⚡ Compact and Simple Gauge-Style Fit
The MGR350B uses a standard 3-inch gauge-style cutout, perfect for tight dash panels or helm consoles. Its clean look keeps your dash uncluttered while offering high-end functionality.
The backlit white-on-black LCD remains easy to read in direct sunlight or low light. Use the ergonomic rotary knob and sealed buttons to navigate playlists, adjust volume, and switch sources—even with wet fingers.
🔊 Power to Push Your System
Don’t let the size fool you—the MGR350B packs solid sound power. With 4 x 40 watts of built-in amplification, it drives up to four speakers without needing an external amp.
Want more volume or deeper bass? This unit includes RCA preamp outputs so you can easily connect a marine amplifier or subwoofer. Perfect for boaters who want to scale their system over time.

☀️ Boost System Longevity with Marine Window Tint
Boats absorb sun and heat all day. That constant exposure affects electronics like your stereo. Installing marine-grade window tint helps reduce glare, keep interiors cooler, and extend the life of equipment like the MGR350B.
We recommend Window Tint Delaware for expert tinting services. Their films are designed to hold up in marine environments with salt-safe adhesives and UV-blocking materials.
It’s a simple way to protect your investment while adding comfort and privacy to your vessel.
