MB Quart Rear Soundbar, 8" Speakers, Jeep Wrangler JL 18-23/Gladiator JT 20-23

Upgrade your Jeep’s audio experience with the MB Quart MBQJ-48HRGB Rear Soundbar, engineered specifically for Jeep Wrangler JL (2018-2023) and Gladiator JT (2020-2023) models. Designed as a direct replacement for the factory rear soundbar, this system delivers powerful sound while fitting seamlessly into your Jeep’s interior. With plug-and-play OEM-style harnesses and a lightweight composite enclosure, installation is quick and simple with no custom fabrication required.

This rear soundbar is loaded with (4) 8-inch compression horn speakers paired with 1-inch titanium dome tweeters, delivering strong midrange performance and crisp high frequencies. Built with Y30 iron ferrite magnets, the drivers provide distortion-free audio that maintains clarity even at higher volumes or in rugged off-road conditions. Tuned specifically for Jeep cabins, the rear soundbar ensures immersive surround sound that enhances both music and voice clarity on every adventure.

Performance meets power with a frequency response of 20 Hz–24 kHz and 180 watts of peak handling. This wide range ensures deep, punchy bass, detailed mids, and crystal-clear highs that cut through wind and road noise. Integrated RGB LED lighting shines through the translucent speaker grilles, adding a custom look and vibrant color accents that elevate your Jeep’s interior style.

Durable enough for off-road conditions, the rear soundbar uses a rugged composite frame and powder-coated grille construction to withstand the elements. Designed to work seamlessly with MB Quart Stage Jeep audio systems, this soundbar is the perfect upgrade path for Jeep owners looking for a rear-channel solution that combines superior sound, rugged durability, and show-stopping style. Backed by MB Quart’s legacy of German audio engineering, it delivers precision sound and long-lasting reliability built for Jeep life.
