The MB Quart JC1-108 is a pair of Jeep Wrangler dash speakers for 2018-current Wrangler JL and 2020-current Gladiator JT: two 3.5 inch coaxials on stamped steel frames with OEM plug wiring that fit the front upper dash or the rear soundbar locations. They are a direct, plug-in Jeep Wrangler speaker replacement.
Small factory 3.5 inch speakers handle much of the vocal and high-frequency detail you hear from the dash. This kit replaces them with MB Quart coaxials and an OEM adaptor plug, with no wire splicing.
The same pair serves as Jeep JL dash speakers or as small Jeep Wrangler speakers in the rear soundbar. As Jeep Wrangler 3.5 inch speakers they also fit the Gladiator, so they work as Jeep Gladiator speakers and a simple Jeep Gladiator speaker upgrade. If you are comparing Jeep speakers and Jeep JL speakers for the dash, these are 3.5 inch coaxial speakers built for the factory locations.

Why MB Quart
MB Quart builds vehicle-tuned audio packages for the Jeep Wrangler JL and Gladiator JT, 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 JL Dash Speaker Upgrade
Decide whether you are upgrading the dash, the rear soundbar or both, and order one kit per pair of locations. If you plan to add amplification later, look at the MB Quart Stage 4 systems first, since they include their own dash speakers. Questions? Contact Dunes 2 Dezert SXS before you buy.
