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
• Four 8-gauge, self-tapping screws
• Power and speaker wiring harness
• Auxiliary-in, line-out, and subwoofer-out wiring harnesses
• NMEA 2000® drop cable
Tools Needed
• Phillips screwdriver
• Electric drill
• Drill bit (size varies based on surface material and screws
used)
When selecting a mounting location for the device, observe
these considerations.
• You must mount the device in a location where it is not
submerged.
• You must mount the device in a location with adequate
ventilation where it is not exposed to extreme temperatures.
• You should mount the device so the cables can be connected
easily.
• To achieve IPX2 water ingress protection, you must mount
the device on a vertical surface with the connectors pointing
downward.
• You can mount the device on a horizontal surface, but such
positioning might not achieve IPX2 water ingress protection.
• To avoid interference with a magnetic compass, you must
mount the device at least 15 cm (6 in.) away from a compass.
Mounting the Device
NOTICE
If you are mounting the device in fiberglass, when drilling the
pilot holes, use a countersink bit to drill a clearance counterbore
through only the top gel-coat layer. This will help to avoid
cracking in the gel-coat layer when the screws are tightened.
NOTE: Screws are included with the device, but they may not
be suitable for the mounting surface.
Before you mount the device, you must select a mounting
location, and determine what screws and other mounting
hardware are needed for the surface.
Place the device in the mounting location, and mark the
1
location of the pilot holes.
Drill a pilot hole for one corner of the device.
2
Loosely fasten the device to the mounting surface with one
3
corner, and examine the other three pilot-hole marks.
Mark new pilot-hole locations if necessary, and remove the
4
device from the mounting surface.
Drill the remaining pilot holes.
5
Secure the device to the mounting location.

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.

Mounting Considerations
CAUTION
In high ambient temperatures and after extended use, the
device enclosure may reach temperatures deemed dangerous
to touch. As a result, the unit must be installed in a location
where it cannot be touched during operation.
NOTICE
This device should be mounted in a location that is not exposed
to extreme temperatures or conditions. The temperature range
for this device is listed in the product specifications. Extended
exposure to temperatures exceeding the specified temperature
range, in storage or operating conditions, may cause device
failure. Extreme-temperature-induced damage and related
consequences are not covered by the warranty.

If you are installing the stereo on a boat with a metal
hull, you must use a ground-dependent antenna. If
you are installing the stereo on a boat with a nonmetal hull, you must use a ground-independent
antenna. See the installation instructions provided
with your antenna for more information.

Connecting to Power
When connecting the stereo to power, you must connect both
power wires. The yellow power wire must connect to the battery
to provide sufficient power to the stereo. The red ignition should
be connected through the ignition or another manual switch to
enable on/off control of the stereo. This installation method
provides the best performance because the yellow wire retains a
constant trickle-power draw that optimizes the startup time for
the stereo.
NOTE: If you will be storing the vessel for an extended period of
time, you should consider connecting the yellow wire through a
breaker or similar switch, so you can disconnect the tricklepower draw from the yellow wire and avoid draining the battery
during storage.
If you do not have the option of, or prefer not to use the ignition
to turn the stereo on and off, you can connect the red wire and
the yellow wire to the same switch on an electrical panel. This
installation method results in a slightly longer startup time for the
