Ø

Mount the amplifier in such a way you have access to the connectors;

Ø

The ground cable must be as short as possible and must be connected to the vehicle 
chassis and the battery negative;

Ø

Install  the  power  cables  in  the  vehicle  properly,  starting  from  the  battery  to  the  fuse 
holder or circuit breaker, use the cable with the appropriate size. Make all connections, 
install fuse holders or circuit breakers, but without placing the fuses or with the circuit 
breakers in the "Off" position.

Ø

Connect  the  power  cables  in  to  the  amplifier,  observing  the  polarity.  Connect  all  the 
positive cables from the fuse holder or circuit breaker to the positive conector of the 
amplifier and all the negative power cables from the batteries to the negative connector 
of the amplifier;

Ø

Install the signal input cables in a proper way, distant from the power cables;

Ø

Install the audio output cables with the appropriate section , distant from the power and 
audio input cables;

Ø

Connect the audio output cables to the amplifier and speakers respecting the positive 
(+) and negative (-) polarities;

Ø

Connect the RCA or the high signal input cables to the head unit and amplifiers;

Ø

Install the remote cable with the power cables, using 1.5mm² (15 AWG) cable or thicker;

Ø

;

Reconnect the ground of the batteries

Ø

Turn on the main unit and the amplifier will turn on the "On" LED indicating that it is in 
operation.

Ø

Connect  the  remote  power  cable  to  the  amplifier's  "REM"  terminal  at  the  main  unit's 
remote power output (when not using the high level signal inputs);

Ø

Before  powering  the  system,  verify  all  the  connections  and  make  sure  there  are  no 
mistakes or short-circuits on the power and ground cables;

Ø

Check if the headunit is turned off and then place the fuses in the fuse holders or switch 
the circuit breakers on;
