Fusion Apollo MS-WB670 Marine Hideaway Stereo


SKU: 010-02346-00 Category:


The Apollo WB670 marine hideaway stereo inherits key audio innovations and technological brilliance from Apollo RA670, reengineered in a compact, space-saving form factor designed to simplify dash space.  Save space at your console by controlling all of your zones using a compatible multifunction display (MFD), a Fusion remote, or a smart device.

How Does a Hideaway Stereo Work?

If the stereo is hidden away, how can it be controlled?  This is a great question.  There will be three main connections required for this stereo to work.  The first one, of course, is power.  This stereo requires a 12-volt power connection to give it juice.  The second will be the speaker wire output to your speakers.  Included in the box is a wiring harness to power two different zones, where the third zone will need an additional zone amplifier to power the speakers.  The final required connection will be either a NEMA 2000 cable or an ethernet cable to create a "network" of connected devices.



Airplay streaming

Airplay 2

This feature sends Hi-Fi audio quality to your speakers by using an onboard router, or by turning on the built-in WiFi access point.  You can now send different (or the same) audio to different zones in the boat.  Connect the WB670 Marine Hideaway Stereo via ethernet to a WiFi router and take control.  Completely compatible with VSSL amplifiers.

Fusion Garmin Display

Multi-Function Display (MFD)

The Apollo line connects to a Garmin multifunction display to control all of your entertainment using your boat's NEMA 2000 network.
