Upgrade your truck's audio system with this premium custom-fit, quad 8-inch subwoofer enclosure, engineered specifically to fit perfectly under the rear seats of 2007 to 2026 GMC Sierra and Chevrolet Silverado Crew Cab trucks.

Utilizing a highly efficient front-firing design to house four 8-inch subwoofers, it is built to move massive amounts of air and guarantee an incredibly deep, loud, and responsive low-end punch.
Built to withstand extreme acoustic pressure and the wear-and-tear of daily use, this enclosure features heavy-duty construction with pre-installed baffle material to eliminate power-robbing box resonance. The exterior is beautifully wrapped in black aviation-grade carpet on the top and bottom, complemented by premium black faux leather on the front and sides for a sleek, custom look.
