General installation instructions for HELIX
components
To prevent damage to the unit and possible injury,
read this manual carefully and follow all installation
instructions. This product has been checked for
proper function prior to shipping and is guaranteed
against manufacturing defects.
Before starting your installation, disconnect
the battery’s negative terminal to prevent
damage to the unit, fire and / or risk of injury.
For
a proper performance and to ensure full warranty
coverage, we strongly recommend to get this prod-
uct installed by an authorized HELIX dealer.
Install your HELIX M FOUR DSP in a dry location
with sufficient air circulation for proper cooling of
the equipment. The amplifier should be secured
to a solid mounting surface using proper mount-
ing hardware. Before mounting, carefully examine
the area around and behind the proposed instal-
lation location to insure that there are no electrical
cables or components, hydraulic brake lines or any
part of the fuel tank located behind the mounting
surface. Failure to do so may result in unpredictable
damage to these components and possible costly
repairs to the vehicle.
General instruction for connecting the HELIX
M FOUR DSP amplifier
The HELIX M FOUR DSP amplifier may only be in
-
stalled in vehicles which have a 12 Volts negative
terminal connected to the chassis ground. Any oth-
er system could cause damage to the amplifier and
the electrical system of the vehicle.
The positive 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 val-
ue of the fuse is calculated from the maximum total
current input of the car audio system.
Use only suitable cables with sufficient ca
-
ble cross-section for the connection of HELIX
M FOUR DSP. The fuses may only be replaced
by identically rated fuses (2 x 30 A) to avoid
damage of the amplifier.
Prior to installation, plan the wire routing to avoid
any possible damage to the wire harness. All
cabling should be protected against possible
crushing or pinching hazards. Also avoid routing
cables close to potential noise sources such as
electric motors, high power accessories and other
vehicle harnesses.
Congratulations!
