Product Overview
The KICKER 51KJPL7T122 was engineered around one simple goal: deliver outstanding bass without taking over your Jeep's cargo area.
Instead of occupying valuable storage space with a traditional enclosure, this system mounts directly to the inside of the tailgate, allowing you to enjoy powerful bass while maintaining the versatility that makes the Wrangler such a capable vehicle.
At the heart of the enclosure is KICKER's renowned 12-inch Solo-Baric L7T shallow-mount square subwoofer, designed to produce impressive low-frequency output from a compact mounting depth. The weather-resistant roto-molded enclosure is built to withstand the demanding environments Jeep owners encounter, making it an excellent choice for both everyday driving and weekend adventures.
The L7T Advantage
KICKER's Solo-Baric square subwoofer design has become legendary for one simple reason—more cone area.
Compared to a conventional round subwoofer of similar size, the square Solo-Baric cone provides up to 20% more effective cone area, allowing it to move more air for stronger bass performance.

Pro Audio Center Tip
One of the biggest advantages of the 51KJPL7T122 isn't just its bass performance—it's where the enclosure is mounted.
Traditional subwoofer boxes often occupy valuable cargo space that Jeep owners depend on for tools, recovery equipment, camping gear, and everyday storage.
By mounting to the inside of the tailgate, this enclosure delivers impressive low-frequency performance while helping keep the cargo area open and usable—a major advantage for customers who use their Wrangler for both daily driving and adventure.
