Cruisin' in the Crew Cab

Kicker's Solo-Baric® square-cone subwoofers have delivered amazing bass for decades. Now their compact L7T subs bring that great bass to your truck, mounted in an enclosure specially designed to tuck under your GM crew cab truck's rear seat and deliver optimal low end in a confined space. Match it up with a beefy amp — the 51KGMDL7T122 can handle a stunning 1200 watts of RMS power.

Still hip to be square

This enclosure features two of Kicker's 20646LT124 L7T shallow-mount 12" subwoofers wired to a single terminal at 2 ohms total impedance. The signature square cone offers up to 20% more surface area than a conventional round sub to move more air and deliver more bass, while the Santoprene rubber surround and steel frame offer solid support. You'll get more bass from a shallow sub than ever before.

A box as tough as your truck

The 51KGMDL7T122 enclosure is constructed of heavy-duty 3/4" MDF with heavy internal bracing and covered with tough black carpet. The design process combines computer modeling and human fine-tuning for the best of both worlds. It's contoured for a perfect fit beneath the rear seat of your truck to save space and preserve legroom.

This enclosure is designed for a perfect fit in 2008-18 Chevrolet Silverado and GMC Sierra Crew Cab trucks under the rear seat. It will fit 2019-up models, but not as precisely. Items such as power inverters, storage compartments, spare tire tools, or floor mats stored under the rear seat may require removal.
