Hertz HMR 18 Marine Source Unit with Bluetooth 5.0 (HMR18)
Hertz HMR 18 Marine Source Unit with Dual-Zone Control and Bluetooth 5.0 (HMR18)
The Hertz HMR 18 marine source unit brings advanced technology and seamless connectivity to your onboard audio. It gives you control over two independent zones with dedicated subwoofer outputs, so different areas of the boat can match each guest’s listening preferences.
Dual-zone audio control for tailored sound across your boat
Two independent zones let listeners enjoy the right balance in separate areas, which helps you manage volume and tone for different spaces without forcing one “one-size-fits-all” mix. Each zone also includes its own line output, so zone-based system layouts stay straightforward.
- Two independent audio zones
- Dedicated subwoofer output per zone
- 2x L+R line outs (one per zone)
- Subwoofer out (RCA) 1x L+R with LPF: 80, 120, 160 Hz
Wireless streaming and practical onboard sources
Bluetooth® 5.0 audio streaming makes it easy to play music from a smartphone or compatible device, therefore keeping listening simple without a cable. The Hertz HMR 18 also includes AM/FM tuner support and an AUX input for additional source flexibility.
- Bluetooth 5.0 audio streaming
- AM/FM tuner (EU/US)
- AUX input (RCA) 1x L+R

Front-panel protection for marine conditions
An IP66-rated front panel supports confident use on the water. It also adds UV resistance and salt fog operability for season-after-season operation.
- Front panel IP rating: IP66
- UV resistance (ASTM-D4329)
- Salt fog operability (ASTM-B117)
Simple on-unit control and clear display
A 2.8-inch DOT Matrix display keeps key information easy to view while you manage your system. Three EQ presets plus bass/treble EQ help you shape the sound quickly for different listening situations.

- Bass-treble EQ
- 3 EQ presets
Optional wired remote for added control on board
The optional HMC U1 remote control adds another way to manage playback and volume around the boat with the Hertz HMR 18, and it supports installation in more locations thanks to its IPX7 certification. You can connect up to three remotes for control from multiple positions.
- HMC U1 optional remote control (sold separately)
