Upgrade your Can-Am Defender’s sound with the MB Quart MBQD-STG4A-1 Stage 4 Visor Audio System. Designed specifically for Defender models (2017–2025), this 320-watt system integrates into the vehicle’s front upper interior for a clean, factory-style fit. It delivers powerful, full-range audio while maintaining cabin space and durability for off-road use.

At the core of the system is an integrated visor enclosure housing four 6.5-inch coaxial two-way speakers with 0.75-inch titanium tweeters and a built-in NA2-320.4 four-channel amplifier. The system is powered through a compact, high-efficiency amp that provides balanced, distortion-free output for clear music playback in any environment.

The GMR-LED gauge-mount radio adds AM/FM, Bluetooth, USB, and AUX connectivity with Apple and Android device control. Pre-installed speakers, amplifier, and source unit simplify setup with plug-and-play harnesses and waterproof connectors, no custom fabrication required.

Built to handle harsh outdoor conditions, all components carry an IP67 rating for protection against dust, water, and vibration. The kit includes complete mounting hardware and wiring for an easy, vehicle-specific install. Backed by MB Quart’s engineering, the MBQD-STG4A-1 Stage 4 Visor Audio System delivers reliable, high-performance sound for every Defender adventure.
