double Cab (Extended) 2014-2018 Single 12" Subwoofer Enclosure

Really shallow, very limited on selection of shallow mount subwoofer that can be used. I mounted a DS18 shallow mount that barely fit in there. The box has too much wasted space for the standing base. It uses about 2 inches that could've been used for inner space. Over all it fits perfectly under my 2016 GMC sierra Double cab and the subwoofer sounds ok. Wish they made a down firing box.

Great and simple, fit perfect. Sounds great for what it was intended

Box looked good but was not sealed. Half was sealed and the other half allowed air to escape .

I own a car audio store and i couldn't find this with any of my distributors. Sure enough, Amazon had it. And for a great price. It is a very solid and well made box, fit perfectly in the vehicle. Customer was very happy with this product.
