JL Audio Master Remote MMR-20-BE Weatherproof Marine Remote Controller
Total Audio Control, Right Where You Need It.
Tired of running back to the helm every time you want to skip a track or turn up the volume? The JL Audio MMR-20-BE is a rugged, round, non-display wired remote controller engineered to put full command of your MediaMaster® source unit at your fingertips—no matter where you are on the boat.
Whether mounted at the swim platform, the flybridge, the bow lounge, or the rear canopy of your 4WD setup, this ultra-compact controller gives you instant access to your music. With a tiny footprint and a simple, single-hole design, the MMR-20-BE slips easily into the tightest, most crowded dash spaces.
Hardwired Reliability — No Batteries, No Dropouts
While wireless remotes run out of juice or drop their Bluetooth connections just as the party gets started, the hardwired MMR-20-BE delivers unyielding reliability. It requires zero battery replacements and is immune to wireless signal interference from other marine electronics.
Key Features & Benefits
