Upgrade your Jeep’s sound with the MB Quart MBQJL-302 Tailgate Subwoofer System, engineered specifically for Jeep Wrangler JL (2018+). This 400-watt powered subwoofer is designed to deliver deep, powerful bass while preserving valuable interior space by mounting directly to the tailgate. Built with Jeep owners in mind, this subwoofer kit transforms your audio system with low-end impact that enhances music clarity on any road or trail.
At the heart of this system is a 12-inch woofer housed in a custom ported enclosure. Tuned for Jeep cabin acoustics, it delivers low-frequency response from 24 Hz up to 500 Hz, filling in the bass that factory systems often lack. Power comes from a dedicated 400-watt Class-D compact amplifier with on-board equalization, providing high-efficiency output and balanced sound performance. With a sensitivity rating of 86.6 dB, this tailgate subwoofer ensures strong, clean bass even in open-air or off-road conditions.
Installation is quick and straightforward thanks to plug-and-play OEM-style harnesses and vehicle-specific hardware that eliminates the need for custom fabrication. The system is designed to work seamlessly with MB Quart’s full Jeep audio ecosystem, offering plug-and-play compatibility with Stage 4 Wrangler JL systems or Stage 2 Wrangler JK systems for complete full-range sound coverage.
Durability is built into every component, from the rugged composite enclosure to the powder-coated amplifier plate, ensuring reliable performance in demanding Jeep environments. Measuring 35 x 17 x 10 inches, this system offers a perfect balance of size, power, and installation ease. Backed by MB Quart’s legacy of German engineering, the Tailgate Subwoofer System is the ideal solution for Jeep owners who want powerful bass, precision sound, and long-lasting reliability.
