IMPORTANT NOTES PRIOR TO INSTALLATION
• This device is only suited for a 12 volt system with negative ground.
• Ensure that the input and output cables are sufficiently separated from the power supply cables. Otherwise
interferences may occur.
• Ensure the accessibility of the fuse and the operating elements after installation.
• The reliability and performance of the amplifier depends on the quality of installation. Preferably consult an
expert to install the system.
• Avoid any damage or removing of the components of the vehicle like wires, cables, board computer, seat
belts, gas tank or the like.
POWER SUPPLY AND TURN-ON-CONNECTION
ATTENTION: Before you start with the installation, disconnect the ground connection from the ve-
hicle's battery in order to prevent short circuits. Use the enclosed cable plug to connect each terminal.
The power wiring which is usually installed in on-board car networks is not sufficient for a power amplifier's
demands. Make sure that the power wires to GND and to the +12 V terminal has been sufficiently specified.
First connect the GND terminal [ 1 ] of the amplifier to an appropriate ground connection at the chassis. To
ensure a good connection, residue dirt and dust from the connection point. A loose connection may cause
malfunctions or interferences noise and distortion.
Then connect the +12 V terminal [ 2 ] of the amplifier with the battery by using an appropriate cable including
an in-line fuse. This fuse [ 4 ] should be located very close to the battery [ 3 ]; for safety reasons not more than
30 cm away. Only insert the fuse when the installation, including the connection of the loudspeakers, has been
accomplished.
Then connect the remote turn-on-wire [ 5 ] from the head unit with the amplifier's REM terminal. A cable with a
cross-section of 0.5 mm
