You should only use a voltmeter or a diode test la mp for checking the voltage
applying at car cables, because normal test lamps consume too high currents and
thus can damage the electronic system of the car.
When installing cables make sure that the connection cables are not squeezed or
damaged by sharp edges. Use rubber bushings for passing points.
In order to reduce parasitic induction of the generator or of other electric systems
of the vehicle, the amplifier should be directly powered by the car battery. It is not
allowed to supply other electric loads, such as the cooling fan, the windscreen
washer etc., via the same cable as the amplifier.
Use connection cables with a possibly large cross-section for connecting the power
supply and the ground of the amplifier. The necessary cross-section of the cable
depends on the power requirements of the components connected.
A cross-section of the cables that is too small can cause a cable to char through in
the worst case. Moreover, the increased ohmic resistance leads to unnecessary
power losses.
An additional fuse in the positive connection of the amplifier is necessary in any
case (fuse holder is not included in the scope of delivery). The fuse should be
installed close to the battery. In case of short circuit (e.g. if the connection cable is
worn through) the fuse disconnects the positive lead and thus avoids a damage of
the battery and prevents the supply cable from burning.
The strength of the fuse depends on the power consumption of the connected
devices of the car hi-fi system.
