Installation
Installation
It is recommended that a professional who is skilled in all
aspects of installation and operation install the MCC204
and any associated mobile audio equipment.
Amplifier Ventilation
Always provide adequate ventilation for the MCC204. The
amplifier requires an adequate airflow into the cooling fan,
which is located on the left side of the amplifier. The warm
air exits the amplifier through vents on the heatsinks. See
figure 1. Be sure to provide at least 1-1/2 inches clearance
in front of the cooling fan and 1 inch clearance at the sides
of the heatsinks.
The cooling fan is controlled by temperature sensors,
attached to the interior of the tunnel. The fan is normally
off. If the program material contains sustained loud pas-
sages demanding high power, the fan will turn-on to in-
crease cooling. If cooling is still not sufficient, additional
heating will shut down the amplifiers internal power sup-
ply completely and the Power Guard LEDs will light. The
fan will continue to run and once normal temperatures are
restored, operation will resume.
The amplifier can be mounted vertically or horizontally
and may be located under a seat if adequate clearance is
available. The preferred installation method is to mount the
amplifier directly to the vehicle frame using the hardware
supplied with the amplifier.
It is not recommended that the amplifier be mounted
under the hood or in a location where it will be directly ex-
posed to the elements. The openings in the fan housing and
heat tunnel vents can allow internal components to be dam-
aged by exposure to water, chemicals or any form of road
dust or debris.
Removing the Glass Panel
To access the MCC204 Controls, remove the glass panel
by removing the four hex bolts with the supplied 3/32 hex
key. See figure 2. Attach the supplied suction cup to the top
center of the glass panel and carefully raise it high enough
to put your hand under. Temporarily place the removed
glass panel in a safe place, remove the suction cup and
save it for future use.
Removing the End Caps
To access the MCC204 Connecting Terminal Blocks, re-
move the Glass Panel first (the above step) and then re-
move the Phillips Screws holding the End Caps on both
sides of the amplifier and lift the end caps off. See figure 3.
