Connections
Ground Cable
●The round cable needs to carry the same current as the power cable. At least an 8 au e cable should be used.
●The amplifier round should be connected directly to the chassis of the vehicle, to bare metal.
●The cable len th should be kept to an absolute minimum.
●It is not recommended that you connect the round cable to the vehicles seatbelts anchor point.
Remote Turn n
●A minimum of 18 au e cable should be used for this connection.
●The cable should be run with exactly the same care and attention as the power cable and taken back to the source
(headunit) and joined to the remote cable provided.
●If the source (headunit) does not have a remote turn on cable then a 12v supply should be used. This will require a
switch to be fitted inline to enable the amplifier to be turned on and off. Remember that if this switch is left on you will
flatten the car battery.
RCA Cables
●Dependin on the model number of your amplifier and the number of speakers you wish to power you will have to run
either one or two RCA cables from the source to the amplifier.
●Please take extra care when runnin these cables from the source to the amplifier. Ensure that they are placed away
from all items that can enerate any interference, wirin harnesses etc.
●It is recommended that the RCA cables should be run on opposite sides of the car to the previously installed power
cables if possible, to avoid the cable pickin up interferance.
Power Cable
●At least an 8 au e cable should be used for both the power and the round connections to the amplifier.
●The power cable should be taken directly from the battery. Rubber rommets should be used when passin throu h
any bulkheads to prevent the cable from becomin chaffed or cut.
●It is vital that a fuse / circuit breaker (of at least equal value to the one fitted on the amplifier) is placed inline with the
power cable and is no further than ei hteen inches away from the battery.
●Please ensure that the fuse is not fitted until the entire installation procedure is complete.
●The two tables below are to help you decide on what cable is correct for you. The first enables you to select the size of
cable dependin on the len th required. The second will help you convert the cable size from American Wire Gau e to
Metric if you need to.
