MS-RA55 Installation Instructions
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
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.
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
• Mounting gasket
• Four 6-gauge, self-tapping screws
• Power and speaker wiring harness
• Two screw covers
Tools Needed
• Phillips screwdriver
• Electric drill
• Drill bit (size varies based on surface material and screws
used)
• Rotary cutting tool or jigsaw
• Marine sealant (optional)
Mounting Considerations
• The stereo must be mounted on a flat surface.
• 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
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.
Be careful when installing the stereo in an aluminum boat or a
boat with a conductive hull, if you require the electrical system to
be isolated from the boat hull.
Do not apply grease or lubricant to the screws when fastening
the stereo to the mounting surface. Grease or other lubricants
can cause damage to the stereo housing.
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.
1
Trim the template and make sure it fits at the mounting
location.
2
Adhere the template to the mounting surface.
3
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.
4
Using a rotary-cutting tool, cut the mounting surface along
the inside of the dashed line on the template.
5
Place the stereo in the cutout to test the fit.
6
If necessary, use a file and sandpaper to refine the size of
the cutout.
7
After the stereo fits correctly in the cutout, ensure the
mounting holes on the stereo line up with the pilot holes on
the template.
8
If the mounting holes on the stereo do not line up, mark the
new pilot-hole locations.
9
Using an appropriately sized drill bit for the mounting surface
and screw type, drill the pilot holes.
10
Remove the template from the mounting surface.
11
Make the necessary wiring connections (Connections,
page 2).
12
Place the mounting gasket on the back of the stereo

Connections
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, speakers, and your input sources
before making any connections.

Antenna
À
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.

a 12 Vdc power source capable of
supplying 10 A.
Ground (-) Black Connects to the negative terminal of

should be connected before
connecting the yellow wire. All
accessories connected to the stereo
must share a common ground
location.

Fuse
Ã
Contains the 10 A fuse.
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
2
) wire. For extensions longer than 1 m (3 ft.),
use 12 AWG (3.31 mm
2
) wire.
1
Route the power wire
À
to the ignition or another manual
switch
Á
, and route the black ground wire
Â
to the battery.
2
If necessary, route a wire
Ã
between the switch and the
battery .
3
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.
4
Connect the black wire to the negative (-) battery terminal.
5
Connect the power wire to the ignition or another manual
switch, and connect the switch to the positive (+) battery
terminal if necessary.
6
Connect the wiring harness plug to the stereo.

If the stereo is subject to strong electrical interference, this
interference might be heard through the speakers. You should
take appropriate action to suppress or reduce the noise.
• Add clip-on ferrite beads to the cables connected directly to
the product.
• Add clip-on ferrite beads to the device in the vessel that is
causing the interference.
• Disconnect the AUX input cable from the RCA connector
when it is not used.
