WIRING
Make sure before any connection is made to the amplifier or source unit, ensure that you turn the
audio system off. Failure to do so could result in either the stock system or your new FUSION
product being damaged. FUSION does not warranty damaged amplifiers due to incorrect
installation.
When wiring the FUSION amplifier, ensure that the wires are away from sharp objects and that
rubber grommets and insulated bungs are used when wiring through door jams and any other
steel panels. FUSION recommends using 4 gauge power and ground wire for power installation.
Please see power cable calculator (Fig.1).
Ensure that when connecting the wires to the speakers and audio system, the terminals and
connections are protected from the vehicle chassis and each other. If the wires short together or
touch the vehicle chassis, the audio system could be damaged.

The above chart shows cable gauges to be used, if no less than a 0.5 volt drop is acceptable. If aluminium
wire or tinned wired is used, the gauges should be of an even larger size to compensate. Cable gauge size
calculation takes into account terminal connection resistance.
