CONNECTIONS
GROUND CABLE
REMOTE TURN ON CABLE
RCA CABLES
• At least 8 gauge cable should be used for the ground connection to the amplifier.
• The amplifier ground should be connected directly to the chassis of the vehicle, to bare metal.
• The cable length should be kept to an absolute minimum.
• It is not recommended that you connect the ground cable to the vehicles seatbelts anchor point.
• A minimum of 18 gauge 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.
• Depending 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 running these cables from the source to the amplifier. Ensure that
they are placed away from all items that can generate any electrical interference, wiring 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 picking up interference.
