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, brake lines or
electrical wiring.
3. Ensure the Amplier is securely fastened to
the vehicle 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.

5. Ensure the mounting location has sufcient
air ow around the amplier. If the amplier
is mounted in an enclosed space a 3” fan
with ducting should be used to aid in air
ow.
6. Do not mount any amplier on a subwoofer
enclosure as extended exposure to vibration
may cause malfunction of the amplier.
7. Ensure you use the recommended gauge
wire/cable for all amplier connections.
POWER
FUSION ampliers should be connected directly
to the +12V battery terminal with an inline fuse or
circuit breaker as close the battery as possible.
GROUND
When grounding/earthing your amplier ensure that
the location is a good source of ground (preferably
the oor pan). Make sure the metal is clean of paint
etc as a poor earth could damage your audio system.
REMOTE TURN ON
This connection turns the amplier 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. Either a power antenna wire or ACC +12V.
LOW LEVEL 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.
WIRING
1. Ensure the audio system is turned off before
making any connections to the amplier,
speakers or source unit, failure to do so could
result in permanent damage to the audio
system.
2. When wiring the FUSION amplier ensure
that the cable is protected from sharp objects
and always use rubber grommets when wiring
through metal panels.
3. Ensure all terminals and connections are
protected from the vehicle 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 amplier to the output level of you head unit. We recommend
the following method. NOTE: Remove screws and the top cover of amplier to access controls.
1. Turn the amplier level to zero
2. Turn the volume of the head unit to ¾ 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.
