Kicker 51KJPL7T122 L7T 12" Tailgate-Mount Loaded Subwoofer Enclosure 2Ω for Jeep Wrangler JK/JL

Kicker 51KJPL7T122 is a Jeep-specific L7T loaded subwoofer enclosure designed for many Jeep Wrangler JK and JL applications. This system uses a large 12-inch Kicker L7T ultra-thin square subwoofer in a front-firing tailgate-mount enclosure to deliver strong, space-saving bass without using a traditional cargo-area sub box.

The custom tailgate-mount enclosure and included hardware are designed to retain cab space and legroom while giving Wrangler owners a cleaner, vehicle-specific bass upgrade path than a universal enclosure.
