. mOUNTING Of THE AmPLIfIER

Before you attempt the installation of your RODEK amplifier,
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 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 instal-
lations, 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 securely
mounted, and special precautions must be taken to allow suf-
ficient cooling. T he 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, the 2-/4-channel models feature 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. behind or
below the mounting surface that may be damaged by the dril-
ling of the holes for the amplifier mounting screws. T he 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.

3.2 MINIMUM IMPEDANCE LOAD

The output stages of the RODEK amplifiers are designed to give
you extraordinary output power into 4 or 2 ohms loads in normal
stereo configurations. In bridged mode, the minimum impe-
dance load is 4 ohms. T he amplifier might suffer from thermal
shut-down or even damage, if these recommended minimum
impedance load ratings are not considered appropriately. T he
R1900N is stable into 1 ohm.
