MB Quart 6x9" Rear Speaker Upgrade for Jeep Wrangler JL 18-23/Gladiator JT 20-23

Upgrade your Jeep's sound system with the MB Quart Coaxial Rear Speaker Upgrade, a rear speaker kit engineered specifically for Jeep Wrangler JL and Gladiator JT models. This package includes a pair of 6x9-inch coaxial speakers with high-quality 1-inch magnesium dome tweeters and lightweight mica-blended paper cones, delivering full-spectrum sound with superior clarity and punchy bass. Designed as a direct-fit OEM-style replacement, these speakers enhance your audio without altering your Jeep’s interior aesthetic.

Experience vibrant, high-fidelity audio thanks to a 45Hz–23kHz frequency range, 86dB sensitivity, and a 6dB high-pass crossover that balances frequencies for distortion-free sound. With 110W RMS / 220W max power handling, you get consistent, powerful audio for every drive—on-road or off.

Installation is simple with included vehicle-specific wiring, plug-and-play OEM connectors, and a custom powder-coated mounting plate. Even better, matching rear speaker grilles preserve your factory look while hiding the upgraded power behind them.

Built to endure the rugged demands of Jeep life, the Rear Speaker Upgrade speakers combine durable materials and smart design—like the removable tweeter phase lens for personalized sound dispersion. Whether you're tackling trails or commuting, this upgrade delivers a premium audio experience built for adventure.
