ØInstall the power cables in the vehicle/vessel 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;
ØConnect 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;
ØThe ground cable must be as short as possible and must be connected to the negative
connector of battery or vehicle chassis in case of metallic chassis;
ØInstall the signal input cables in a proper way, distant from the power cables;
ØConnect the RCA cables to the head unit and amplifiers;
ØInstall the audio output cables with the appropriate section, distant from the power and
audio input cables;
ØConnect the audio output cables to the amplifier and speakers respecting the positive (+)
and negative (-) polarities;
ØInstall the remote cable with the power cables, using 1.5mm² (15 AWG) cable or thicker;
ØConnect the remote power cable to the amplifier's "REM" terminal at the main unit's remote
power output;
ØBefore powering the system, verify all the connections and make sure there are no
mistakes or short-circuits on the power and ground cables;
Ø;Reconnect the ground of the batteries
ØCheck if the head unit is turned off and then place the fuses in the fuse holders or switch the
circuit breakers on;
ØTurn on the main unit and the amplifier will turn on the "POWER ON" LED indicating that it is
in operation.

ØMedia with sine wave test tone 60Hz
recorded at 0db;
ØScrewdriver 1/8" ( for gain setting).
Set up procedure:
This procedure is the same for both
Ø
gain controls;
ØTurn the gain control all the way down;
ØDisconnect the output cables from the
amplifier outputs;
ØTurn off all processing (bass, treble,
loudness, EQ, etc.);
ØSet the audio player volume to 3/4 of
full volume;
ØSet the audio player fader control to
center position (left and right fader
controls);
ØSet the crossover selector switch in "F";
Ø Use a 60 Hz sine wave;
ØConnect the AC voltmeter to the
speaker output connectors of the
amplifier. Make sure you test the
voltage at the correct connectors
(+ and –);
ØIncrease the gain control until the
target voltage is observed with the
voltmeter (see the chart below);
ØOnce you have adjusted the amplifier
to the correct voltage output, turn off
the source unit and reconnect the
speaker(s).

BATTERY CONNECTION DIAGRAM
When necessary the association of one or more battery banks to supply the
necessary current to the amplifier, it is recommended to use batteries of the same
brand, model, and if possible the same manufacturing lot so that the system has
the maximum performance.
For an ideal energy performance, we recommend that all batteries be connected to
positive and negative busbars and the busbars connected to the amplifier, as
shown in the diagram below:

1
Battery connections without the use of a busbar,
as shown in the example below, must be avoided.
This setting decreases the efficiency of supplying
power to the system.
All cables, positive and negative,
connected from the battery to the
busbar must be the same length.
Likewise the cables connected from
the busbar to the amplifier.
