Fusion Wire Harness Zone 1 & 2

This Fusion wire harness connects Zone 1 and Zone 2 audio outputs on compatible marine stereos. It uses a B Port-RCA interface for signal transfer. The harness is designed for installation with MS-RA670 and MS-RA770 network media players. It provides the necessary wiring link for multi-zone audio setups.

B Port-RCA Interface Compatibility

The single specification that determines fit is the B Port-RCA connection type required by the stereo. This harness matches that exact interface for the MS-RA670 and MS-RA770 models. Using a different connector style will prevent proper installation. Verify your stereo model number before ordering.

Dual-Zone Audio Capacity

The harness comfortably handles stereo audio distribution to two separate zones simultaneously. It runs out when a third independent zone is required or when the source unit lacks the specific B Port-RCA output configuration. The wiring length supports typical console-to-amplifier runs in marine environments.

Questions about this item

How does the B Port-RCA harness connect Zone 1 and Zone 2 to the MS-RA670 or MS-RA770?

The harness plugs into the stereo's B Port and splits into RCA outputs for both Zone 1 and Zone 2, carrying line-level audio to external amplifiers in each zone.

What connector standard does the B Port use and what signal type does it carry?

The B Port uses a proprietary Fusion multi-pin connector that carries pre-amplified stereo audio and control signals for the two independent zones.

What physical space and mounting does this harness require behind the stereo?

The harness needs clearance for the B Port plug and two RCA cable runs; it has no brackets and simply routes behind the MS-RA670 or MS-RA770 head unit.
