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. 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 chas-
sis ground of the vehicle, this may cause ground loops
resulting in loud hum noise.
3.2 MINIMUM IMPEDANCE LOAD
The output stages of the RODEK RI-450-200 multi channel am-
plifier are designed to give you high output power into 4 or 2
ohms loads in normal stereo configurations. In bridged mode,
the minimum impedance load is 4 ohms for the channels CH1/
CH2 and CH3/CH4. The amplifier might suffer from thermal
shut-down or even damage, if these recommended minimum
impedance load ratings are not considered appropriately.
3. MOUNTING OF THE AMPLIFIER
19
Before you attempt the installation of your RI-450-200 5-channel
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 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 securely
mounted, and special precautions must be taken to allow suf-
ficient cooling. The amp can get quite hot during operation, so
a clearance of at least 10cm 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-panel windows.
