Transform your 2021–2026 Ford Bronco’s audio performance with the MB Quart Stage 6 Tuned Audio Package, an 800-watt, eight-speaker sound system engineered for Bronco models equipped with the OEM base audio system or an aftermarket source unit. Designed to deliver premium clarity, powerful volume, and immersive staging, this upgrade dramatically elevates your listening experience on or off the road.
At the front of the system is a true 3-way 6.5″ / 4″ component speaker setup supported by 1″ magnesium dome WideSphere™ tweeters for crisp, extended high frequencies. The midbass and midrange drivers use aerated pop paper cones blended with mica for strength, warmth, and accuracy. The speakers drop directly into the factory locations, with the tweeters mounting cleanly behind the dash speaker grilles.
Rear fill is handled by a pair of 6.5″ 2-way coaxial speakers, also equipped with 1″ magnesium dome tweeters for balanced sound imaging throughout the cabin. These mount securely in the rear pillar enclosures, replacing the factory hardware while maintaining a factory-clean look.
Powering the entire system are two compact yet high-output 400-watt Class-D amplifiers. With on-board equalization, high efficiency, and low current draw, they deliver clean, dynamic power without stressing the electrical system. Both amps mount to a durable powder-coated bracket for secure, long-term stability in rugged environments.
Installation is designed for simplicity: the package includes all required wiring harnesses for plug-and-play integration and a line output converter to interface seamlessly with the OEM base model audio. With only basic hand tools, you can achieve a complete, transformative sound upgrade without complicated modifications.
For Bronco owners seeking a dramatic leap in sound quality, output, and clarity, the MB Quart Stage 6 system delivers premium performance custom-built for your adventures.
