Marine audio amplifier for boats

The Poly-Planar ME70BT is an IPX6-rated 4-channel marine amplifier that delivers 45 watts per channel. It includes a remote display keypad with a backlit three-line screen and adjustable illumination. A built-in USB music player and AUX input provide wired and wireless source options. The unit also offers phone or Android charging and carries NMEA 2000 certification.

Suited for open-cockpit vessels needing wireless

This amplifier suits boat owners who want a water-resistant stereo with 100 metre Bluetooth range for streaming from a handheld device. The multiple EQ presets let you tune output for different zones. Buyers who need more than four channels or higher per-channel power should look at a different amplifier. Installations requiring a specific network protocol not listed here will not be supported.

Check power and mounting before purchase

Verify that the vessel’s electrical system can supply the amplifier’s operating voltage and current draw. Confirm there is a dry, accessible location for the remote keypad and that the display’s illumination level matches helm lighting conditions. Ensure the Bluetooth range meets the distance between the helm and typical listener positions. Check that the NMEA 2000 backbone uses compatible connectors for integration.
