General installation instructions for HELIX amplifiers
To find out how HELIX amplifiers work best for you, read
this manual carefully and follow the instructions for instal-
lation. We guarantee that this product has been checked
for proper functioning before shipping.
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
equipment. For safety reasons, the amplifier must be secu-
red in a professional manner. This is performed by means
of four fixing screws screwed into a mounting surface
offering sufficient retention and stability.
Before drilling the holes for the screws, carefully examine
the area around the installation position and make sure
that there are no electrical cables or components, hydrau-
lic brake lines or any part of the petrol tank located behind
the mounting surface - otherwise these could be dama-
ged. 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 vehi-
cles which have a 12 Volt minus pole connected to the
chassis ground. 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 body-
work) 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 con-
nections and materials. Ask your dealer for high quality acces-
sories.
