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 8-gauge, self-tapping screws
• Two screw covers
• Power and speaker wiring harness
• Auxiliary-in, line-out, and subwoofer-out wiring harnesses
• 2 m (6 ft.) NMEA 2000® drop cable
• Dust cover
Tools Needed
• Phillips screwdriver
• Electric drill
• Drill bit (size varies based on surface material and screws
used)
• Rotary cutting tool or jigsaw
• Silicone-based 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
below or 15 degrees above the horizontal plane.
• If you are installing the stereo in a location that may be
exposed to water, you should install any connected cables
with 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 À to test the fit.

DRAFT
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 (Connection
Considerations,
page 2).
12
Select an option:
• If you are installing the stereo in a dry location, place the
included mounting gasket Á on the back of the stereo.
• If you are installing the stereo in a location that is exposed
to water, apply silicone-based marine sealant on the
mounting surface around the cutout.
NOTICE
Do not install the included mounting gasket if you applied
sealant to the mounting surface. Using sealant and the
mounting gasket may reduce water resistance.
13
Place the stereo into the cutout.
14
Secure the stereo to the mounting surface using the included
screws Â.
You should hand-tighten the screws when securing the
stereo to the mounting surface to avoid overtightening them.
15
Snap the screw covers in place Ã.
Connection Considerations
For the stereo to function correctly, you must connect it to
power, to speakers, and to input sources. You should carefully
plan the layout of the stereo, speakers, input sources, optional
NMEA 2000
network, and optional
FUSION PartyBus™ devices
or network before making any connections.

Power (+) Yellow Connects to the positive terminal of a
12 Vdc power source capable of
supplying 15 A.
Ignition Red Connects to a separately-switched,
12 Vdc connection, such as an
ignition bus, to turn the stereo on
and off. If you are not using a
switched 12 Vdc connection, you
must connect this to the same
source as the yellow (power) wire

Connecting to Power
When connecting the stereo to power, you must connect both
power wires. You should connect the yellow power wire directly
to the battery. This provides power to the stereo and a constant
trickle-power standby feed.
You should connect the red signal wire 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 through the ignition
or another manual switch, you can connect the red wire to the
yellow wire, and connect them both to the positive (+) battery
terminal.
You must connect the power wire to the battery through a 15 A
fuse or a 15 A circuit breaker.
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 wire, use 22 AWG (0.33 mm2) wire.
1
Route the yellow power À, red signal Á, and black ground
Â
wires to the 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
Complete an action:
• If you are routing the red wire through the ignition or
another manual switch Ã, connect the red signal wire to
the ignition or switch, install a 15 A fuse Ä on the yellow
wire as close to the battery as possible, and connect the
yellow wire to the positive (+) battery terminal.
• If you are not routing the red wire through the ignition or
switch, connect the red wire to the yellow wire, install a
15 A fuse as close to the battery as possible, and connect
both wires to the positive (+) battery terminal.
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.
Up to two pairs of speakers can be connected per channel of
each zone, in parallel. A zone can support no more than four
speakers using the on-board amplifier.
Zones 1 and 2 are powered by the on-board amplifier. To use
the RCA line outputs and the RCA subwoofer outputs for zones
1 and 2, you must connect external amplifiers.
Zones 3 and 4 are available as line-level outputs only. To use
the RCA line outputs and the RCA subwoofer outputs for zones
3 and 4, you must connect external amplifiers.
You can set the balance, volume limit, tone, subwoofer level,
subwoofer frequency, and name for each zone.
