3. IMPORTANT INSTALLATION INFORMATION
· This appliance may only be connected to a 12 volt system with negative ground.
· The heat radiated when the amplifier is used means that sufficient air circulation is required at the
place of installation. It is very important that the cooler’s cooler ribs do not contact any metal plating
or any surfaces which could impair air circulation. The amplifier may not be installed in small confined
spaces or spaces without air circulation (e.g. spare wheel recess or under the vehicle carpeting).
Installation in the boot is recommended.
· Install the amplifier in such a way that it is protected as far as possible against vibrations and dust
and dirt.
· Make sure that the input/output cables are sufficiently distant from the power supply cables as
otherwise interference may occur.
· Make sure that the fuse and operating elements are accessible after installation.
· The appliance’s reliability and performance depend on the quality of installation. Preferably get an
expert to install the system, particularly if you want to install several loudspeakers or a complex multi-
way system.
4. CONNECTIONS
4.1 POWER SUPPLY AND AUTOMATIC SWITCHING ON
Important notice: Before commencing the installation, disconnect the plus terminals from the car
battery in order to prevent short circuits.
The power cabling usually installed in on-board car networks is not sufficient for a power amplifier’s
demands. Make sure that the power lines to GND and to the +12 V terminal have been sufficiently
specified. A cable cross-section of at least 10 mm² must be used to connect the battery to the amplifier’s
terminals.
First connect the amplifiers GND terminal to the battery’s minus pole. It is very important that the
connection is good. Dirt residues must be carefully removed from the battery’s connection point. A loose
connection may cause malfunctions or interference noise or distortion.
The +12 V amplifier connection must then be connected with a power cable possessing an integrated
fuse to the battery’s plus pole. The fuse must be located close to the battery, the length of cable from the
battery’s positive pole to the fuse must be less than 60 centimetres for safety reasons. Only insert the
fuse when all installation work, including the connection of the loudspeakers, has been completed.
