Brand

Take your Jeep’s sound system to the next level with the MB Quart MBQJ-STG4AH-1 STAGE 4 Audio Upgrade Kit, engineered exclusively for Jeep Wrangler JL (2018-2026) and Gladiator JT (2020-2026). Designed for aftermarket radios and requiring a rear speaker kit or soundbar for full coverage, this complete upgrade delivers powerful, balanced, and precise sound performance on any road or trail.

This all-in-one kit includes a 4-speaker set with premium components: two 3.5-inch coaxial speakers with 0.75-inch magnesium dome tweeters for crisp highs, and two 6.5-inch midbass drivers with polypropylene/mica blend cones for strong midrange response. The system is powered by dual 400-watt NA2 Class-D compact amplifiers with on-board equalization, producing 800 watts of peak output in a high-efficiency, compact design. With optimized crossover networks (12dB midrange / 6dB tweeter), every detail is tuned for clarity, depth, and full-range audio that cuts through road noise and outdoor conditions.

Built for rugged environments, the MBQJ-STG4AH-1 features durable composite mounting enclosures, a powder-coated amplifier plate, and high-quality speaker materials designed to withstand demanding Jeep and truck use. Installation is fast and simple thanks to plug-and-play OEM harnesses and factory-specific mounting, eliminating the need for custom fabrication while ensuring a seamless fit in factory locations.

With a frequency response of 75 Hz–23 kHz, sensitivity of 89 dB, and a black finish that blends with Jeep interiors, this kit provides both performance and style. Dimensions measure 22.24 x 18.34 x 10.59 inches with a total weight of 25 pounds. Backed by MB Quart’s heritage of German engineering, the STAGE 4 Jeep upgrade kit delivers reliable power, premium sound quality, and long-lasting durability for your vehicle.
