      Description

      Powerful Audio Enhancement. The Subwoofer Box delivers deep, rich bass and enhanced audio performance by providing an acoustically optimized enclosure for your sound system. Designed with precision for behind-the-driver’s-seat installation, it efficiently utilizes cabin space while maintaining powerful sound output. This box fits 2007–2013 GMC Sierra 1500 Crew Cab models and serves as a direct replacement for standard enclosures, offering improved sound quality and durability.

      Construction and Appearance. Built from 5/8-inch medium-density fiberboard (MDF), this subwoofer box provides superior rigidity and acoustic balance. The matte black polyurethane coated finish adds a sleek, protective layer that resists moisture, scratches, and wear. The ported down-firing design enhances low-frequency response while protecting the subwoofer from physical damage. With an internal air volume of 1.08 cubic feet and a port volume of 0.06 cubic feet, the enclosure delivers precise tuning and clean bass reproduction. Its compact dimensions—35 inches long, 11 inches wide, and 17 inches high—allow it to fit perfectly behind the driver’s seat without reducing legroom or comfort.

      Installation. Designed for easy integration, this subwoofer box installs directly behind the driver’s seat using basic tools. Professional installation is recommended for optimal wiring, subwoofer mounting, and sound tuning. The enclosure’s 6-inch mounting depth accommodates most standard 12-inch subwoofers, and the pre-cut opening ensures a perfect fit. Once installed, it provides an immediate improvement in sound depth, clarity, and bass response.

      Application. This Subwoofer Box fits 2007–2013 GMC Sierra 1500 Crew Cab models. Ideal for audio enthusiasts looking to maximize in-cabin acoustics, it delivers strong bass performance in a durable and space-efficient package. With its high-quality MDF construction, ported design, and sleek matte black finish, this subwoofer enclosure combines durability, precision, and aesthetic appeal for an elevated listening experience on every drive.
