Focal FP 1.800, FP 5.500

3 - Cabling

WARNING

If there is a doubt as to your ability to install the amplifier and to cable the system properly, get a

Focal distributor to do it for you.

WARNING

Before you begin the connection phase of set-up, remove the vehicle battery’s negative (-) terminal.

(fig. 1).

CAUTION

Avoid routing power supply cables close to low-level input cables (RCA), to your car’s radio aerial, or to

sensitive units. High-current power supply cables can cause static/interference that affects audio signals.

CAUTION

Keep cables as short as possible to optimise the system’s set-up performance and to reduce

signal loss.
