MB Quart Rear Overhead Soundbar For 07-18 Jeep Wrangler JK, Dual 8" Speakers - 431777

Upgrade your Jeep Wrangler JK’s audio system with the MB Quart Rear Overhead Soundbar, designed specifically for 2007 - 2018 models. This premium, tuned soundbar is a direct replacement for your factory rear speaker system, delivering a seamless fit while dramatically enhancing sound quality. Built as a drop-in upgrade, it utilizes the roof space around the B-pillar, preserving your Jeep’s interior look while maximizing audio performance.

Equipped with dual 8-inch coaxial speakers, this soundbar produces powerful, full-range sound with impressive clarity and depth. Each speaker features a 1-inch pure titanium dome tweeter, delivering crisp highs and detailed audio reproduction. With 140 watts of peak power handling (70W RMS per speaker), the system maintains distortion-free performance even at higher volumes. A wide frequency response from 25Hz to 22kHz ensures every note is heard—from deep bass to bright highs.

Advanced audio engineering enhances your listening experience. A 12dB high-pass crossover optimizes frequency distribution between woofers and tweeters, creating a balanced and immersive soundstage. High 92dB sensitivity ensures efficient power usage, delivering louder sound with less strain on your system. Durable materials, including a composite polypropylene cone and butyl rubber surround, ensure consistent performance in varying conditions.

The lightweight composite enclosure maximizes internal airspace for improved acoustics while maintaining strength and durability. A Y30 ferrite magnet provides reliable, high-output performance, and the integrated MB Quart logo adds a clean, stylish finish.

Installation is quick and easy with a plug-and-play OEM-style design. Customize your look with interchangeable grilles and enjoy enhanced sound on every drive.
