Wiring Notes – General

Safety is crucial during these installations. Firstly, please ensure that you protect every
current carrying cable with an appropriate fuse. Remember that if you use a capacitor or
supplementary battery you have the potential to be back feeding the main cable up the car
FROM the back so you will need to use a fuse a short distance from these storage devices
as WELL as a fuse at the front of the vehicle near the battery. Make absolutely certain that
the insulation of the cable is not pressed up against sharp edges or anything that could
gradually cut its way through. Always use cable grommets where wires pass through metal
or other perpendicular surfaces. Finally, ensure that your wiring is protected from coming
loose by using strain relief points on the cable. Please do not for one second dismiss the
possibility of a badly installed amplifier causing a fire. Do it properly. Barbecued cars and
owners are NOT covered under warranty ;-)
