BOSS Marine Bluetooth Sound System – MGR350B + 4 × MR6B Black Speakers

Bring quality entertainment onto the water with the BOSS Marine Bluetooth Sound System, featuring the compact BOSS MGR350B round marine gauge receiver together with four black BOSS MR6B 6.5-inch marine speakers.

Designed specifically for marine environments, this system provides Bluetooth music streaming, USB and AUX connectivity, AM/FM radio and four-speaker audio while maintaining a clean, professional appearance at the helm.

The round gauge-style receiver is particularly well suited to aluminium boats because it requires significantly less dashboard space than a conventional rectangular stereo.

Bluetooth Music Streaming

Connect a compatible smartphone wirelessly via Bluetooth and enjoy music directly through the boat's sound system.

This makes it easy to play music without requiring CDs or additional media equipment.

Designed for Marine Use

Unlike a conventional automotive radio and speaker system, the BOSS MGR350B and MR6B speakers are designed specifically for marine applications.

The MGR350B receiver carries an IPX6 rating, providing protection against powerful water splashes and making it suitable for installation in exposed boat environments.

Compact Round Gauge Installation

One of the biggest advantages of the MGR350B is its compact round gauge-style installation.

The receiver uses an approximately 3-inch / 76mm mounting opening, allowing it to fit neatly into an aluminium console alongside other marine instrumentation.

This provides a clean, modern helm without requiring a large rectangular stereo opening.

Perfect for AluBoats

The BOSS Marine Sound System is an excellent optional upgrade for AluBoats recreational and fishing boats.

Four strategically positioned speakers provide audio throughout the boat while the compact receiver keeps the console clean and uncluttered.
