INSTALLATION GUIDELINES
1. Ensure the +12V lead is disconnected from the
battery before you connect any new equipment.
2. Ensure the mounting location will not interfere
with the gas tank or electrical wiring.
3. Ensure the Amplifier is securely fastened to the
vessel to prevent injury in the event of an accident.
4. Ensure all wiring is protected to avoid pinching
or crushing which could result in damage to the
audio system.
+12V CONNECTION
FUSION amplifiers should be connected directly to the
+12V battery terminal with an inline fuse or circuit
breaker as close the battery as possible.
GROUND CONNECTION
When grounding/earthing your amplifier ensure that the
location is a good source of ground. Make sure the metal
is clean of paint etc as a poor earth could damage your
audio system.
REMOTE TURN-ON CONNECTION
This connection turns the amplifier on & should be
connected to the remote turn on wire from the Head
Unit. If one is not available a switched 12v source must
be used.
RCA INPUTS
Choose the correct length RCA cable & run them to the
RCA outputs of the source/head unit, avoiding running
beside other looms & or power cable.
5. Ensure the mounting location has sufficient
air flow around the amplifier. If the amplifier is
mounted in an enclosed space a 3” fan with
ducting should be used to aid in air flow.
6. Do not mount any amplifier on a subwoofer
enclosure as extended exposure to vibration may
cause malfunction of the amplifier.
7. Ensure you use the recommended gauge wire/
cable for all amplifier connections.
WIRING
Ensure the audio system is turned off before making any
connections to the amplifier, speakers or source unit,
failure to do so could result in permanent damage to the
audio system.
When wiring the FUSION amplifier ensure that the cable
is protected from sharp objects and always use rubber
grommets when wiring through metal panels.
Ensure all terminals and connections are protected from
the vessel chassis and from each other as failure to do so
could result in permanent damage to the audio system.

LEVEL CONTROL
This control is used to match the input level of the amplifier to the output level of you head unit. We recommend the
following method. NOTE: Remove screws and the top cover of amplifier to access controls.
1. Turn the amplifier level to zero
2. Turn the volume of the head unit to and the bass
and treble to zero
3. Adjust the level control until the desired maximum
volume is achieved without distortion.
4. Failure to follow these steps may cause permanent
damage to the audio system.

Amplifier
Speakers
Check fuses and connections to battery
Check remote on connections to head unit
Replace fuse with correct type and amperage
Replace fuse with correct type and amperage
Move amplifier to vented area
Turn head unit down
Check that there are no speaker wires shorted to
other wires
Check RCA connection to head unit
Ensure you have set up the amplifier gain level control
Check head unit volume level
Check all power, remote on and ground connections
Check speakers for wire shorts
