The MB Quart MBQJK-28C is a Jeep JK sound bar replacement for every 2007-2018 Jeep Wrangler JK: a rear overhead soundbar with two 8 inch coaxial speakers, a composite enclosure and interchangeable colored grilles, designed to directly replace the OEM rear speaker sound bar. It is plug and play with the factory-style connections.
The factory JK sound bar is a common weak point once the front speakers are upgraded. MB Quart's version puts two 8 inch coaxials with 1 inch titanium dome tweeters overhead, in an enclosure that uses the roof area around the B-pillar. MB Quart's MBQJK-STG2AH-1 Stage 2 front system lists this soundbar (or a second set of JS1-216JK speakers) as its rear speaker option.
For Jeep JK speakers overhead, this Jeep Wrangler JK sound bar is the complete option: the Jeep JK rear speakers come installed in the enclosure. It pairs with Jeep Wrangler JK speakers up front, and as a Jeep sound bar it replaces the whole factory bar rather than only its drivers. This MB Quart soundbar is the Jeep soundbar version without lighting; the MBQJK-28CRGB adds RGB lighting.

Why MB Quart
MB Quart builds vehicle-tuned audio packages for the Jeep Wrangler 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.
Finish Your Jeep Wrangler JK Audio Upgrade
Before ordering this Jeep JK soundbar, confirm you have a 2007-2018 Wrangler JK and decide how you will power it. For a complete JK system, pair it with the MB Quart MBQJK-STG2AH-1 Stage 2 front kit and, if you want bass, the MBQJL-302 tailgate subwoofer. Questions? Contact Dunes 2 Dezert SXS before you buy.
