Two 12-inch Solo-Baric L7T subwoofers, formed into a cabinet that fits the rear floor of a Chevy Silverado or GMC Sierra Crew Cab from 2008 forward. It installs under the back seat, so cab space and rear legroom stay where they were.

Twelve-inch square cones give up to 20 percent more cone area than round subs of the same nominal size, and in a truck cabin that translates directly into output. KICKER pairs the cones with the largest voice coil and magnet used in a thin subwoofer, a redesigned top plate, a dedicated heat management system, and signature cone stitching for durability at high power.

The pair terminates at a single 2-ohm connection rated for 1,200 W RMS, so one mono amplifier handles the whole system. Frequency response runs 25 to 100 Hz.

Thick MDF with heavy internal bracing keeps the cabinet solid under pressure, and black carpeting protects it from cargo and boots. Dimensions are 52 inches wide, 7-7/16 inches tall, and 15-1/2 inches deep.

Fitment notes: this box is built for 2008-newer Silverado and Sierra Crew Cab. It also fits 2019-newer GM trucks, though not as precisely. Items such as inverters, storage compartments, spare tire tools, or floor mats may need to be removed.
