CAUTION
Avoid routing power cables close to low-level input cables (LOW LEVEL INPUTS) and high-level input
cables (HI 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 FD 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
< 3 m
Cross sectional
> 4 mm
area in mm
2
AWG
< 11 AWG
Compliance with these wiring rules is essential for the safety of your electrical Installation and important for
maintaining maximum performance of your FD amplifier.
3.2 – Wiring the input and output signals on your FD amplifier
3.2.1 – Your head unit is equipped with RCA outputs
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.
3.2.2 – Your head unit is only equipped with amplified outputs (speaker driver outputs)
Route the wires from the head unit outputs and the speaker cables ensuring to insulate them from other high-power
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 FD 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.
