Custom Dual 12″ 99-06 GMC Sierra Extended Cab Subwoofer Box
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 99-06 Chevy Silverado / GMC Sierra 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!
