Marine and powersports headunit with 3-inch TFT

The DS18 MRX150 is a digital media receiver built for marine and powersports vehicles. It features a 3-inch colour TFT screen protected by Gorilla Glass with OCA full bonding. An IPx6 rating guards against powerful water jets, UV exposure and salt corrosion.

Two-zone audio control for separate listening areas

Two independent zones let you adjust volume and source independently for different areas of the craft. Four channels produce 50 watts each while 4-volt pre-outs feed external amplifiers without signal loss. Bluetooth provides wireless audio streaming and an AM/FM/WB tuner stores 37 presets across 18 FM, 12 AM and 7 weather-band channels.

IPx6 waterproof rating for open-cockpit

The IPx6 certification means the faceplate withstands heavy spray from any direction, a requirement for open-cockpit boats and exposed powersports mounts. Buyers who need a flush-mount chassis with a larger display or multi-zone DSP should consider other models.

Questions about this item

How do I wire the two-zone outputs on the MRX150 and what is the common mistake?

Connect four speaker wires to the 4 x 50 W channels and assign zones in the menu; the common mistake is leaving the second zone unassigned so it stays muted.

What maintenance does the IPx6-rated front panel need over time?

Rinse the Gorilla Glass screen with fresh water after salt exposure and check the USB port seal; the OCA bonding and UV-resistant coating require no reapplication.

At what point does the built-in voltmeter warn me during a long day on the water?

The on-screen voltmeter shows real-time battery voltage; watch for a drop below 12 V, which signals the electrical system can no longer sustain the 50 W per channel output.
