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 installation work carried out by a specia-
list as verification of correct installation and
connection of the unit is a prerequisite for warran-
ty cover of the HELIX amplifier.
Install your amplifier at a dry location where there
is sufficient air circulation to ensure adequate coo-
ling of the equipment. For safety reasons, the
amplifier must be secured in a professional man-
ner. 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, hydraulic brake lines or any part of
the petrol tank located behind the mounting surfa-
ce - 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 ampli-
fiers
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 damage to the amplifier and the elec-
trical 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 high quality accessories.
