INSTALLATION
16
The fuse/protection circuit breaker must
be installed within 30 cm of the battery.
Warning!
Installation Sequence:
Before installing the amplifier, disconnect the negative
pole from all the batteries in the system;
Secure the amplifier so that there is access to the con-
nectors;
Properly install, in the vehicle, the power cables, from
the battery to the busbar, fuse holders or circuit brea-
kers, use the cable with the appropriate section (see
Table 1). Make all connections to copper busbars (if
any), fuse holders or circuit breakers, but do not install
fuses or circuit breakers in the Off position;

Connect the power to the amplifier with the correct
polarity. Connect all positive (+) terminals that come
from the fuse holders or circuit breakers to the positive
connectors of the amplifier, and all negative (GND) ca-
bles from the negative busbars or terminals of the
batteries to the negative battery connector;
Install the signal input cables appropriately. The input
signal cables shall be installed away from the power
cables;
Connect the RCA cables to the main unit and ampli-
fiers. Connect the RCA cables to the main unit and
amplifiers;
Install the audio output cables to the appropriate section
(see Table 2) and away from the power and audio input
cables;
Connect the audio output cables to the amplifier and
speakers, respecting the positive (+) and negative (-)
polarities;
Install together with the power cables, the remote power
cable with 1.5 mm² section or larger;
Connect the remote power cable to amplifier REM

terminal and to a 12V source switch driven or remote
power output from the main unit;
After connecting the cables, before powering the
system, check if all connections are correct and if
there are no short-circuits between the cables and the
ground cables;
Reconnect the negative (GND) of the batteries;
Check if remote-driven switch is in the Off position, and
if the main unit is Off, then insert the fuses or drive the
circuit breakers.
To set the gain of your amplifier properly, follow the steps
below:
With the gain set to minimum, turn on the head unit and
the remote switch to power on the amplifier. Wait until
only the power LED is on;
Disconnect the output cables from the amplifier outputs;
Reproduce a 50Hz sine wave signal through the head
unit;
Set the volume of the head unit to about 70% of its
capacity;
Turn up the gain clockwise slowly until the "CLIP" LED
starts blinking;
Return the gain to the limit where the "CLIP" LED stops
blinking and remains Off.
Procedures for Setting the Gain
Some head units with higher tension RCA outputs, may
reach max power even with the gain set close to
minimum. In such cases, limit the volume of the head
unit in such a way the
