CAUTION
Avoid routing power cables close to low-level input cables (LOW LEVEL INPUTS), close to the car aerial
or sensitive equipment and harnesses. High-current power cables can cause interference that affects
audio signal.
CAUTION
Keep the cables as short as possible to maximise the quality of the installation. This will also limit signal
loss.
CAUTION
Before beginning the connection phase, remove the negative (-) terminal of the battery of the vehicle.

3.1 - What wire gauge should I use for the power cable?
Your FDS amplifier requires a power supply of adequate amperage.
The required wire gauge of power cables depends on the length of wiring to the battery. See recommended wire
gauge in the table below:
Length of cable to the battery in metres
Length < 3 m < 4 m < 5 m < 6 m < 7 m
Cross sectional
area in mm
2
> 4 mm
2
> 5 mm
2
> 5 mm
2
> 5 mm
2
> 5 mm
2
AWG < 11 AWG < 10 AWG < 10 AWG < 10 AWG < 10 AWG
Compliance with these wiring rules is essential for the safety of your electrical Installation and important for
maintaining maximum performance of your FDS amplifier.
3.2 – Wiring the input and output signals on your FDS amplifier
Route the RCA low-level wires, the speaker cables and the REM cable ensuring to insulate them from other powerful
automobile accessories, particularly electric motors (windshield wiper…). Keep the whole length of the cables, which
will be adjusted later on.
3.3 – Wiring the power supply to your FDS amplifier
3.3.1 – Route the positive power cable (+) making sure when doing so to route the cable to the opposite side of the
cables that you have previously installed – this is to avoid any interference. DO NOT CONNECT THE CABLE
YET.
