Important Installation Information
•
This appliance may only be connected to a 12 volt system with negative ground.
•
Because of high power unit, using the unit while the engine is stopped may totally discharge the
battery, please run the engine in using the unit.
•
The heat radiated when the amplifier is used means that sufficient air circulation is requered 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. Installation
in the boot is recommended.
•

dirt.
•
Make sure that the input/output cables are sufficiently distant from the power supply cables as
otherwise interference may occur.
•

Connection Power Supply
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
•
Amplifiers demands.
•
Make sure that the power lines to GND and to the +12 V terminal have been suffciciently specivied.
a cable cross- section of 12 mm² must be used to connect the battery to the amplifiers terminals.
•
First connect the amplifiers GND terminal to the batterys minus pole. It is very important that the
connection point. A loose connection may cause malfunctions or interference noise or distortion.
•
The +12V amplifier connection must then be connected with a power cable possessing an integrated
fuse to the batterys plus pole. The fuse should be located close to the battery.
•
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 0,75mm² is sufficient for connecting the amplifiers REMOTE Connection
and control device.
