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.

Mounting Considerations
• The stereo must be mounted in a location where there is
enough clearance for the open door of the stereo as
indicated on the template.
• The stereo must be mounted in a location that allows open
airflow around the rear of the stereo for heat ventilation.
• The stereo must be mounted within 45° of the horizontal
plane.
•
The cable should have a drip loop to allow water to drip down
off the cable and avoid damaging the stereo.
• If you want to mount the stereo outside the boat, it must be
mounted in a location well above the waterline, where it is not
submerged.
• If you want to mount the stereo outside the boat, it should be
mounted in a location where it will not be damaged by a
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 flush mount 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 mounting the stereo, you must choose a location
following the guidelines above.
Trim the template and make sure it fits in the selected
1
location.
Secure the template to the selected location.
2
Using a drill bit appropriate for the mounting surface, drill the
3
hole inside the corner of the dashed line on the template to
prepare the mounting surface for cutting.
Using a jigsaw or rotary tool, cut the mounting surface along
4
the inside of the dashed line indicated on the template.
If necessary, remove the sun cover from the stereo.
5
Place the stereo in the cutout to test the fit.
6
If necessary, use a file and sandpaper to refine the size of
7
the cutout.
After the stereo fits correctly in the cutout, ensure the
8
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
9
new pilot-hole locations.
Using an appropriately sized drill bit for the mounting surface
10
and screw type, drill the pilot holes.
Remove the template from the mounting surface.

Connect the wiring harnesses and wires, while observing
12
polarity.
Place the mounting gasket on the back of the stereo À.

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

Wire Identification
Connecting to Power
When connecting the stereo to power, you must connect both
power wires. The yellow power wire should be connected
directly to the battery, or connected using a 15 A isolator switch.
This provides power to the stereo and a constant trickle-power
standby feed. The red signal wire should be connected to the
same battery through the ignition or another manual switch to
turn the stereo on and off.
If you are not routing the red wire to the ignition or another
manual switch, you can connect the yellow to the red, and
connect them to the positive (+) battery terminal. You should put
a fuse on the red wire.
If it is necessary to extend the yellow power and black ground
wires, use 14 AWG (2.08 mm2) wire. For extensions longer than
1 m (3 ft.), use 12 AWG (3.31 mm²) wire.
If it is necessary to extend the red signal wire, use 22 AWG
(0.33 mm2) wire.
Route the yellow power À and black ground Á wires to the
1
battery and route the wiring-harness plug to the stereo.
Do not connect the wiring harness to the stereo until all of the
bare wire connections have been made.
2
Connect the black wire to the negative (-) battery terminal.

3
• Connect the yellow wire to the positive (+) battery
terminal, and route the red signal wire  to the ignition or
another manual switch Ã.
• Connect the yellow wire to the red, and connect them to
the positive (+) battery terminal.
Speaker Zones
You can group speakers in one area into speaker zones. You
can then control the audio level of the zones individually. For
example, you might want the audio quieter in the cabin and
louder on deck.
You can set the balance, volume limit, subwoofer level, and
name for each of the available zones. Up to two pairs of
speakers can be connected per zone in parallel to increase the
amplifier output.
Subwoofer Amplifier Connection Considerations
This stereo supports output to a powered subwoofer from all
zone outputs.
The subwoofer port on the stereo outputs a mono line-level
signal. The port output audio level is linked to the zone.
• You should connect the connectors to the included splitter.
• You need a splitter for each zone. One splitter is included.
Speaker Amplifier Connection Considerations
In addition to the two stereo speaker zones available through
the wiring harness, this stereo can be connected to multiple
amplifiers through zone connections.
• The blue wire from the wiring harness must be connected to
the amplifier to provide a signal to turn on the amplifier with
the stereo. If it is necessary to extend this blue signal wire,
use 22 AWG (0.33 mm²) wire.
• The audio output is a stereo line level output over standard
RCA cable.
Common Connections to the Stereo
You can connect a variety of additional media inputs and
outputs to the stereo, depending on the stereo model and the
devices to which you are connecting.
The connectors are color coded to assist you in making the
correct connections. For example, your TV may have an HDMI
connector. Connect the HDMI cable to the HDMI connector on
the stereo. This table lists some possible ways to connect
devices to the stereo.
NOTE: Not all connectors are available on all stereo models.

* Metal hull vessels should use a marine, AM/FM, grounddependant antenna. Other vessels can use a marine, AM/FM,

Audio Return Channel
The Audio Return Channel (ARC) enables you to play the audio
from the television over the stereo system speakers.
ARC eliminates the need to connect a separate audio cable
from the HDMI television to the stereo. Typically, in televisions
without ARC, to play the audio from the television over the
stereo system speakers, you would need a separate cable. With
ARC, the HDMI cable sends the television audio to the stereo.
The HDMI version 1.4 cables support ARC. When planning your
stereo installation, check whether your devices support ARC.
Most devices that support ARC have an ARC label on the HDMI
connector that supports ARC.
NOTE: The Fusion MS-AV750 supports ARC.
