JL Audio MM55-HR MediaMaster Bluetooth Marine Digital Media Source Unit with Built-in Amplifier (does not play CDs)
When you want serious sound for your boat or powersports rig but don’t want a bulky stereo head unit on the dash, the JL Audio MM55-HR is the perfect fit. This hideaway MediaMaster receiver is engineered for true marine-grade performance and incredible sound, all while keeping your helm super-clean.
Engineered for Seamless Control and Easy Installation
The JL Audio MM55-HR doesn’t come with a screen or knobs of its own — and that’s by design. It’s meant to disappear behind the dash or in a storage compartment. What’s really cool is that you can control it through a Garmin, Raymarine, Simrad, or Lowrance multifunction display using NMEA 2000®, or a dedicated JL Audio MMR-40 remote. That means less clutter up front, and more flexibility with your install.
Power-Packed Audio Output
Despite its compact size, this unit doesn’t skimp on power. The built-in 100-watt amplifier (25 watts RMS x 4 channels) pumps out clean sound directly to your speakers. Plus, there are nine channels of 4-volt RMS preamp outputs split into three independent audio zones — each with its own subwoofer output. So, if you want a different level of bass up front versus the stern or cabin, you’ve got full control.
Three Separate Audio Zones for Maximum Flexibility
Think of each zone as its own personal DJ booth. Adjust the volume of each one separately, set different tone controls (bass, mid, treble), and fine-tune subwoofer output per zone. Want all the speakers around the helm cranked up but keep the cabin more relaxed? No problem. You can also set max volume limits for each zone so nobody accidentally blasts your favorite playlist too loud.
Wireless and Wired Media Options Galore
With the JL Audio MM55-HR, you can play virtually anything. Stream your favorite tracks wirelessly over Bluetooth — using Qualcomm® aptX™ for top-notch sound. Connect a USB drive loaded with music or plug in an iPhone and take direct digital playback control. Need to go analog? Dual RCA auxiliary inputs make it easy to hook up other devices. Plus, there are global AM/FM radio tuners and even digital HD radio for North America or DAB+ for Europe.
Tough Enough for Marine Adventures
Saltwater spray, UV rays, bumpy waves — none of these scare the MM55-HR. Its IP67 water-resistant design is built to handle the toughest marine and powersports environments. Even optional wired and wireless remotes are built to endure, like the IP66-rated MMR-40 or IP68-rated MMR-25W wireless remote.
App and Remote Control Options
Pair the unit with the MM-Remote app to control everything from your phone or go for a wired or wireless JL Audio remote for dedicated control. Either way, adjusting audio on the fly is super simple — even while underway.
More Than Just a Stereo — It’s a Whole-System Hub
This unit supports independent feature sets for each zone. High- and low-pass filters can be individually tailored per zone, so you can set your speakers and subs exactly how you like. Want bass-heavy tunes at the bow and a crisp, vocal-forward setup in the cabin? Consider it handled.
Remote Controller and Interface Accessories (Each Sold Separately):
- MMR-40 network controller: full-function water-resistant (IP66-rated) controller with full-color LCD (NMEA 2000 network)

The JL Audio MM55-HR is all about making life on the water sound amazing without crowding your helm. Its hideaway design, robust power output, and total zone control mean you can truly customize the sound across your entire boat. It’s one of those upgrades that’s small in size but massive in impact.
