FUSION MS-RA70 Marine Stereos Head Unit
Important Safety Information
WARNING
- Failure to follow these warnings and cautions could result in personal injury, damage to the vessel, or poor product performance.
- See the Important Safety and Product Information guide in the product box for product warnings and other important information.
- This device must be installed according to these instructions.
- Disconnect the vessel’s power supply before beginning to install this product.
- Before applying power to this product, make sure it has been correctly grounded, following the instructions in the guide.
CAUTION
- To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling, cutting, or sanding.
NOTICE
- When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vessel.
- You must read all installation instructions before beginning the installation. If you experience difficulty during the installation, contact Fusion Product Support.
What’s In the Box
- DIN mounting plate
- Four 8-gauge, self-tapping screws
- Power and speaker wiring harness
- Auxiliary-in, line-out, and subwoofer-out wiring harness
Tools Needed
- Phillips screwdriver
- Electric drill
- Drill bit (size varies based on the surface material and screws used)
- Rotary cutting tool or jigsaw
- Silicone-based marine sealant (optional)
Mounting Considerations
-
The stereo can be mounted on a flat surface or in a single-DIN opening as a replacement for an existing stereo.
-
The stereo must be mounted in a location that allows open airflow around the rear of the stereo for heat ventilation.
-
If you are installing the stereo in a location that may be exposed to water, it must be mounted within 45 degrees of the horizontal plane.
- If you are installing the stereo in a location that may be exposed to water, the cable should have a drip loop to allow water to drip down off the cable and avoid damage to the stereo.
- If you need to mount the stereo outside a boat, it must be mounted in a location far above the waterline, where it is not submerged.
- If you need to mount the stereo outside a boat, it should be mounted in a location where it cannot be damaged by docks, pilings, or other pieces of equipment.
- To avoid interference with a magnetic compass, the stereo should be installed at least 15 cm (5.9 in.) away from a compass.
Mounting the Stereo in a New Location
NOTICE
- Be careful when cutting the hole to mount the stereo. There is only a small amount of clearance between the case and the mounting holes, and cutting the hole too large could compromise the stability of the stereo after it is mounted.
- Before you can mount the stereo in a new location on the mounting surface, you must select a location in accordance with the mounting considerations.
- Trim the template and make sure it fits at the mounting location.
- Adhere the template to the mounting surface.
- Using a drill bit appropriate for the mounting surface, drill a hole inside the corner of the dashed line on the template to prepare the mounting surface for cutting.
- Using a rotary-cutting tool, cut the mounting surface along the inside of the dashed line on the template.
- Place the stereo in the cutout to test the fit.
- If necessary, use a file and sandpaper to refine the size of the cutout.
- After the stereo fits correctly in the cutout, ensure the mounting holes on the stereo line up with the pilot holes on the template.
- If the mounting holes on the stereo do not line up, mark the new pilot-hole locations.
- Using an appropriately sized drill bit for the mounting surface and screw type, drill the pilot holes.
- Remove the template from the mounting surface.
- Make the necessary wiring connections (Connection Considerations, page 4).
- Place the mounting gasket on the back of the stereo (1).
- Place the stereo in the cutout.
- Secure the stereo to the mounting surface using the included screws (2).
- Snap the screw covers in place (3).
Replacing an Existing Stereo
-
Remove and disconnect the existing stereo.
-
If necessary, remove the existing wiring harness or install a vehicle- or vessel-specific wiring harness adapter (not included) to provide access to the power and speaker wiring.
-
Place the mounting gasket on the back of the stereo (1).
-
Place the mounting bracket (2) behind the mounting surface.
-
Make the necessary wiring connections (Connection Considerations, page 4).
-
Place the stereo in the opening.
-
Secure the stereo to the mounting bracket using the included screws (3).
NOTE: You might need to reach behind the mounting surface to hold the bracket in place when securing the stereo to the bracket. -
Snap the screw covers in place (4).
Connection Considerations
The stereo must be connected to power, to speakers, and to media input sources
to function correctly. You should carefully plan the layout of the stereo,
wired remote, speakers, optional NMEA 2000® network, and your input sources
before making any connections.
Port Identification
| Item | Description |
|---|
ANT
| Connects the stereo to a typical AM/FM antenna using an RF coaxial connector.
If you are installing the stereo on a boat with a metal hull, you must use a ground-dependent antenna, and if you are installing the stereo on a boat with a non-metal hull, you must use a ground-independent antenna. See the installation instructions provided with your antenna for more information.
ACC| Connects to a Fusion DAB module to receive DAB stations where
available (not included).
NMEA| Connects the stereo to an NMEA 2000 network (“N” models only) (
NMEA 2000 System Wiring Diagram , page 11).
USB| Connects the stereo to a USB source.
FUSE| Contains the fuse for the device.
See the device specifications for replacement fuse information.
1| Connects the stereo to the power and speaker wiring harness.
2| Connects the stereo to the auxiliary in and line/subwoofer out wiring
harness.
3| Reserved for future use.
Wiring Harness Wire and Connector Identification
Wire Function
| Wire Color/ Number|
Notes
---|---|---
Power (+)
| Red (yellow on some wire harnesses)| Connects to the positive terminal of a 12 Vdc power source capable of supplying 15 A.
Ground (-)
|
Black
| Connects to the negative terminal of a 12 Vdc power source capable of
supplying 15 A. This wire should be connected before connecting the red (or
yellow) wire. All accessories connected to the stereo must share a common
ground location.
Amplifier on| Blue| Connects to an optional external amplifier to turn it on
when the stereo turns on.
Mute
|
Brown
| Activates when connected to ground.
For example, when connected to a compatible hands-free mobile kit, the audio mutes or the input switches to AUX when a call is received and the kit connects this wire to the ground. This function quality can be configured from the settings menu.
Dim
|
Orange
| Connects to the boat’s illumination wire to dim the stereo screen when the lights are on.
The gauge of the illumination wire must be suitable for the fuse supplying the circuit it is connected to.

| Each cable provides a single mono output to a powered subwoofer or subwoofer amplifier, and one or both cables can be used, depending on the connection requirements of the subwoofer or amplifier.
A connected subwoofer is associated with the volume control for zone 1.
Connecting to Power
When connecting the stereo to power, you should connect it through the
ignition or another manual switch.
If it is necessary to extend the power and ground wires, use 14 AWG (2.08 mm?)
wire. For extensions longer than 1 m (3 ft.), use 12 AWG (3.31 mm-) wire.
-
Route the red power wire (1) to the ignition or another manual switch (2), and route the black ground wire (3) to the battery.
-
If necessary, route a wire (4) between the switch and the battery.
-
Route the wiring harness plug to the stereo.
Do not connect the wiring harness to the stereo until after all of the bare wire connections have been made. -
Connect the black wire to the negative (-) battery terminal.
-
Connect the red power wire to the ignition or another manual switch, and connect the switch to the positive (+) battery terminal if necessary.
-
Connect the wiring harness plug to the stereo.
Speaker Zones
- You can group speakers in one area into speaker zones. This enables you to control the audio level of the zones individually. For example, you could make the audio quieter in the cabin and louder on deck.
- You can set the balance, volume limit, subwoofer level, and name for each zone.
