3 - Cabling your FPX amplifier
WARNING
Do not run the power cables near the low level inputs, high level inputs, antenna or sensitive equipment or
cabling. The power cables carry a high current, capable of interfering with the audio signal.
WARNING
Use the shortest possible cable lengths to optimise the quality of the installation and limit signal losses.
WARNING
Before beginning the connection phase, remove the negative (-) terminal from the battery of the vehicle
(fig.1).
3.1 Choosing cable of the correct gauge
Your FPX amplifier requires a power supply of the correct amperage.
The cable gauge to be used depends on the distance of the cable from the battery, as recommended in the following table:
Amplifier
FPX 4.800 and
FPX 2.750
FPX 1.1000
FPX 4.400 SQ
FPX 5.1200
It is essential to scrupulously adhere to the recommendations in this table for the safety of your electrical system; it
is also important to maintain the maximum performance of your FPX amplifier.
3.2 - Cabling your FPX amplifier's input signals
Route all the modulation cables (RCA), speaker cables, and the REM cable together, isolating them from other high-
power consumption equipment in the vehicle and, in particular, electrical motors (e.g. windscreen wiper motor, etc.)
Do not cut any cables down yet. You will do this later.
3.3 – Wiring your FPX amplifier's power supply
3.3.1 – Route the positive (+) power cable, taking care to keep it away from the cables you have already positioned,
to avoid any interference. DO NOT CONNECT THE CABLE YET.
