3. Wiring
Warning
!
If you have any doubts about your ability to install the amplifier and wire the system properly, get it done by a Focal
distributor/installer.
Beware
!
Avoid routing power supply cables close to low-level input cables and high-level inputs, aerials, sensitive equipment
and bundled lines. High-current power supply cables can cause interference with audio signals
Beware
!
Keep cables as short as possible to optimise the system's performance and to reduce signal loss.
Beware
!
Before starting the connection phase, make sure the negative terminal (-) of the vehicle battery is disconnected (fig.1).
3.1. What power supply cable gauge should I use?
The DSA 500 RT needs a 30-amp power supply cable.
The power supply cable gauges to be used depend on how far away the cable is from the battery; details are given
in the table below.

Compliance with the wiring instruction is essential for the safety of your electrical installation; it is also important for
ensuring that you continue to get the best performance from your DSA 500 RT.
3.2. Wiring of the DSA 500 RT input and output signals
3.2.1. Your car radio is equipped with RCA outputs
Route all the modulation cables (RCA), speaker cables, the REMOTE cable and the REMOTE CONTROL cable by
isolating them from the other high powered accessories, and in particular electric motors (windscreen wipers, etc.).
Do not shorten the cables; they will be adjusted later.
3.2.2. Your car radio is only equipped with amplifier outputs (speaker outputs)
Rout all the modulation cables from the car radio outputs, speaker cables and the REMOTE CONTROL cable by
isolating them from the other high-power car accessories, in particular electric motors (windscreen wipers, etc.). Do
not shorten the cables; they will be adjusted later.
It is therefore not essential to wire the REM input, the DSA 500 RT being equipped with a signal detection system on
the high-level inputs.
