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 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.
