General installation instructions for HELIX amplifiers
Before you start installation, disconnect the car battery at
the minus pole. We would urge you to have the installation
work carried out by a specialist as verification of correct
installation and connection of the unit is a prerequisite for
warranty cover of the HELIX amplifier.
Install your amplifier at a dry location where there is suffi-
cient air circulation to ensure adequate cooling of the equip-
ment. For safety reasons, the amplifier must be secured in a
professional manner. This is performed by means of four
fixing screws screwed into a mounting surface offering suf-
ficient retention and stability. Before drilling the holes for
the screws, carefully examine the area around the installati-
on position and make sure that there are no electrical cables
or components, hydraulic brake lines or any part of the
petrol tank located behind the mounting surface - otherwise
these could be damaged. You should be aware of the fact
that such components may also be concealed in the double-
skin trim panels/mouldings.
General instruction for connecting the amplifiers
The HELIX amplifiers may only be installed in motor vehicles
which have a 12-volt minus pole connected to the chassis gro-
und. Any other system could cause damage to the amplifier
and the electrical system of the vehicle.
The plus cable from the battery for the complete system
should be provided with a main fuse at a distance of max.
30 cm from the battery. The value of the fuse is calculated
from the maximum total current input of the car audio
system. Install the cabling in a manner which precludes any
danger of the leads being exposed to shear, crushing or
rupture forces. If there are sharp edges in the vicinity (e.g.
holes in the bodywork) all cables must be cushioned and
protected to prevent fraying.
Never lay the power supply cables adjacent to leads and
lines connecting other vehicle equipment (fan motors, fire
detection modules, gas lines etc.).
In order to ensure safe installation, use only high-quality
connections and materials. Ask your dealer for HELIX
accessories.
