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 installation. 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 instal-
lation work carried out by a specialist as verification of
correct installation and connection of the unit is a prere-
quisite for warranty cover of the HELIX amplifier.
Install your amplifier at a dry location where there is suf-
ficient air circulation to ensure adequate cooling of the
equipment. 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 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 compo-
nents, 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 ground. Any other system could cause dama-
ge 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 dan-
ger 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 cushio-
ned 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-quali-
ty connections and materials. Ask your dealer for high
quality accessories.
