ground cable
• The ground cable needs to carry the same current as the power cable. At least an 8
gauge cable should be used.
• The ampli
fi
er 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 vehicle’s seatbelt anchor point.
Remote Turn On
• 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
fi
tted inline to enable the ampli
fi
er to be turned on and off. Remember that if
this switch is left on you will
fl
atten the car battery.
RCA Cables
• Depending on the model number of your ampli
fi
er 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 ampli
fi
er.
• Please take extra care when running these cables from the source to the ampli
fi
er. Ensure that they are
placed away from all items that can generate any interference, wiring harnesses etc.
• It is recommended that the RCA cables should be run on the opposite site of the car to the previously
installed power cables, if possible.
