3. MOUNTING

Before you attempt the installation of your RODEK amplifier,
it is recommended to map out the complete audio system in
your vehicle and the respective wiring required. Please note
that - because of possible interference problems with the exi-
sting car electrics and electronics - especially the routing of
the signal cables and the chassis ground connection will have
a profound impact on the performance of the overall system.
Secondly, the correct mounting 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 audio installations, we strongly recommend you to consult
your nearest authorized RODEK dealer/installer.

3.1 MOUNTING LOCATION

The mounting location should be carefully selected, preferably
in the trunk compartment of your car! In the interest of passive
driver and passenger safety, the amplifier must be secure-
ly mounted, and special precautions must be taken to allow
sufficient cooling. Any car amplifier 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.
Make sure there is no wiring harness, fuel tank etc. behind
or below the mounting surface that may be damaged by the
drilling of the holes for the amplifier mounting screws. The
above mentioned clearance of at least 5 cm to all sides of
the amplifier is not only for proper cooling, but also because
the crossover controls must remain accessible. The ampli-
fier must NOT be mounted directly to the chassis
ground of the vehicle, this may cause ground loops
resulting in a loud hum noise.

3.2 MINIMUM LOAD IMPEDANCE

The output stages of the RODEK amplifiers are designed to give
you high power output into 4 or 2 ohms loads in normal stereo
configurations. In bridged mode, the minimum impedance
load is 4 ohms.
The RN-460-200 is built to drive 4 or 2 ohms loads connected to
CH5 (subwoofer channel).
