2. MOUNTING OF THE AMPLIFIER
ged by the drilling of the holes for the amplifier mounting
screws. The above mentioned clearance of at least 5cm to all
sides of the amplifier is not only for proper cooling, but also
because the crossover controls must remain accessible. The
amplifier must NOT be mounted directly to the chassis
ground of the vehicle, this may cause to ground loops with
loud hum noise.
3. ELECTRICAL WIRING
IMPORTANT! Disconnect the positive battery ter-
minal (+12V) or remove the main fuse near the car
battery before you start any wiring work!
The power supply of the car audio system must be
dis-connected until the entire wiring installation is
completed.
The recommended minimum power cable cross-sec-
tion of the main power supply cable is 20mm
2
, but if
you drive the amp hard, or you have multi amplifier
setup, a 35mm
2
power cable is needed.
Using main power cables with smaller cross sections
potentially result in unnecessary over-heating of the
amplifier circuitry, distortion at high volume levels
and may also cause the thermal protection circuitry
to shut-off the amplifier(s).
Use rubber grommets when running cables through any me-
tal or sharp plastic panels, to prevent accidental shorting or
shearing. Make sure the cables do not interfere with normal
operation of the vehicle.
Before you attempt the installation of your RODEK am-
plifier, it is recommended to map out the complete audio
system and the respective wiring required. Please note
that - because of possible interference problems with
the existing car electrics and electronics - especially the
routing of the signal cables and the chassis ground
connection will have a profound impact on the perfor-
mance of the overall system. Secondly, the correct moun-
ting location needs your attention too (proper cooling
of the amp!). Use only quality installation material and if
you have only little or no experience with complex car au-
dio installations, we strongly recommend you to consult
your nearest authorized RODEK dealer/installer.
2.1 MOUNTING LOCATION
The mounting location should be carefully selected, pre-
ferably in the trunk compartment of your car! In the inte-
rest of passive driver and passenger safety, the amplifier
must be securely mounted, and special precautions
must be taken to allow sufficient cooling. The amp can
get quite hot during operation, so a clearance of at least
5cm from both sides and from the top of the amp must
be considered.
Furthermore, this amplifier features an internal fan, so
the side panels must not be covered to allow for a good
air flow in and out of the side-panels windows.
Make sure there is no wiring harness, fuel tank etc. be-
hind or below the mounting surface that may be dama-
