Connections
POWER SUPPLY AND REMOTE TURN-ON OF THE AMPLIFIER
NOTE: Do not connect the plus terminals to the car battery before other connections, or it may occur
short circuit.
The gauges of power cables should be enough for the power amplifier demands at least 5.27mm
2 .
The + 12V DC and ground cables should be at least 6 mm 2 .
Firstly connect the GROUND terminal to the battery negative pole. It is very important that the
connection is fastened. Loose connection may cause malfunctions or interference noise or distortion. Dirt
residues must be carefully removed from the battery connection point.
Then connect the +12V DC power terminal via an integrated fuse to the battery plus pole. The fuse must
be located close to the battery; the length of cable from the battery positive pole to the fuse must be
50cm for safety. Install the fuse after other connections including the connection of the stereo and the
loudspeakers. Finally connect the terminal of the remote turn-on to the amplifier REM control jack. The
cable gauge of 0.75mm
2 is sufficient for the amplifier REMOTE connection.
AUDIO CABLES
When installing the stereo input connection and the speaker connection, make sure the audio and the
power supply cables do not run the same side of the vehicle. This reduces crosstalk interference to the
audio cables.
LOUDSPEAKER CONNECTIONS
In normal operation mode (I.e. one loudspeaker on each Individual amplifier channel), the lowest
terminal Resistance is 2 Ohms per channel.
In bridge mode (two amplifier outputs combined), the lowest terminal resistance is 4 Ohms.
Never connect the loudspeaker negative terminals to the vehicle chassis.
Do not connect the +12V power supply to a loudspeaker output otherwise this will destroy the
amplifier terminals.
