The MB Quart MBQJL-302 is a 400 watt Jeep Wrangler subwoofer system for the 2018-current Wrangler JL and 2007-2018 Wrangler JK: a 12 inch high output sub in an enclosure that mounts to the interior tailgate panel, powered by a 400 watt Class D amplifier. It keeps the cargo floor clear and includes the mounting hardware.
MB Quart lists it as plug and play with any of its Stage 4 Wrangler JL systems or its Stage 2 Wrangler JK system; the amplifier mounts to the amp plate included with MBQJ-STG4A-1, MBQJ-STG4AH-1 or MBQJK-STG2AH-1. As a Jeep tailgate subwoofer, it is the 12 inch option; Wranglers with the factory premium subwoofer can instead use the MBQJL-SUBR-1 upgrade.
As a Jeep Wrangler tailgate subwoofer it fits both generations: a Jeep JL subwoofer for 2018+ and a Jeep JK subwoofer for 2007-2018, which also makes it the Jeep JK tailgate subwoofer in MB Quart's line. This Jeep subwoofer is the 12 inch subwoofer option and the Jeep Wrangler JL subwoofer that anchors a Jeep Wrangler sound system.

Why MB Quart
MB Quart builds vehicle-tuned audio packages for the Jeep Wrangler JL and JK, engineered around the factory mounting locations and wiring so the upgrade installs with basic hand tools instead of custom fabrication. MB Quart sells its Jeep kits in stages, so you can start with one piece and add matching speakers, subwoofers or a soundbar later.
Complete Your Jeep Wrangler Subwoofer Setup
Confirm whether you have a Wrangler JL or JK, then plan the amplifier mounting: an MB Quart Stage 4 (JL) or Stage 2 (JK) system supplies the amp plate, or choose the MBQJL-302-ACC-1 package for a factory-speaker JL. Questions? Contact Dunes 2 Dezert SXS before you buy.
