51KGM2DL7T122 KICKER Dual 12" L7T Subwoofer Enclosure for 2019–2027 Chevy Silverado & GMC Sierra Crew Cab 1200W RMS 2 Ohm

KICKER 51KGM2DL7T122 — Updated GM-Specific Dual 12" L7T Subwoofer Enclosure

Bring serious bass to your newer Chevy Silverado or GMC Sierra with the KICKER 51KGM2DL7T122, an updated, truck-specific enclosure designed for 2019–2027 GM 1500 Crew Cab models.

Building on the proven concept of KICKER's original GM-specific dual L7T enclosure, this updated design addresses under-seat fitment in newer trucks. Its improved shape fills more of the unused space beneath the rear seat, helping create a cleaner, more integrated installation than the previous-generation enclosure.

The updated enclosure also provides more internal box volume for improved audible bass, making it an appealing upgrade for truck owners who want impactful low-frequency performance without giving up the space needed for everyday use.

Loaded with two KICKER Solo-Baric L7T 12-inch square subwoofers, this system combines KICKER's signature square-subwoofer design with a vehicle-specific enclosure built around the contours of newer GM Crew Cab interiors.

Designed for Chevy Silverado and GMC Sierra 1500 Crew Cab trucks, the 51KGM2DL7T122 is a purpose-built solution for adding substantial bass while keeping the installation tucked beneath the rear seat.
