Adding bass to a truck can be a very complicated problem to tackle, especially when building a box! We offer pre-built enclosures that are ready to be dropped into your 2007-2013 Chevy Silverado crew cab truck that offer unbeatable performance and sound quality that simply cannot be matched. This is a dual 12" down firing model, why down firing? This style enclosure actually increase the SPL output of your subwoofers forcing the sound waves to travel up in down inside the cab before reaching the listener. The woofers are spaced off the floor so it's not possible for them to hit the floor while playing. It also keeps the subs out of view for security concerns. Overall you cannot find a better fitting or sound box at this price! Our boxes are made from precision cuts of MDF. They are then liquid nailed, nailed and completely sealed. We then wrap them with high quality carpet that matches most vehicle interiors. All Boxes feature high grade spring loaded terminal cup(s) for the absolute best connection possible. All the custom series enclosures are made to fit precisely into your 2007-2013 Chevy Silverado crew cab truck to the get the max performance from every extra inch of wasted space. We guarantee you will not only see a difference in the quality of the boxes we build, but you will hear the difference and that is what is it is truly all about.
