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 6 mm² (MPX 2000) /
10 mm² (MPX 2500) must be used to connect the battery to the amplifier's terminals.
First connect the amplifier's 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.
Now connect the car hi-fi receiver's remote control connection to the amplifier's REM
control jack. A cable with a cross-section of 0.75 mm² is sufficient for connecting the
amplifier's REMOTE connection and the control device.
