IMPORTANT NOTES PRIOR TO INSTALLATION
- This device is only suited for a 12 volt system with negative ground.
- The radiated heat while operation requires sufficient air circulation at the place of installation. It is
very important that the heatsink fins do not have contact with any metal parts or any surfaces which
could impair air circulation. The amplifier may not be installed in small closed location or spaces
without air circulation (e.g. spare wheel recess or below the vehicle carpeting). We recommend the
installation in the vehicle’s trunk. Ensure sufficient protection against vibrations, dust and dirt.
- 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, particularly if you want to install several loudspeakers.
POWER SUPPLY AND TURN-ON-CONNECTION
INTERCONNECTION
ATTENTION: Before you start with the installation, disconnect the ground connection from the ve-
hicle’s battery in order to prevent short circuits.
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. A
cable cross section of at least 10 mm
2
must be used to connect the battery to the amplifier‘s terminals.
First connect the GND terminal 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 of the amplifier with the battery by using an appropriate cable including an
in-line fuse. This fuse should be located very close to the battery; for safety reasons not more than 30 cm
away. Only insert the fuse when the installation, including the connection of the loudspeakers, has been ac-
complished.
Then connect the remote turn-on-wire from the head unit with the amplifier‘s REM terminal. A cable with a
cross-section of 0.5 mm
2
is adequate.
LOUDSPEAKER CONNECTIONS
- The total impedance must not be lower than 2 ohms.
- Never connect loudspeaker cables with the ground of the chassis or the +12 V supply voltage.
If the amplifier is operated with a too low impedance or incorrectly used, the entire sound system
may be damaged. This means a warranty void in such cases.
