Fusion Marine Audio — Stereos, Speakers & Amplifiers

One boat. The right system for every listening zone.

Shop Fusion marine stereos, speakers, subwoofers, amplifiers and installation accessories at MCOR. Start with your receiver and number of listening areas, then match the speakers, amplifier channels and wiring—not just the biggest peak-power number.

Compare Fusion stereos: choose the right starting point

Simple two-zone audio

Bluetooth, AM/FM and AUX in a compact stereo. A straightforward starting point when you do not need Fusion DSP or a networked Apollo system.

MS-RA60

Compact display plus DSP

Two zones, a color display, USB and Fusion DSP. NMEA 2000 connectivity supports compatible marine-network controls.

MS-RA210

Three zones, wired networking

Three-zone control and Fusion DSP with wired Ethernet networking. No built-in Wi-Fi; plan network equipment separately.

Apollo RA670

Four zones with Wi-Fi

Touchscreen control, built-in Wi-Fi and AirPlay 2. Four audio zones, with onboard amplification for two zones.

Apollo RA770

Newest touchscreen platform

4.3-inch touchscreen, Wi-Fi/AirPlay 2, USB-C and HDMI ARC. Four zones and Class-D onboard amplification; additional zones need external amplifiers.

Apollo RA800

Keep the receiver out of sight

A four-zone hideaway receiver with Fusion DSP. Plan a compatible remote or control interface and a protected mounting location.

Apollo WB675

Zones are not the same as amplified channels. A four-zone stereo does not automatically power speakers in all four areas. Check each model’s speaker outputs, pre-outs and external-amplifier requirements.

Need a smaller zone unit or an included wired control? Compare Apollo SRX400 and BB100. For a receiver-and-speaker bundle, see the RA210 / XS kit and check what is already included before adding accessories.

Match speakers, amplifiers and installation parts

Apollo amplifiers need Fusion DSP

Pair Apollo amplifiers with compatible Fusion DSP-enabled stereos. RA60, RA70 and BB100 are not substitutes for that requirement. Match RMS output, impedance and channel count to the speakers.

Compare DSP source units: RA210, RA670, RA770, RA800 and WB675. Check the individual amplifier’s system requirements.

Marine wiring is a separate purchase

Fusion speaker cable and RCA cable carry speaker-level or line-level audio; neither is a battery power kit. Use properly sized marine power/ground cable and battery-side fuse protection for the exact amplifier and cable run.

For Apollo full-size amplifier installations calling for 4-AWG cable, KICKER 47KMPK4 is a marine power-kit starting point—not a universal match. Confirm the required fuse, total cable length and amplifier manual before ordering.

Need help putting the complete system together? Contact MCOR with your boat, existing stereo model, speaker locations and the number of listening zones. We can help identify the right components without adding parts your kit already includes.
