Product Overview
6.5” Soundbar Upgrade Kit for Jeep Wrangler JL / JLU & Gladiator JT
DS18’s JL-SB6 delivers a high-performance soundbar upgrade replacing 4” speakers with premium 6.5” neodymium midrange speakers and 1” dome tweeters. This kit gives your Jeep the presence it needs to get LOUD on the trail or freeway!
Jeep-Ready Performance
Designed for a perfect fit in Wrangler JL/JLU and Gladiator JT models, every kit includes a precision mounting template and hardware to guide your install.
Premium Build for All Conditions
Made from injection-molded ASA composite: the JL-SB6 resists heat, impact, and UV damage, so it can handle anything your Jeep does. The NEW steel grille keeps your speakers protected and adds a clean, aggressive look. Plug-and-play connectors make wiring seamless, and with both left and right side upgrades you get a complete soundbar transformation.
