Boss Audio MGR350B Marine Stereo w/AM/FM/BT/USB

The Boss Audio MGR350B Marine Stereo with AM/FM/BT/USB delivers compact, multi-source audio connectivity for recreational and tactical watercraft operations. Designed for operators who require reliable entertainment and situational awareness during extended water-based missions, this digital media receiver fits standard single-DIN openings and provides flexibility across multiple input formats. Whether deployed on patrol boats, rescue craft, or command vessels, the MGR350B maintains audio clarity in high-vibration marine environments while remaining lightweight enough for weight-sensitive platforms.

The MGR350B integrates AM/FM radio reception with Bluetooth wireless streaming, USB audio compatibility, and rear auxiliary input terminals to accommodate diverse audio sources and mobile devices. The compact form factor—measuring 6 × 5 × 11 inches and weighing just 2 pounds—minimizes installation footprint while the durable marine-grade construction resists saltwater corrosion and moisture intrusion common in offshore environments. The fixed-face design eliminates protruding controls that could snag gear or compromise cockpit ergonomics, and the single-DIN chassis standard ensures universal compatibility with existing marine audio panel cutouts.

This unit suits law enforcement marine units, coast guard training vessels, search-and-rescue teams, and military watercraft requiring hands-free audio control and multi-protocol connectivity without sacrificing space or weight margins. Installation requires only standard DIN mounting hardware and basic dash panel modification—no fabrication or adapter plates necessary. The rear USB port supports charging and audio streaming simultaneously, while the auxiliary input accepts legacy audio equipment or tactical communication interface adapters, making the MGR350B a forward-compatible retrofit for modernizing aging marine audio systems.
