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 Amplifier is securely fastened to the vehicle to prevent damage 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 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 vehicle chassis and from each other as failure to do so
could result in permanent damage to the audio system.
Power
FUSION amplifiers should be connected directly to the +12v battery terminal with an inline fuse or circuit breaker as
close to the battery as possible.
Ground
When grounding/earthing your amplifier ensure that the location is a good source of ground (preferably the floor
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 amplifier on and 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 interconnects and run them to the RCA outputs of the source/head unit, avoiding
running beside other looms and or power cable.
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.
Turn the amplifier level to zero
Turn the volume of the head unit to ¾ and the bass and treble to zero
Adjust the level control until the desired maximum volume is achieved without distortion.
Failure to follow these steps may cause permanent damage to the audio system.
