OUNTING OCATION
The mounting location and position of your amplifier will have a great
effect on its ability to dissipate the heat generated during normal opera-
tion. The design of our cast aluminum heatsink serves to easily dissipate
the heat generated over a wide range of operating conditions. However,
to maximize the performance of your amplifier, care should be taken to
ensure adequate ventilation.

Trunk Mounting

Mounting the amplifier vertically on a surface with the fin grooves running
up and down will provide the best cooling of the amplifier.
Mounting the amplifier on the floor of the trunk will work but provides less
cooling capability than vertical mounting.
Mounting the amplifier upside down to the rear deck of the trunk will not
provide proper cooling and will severely affect the performance of the
amplifier and is not recommended.

Passenger Compartment Mounting

Mounting the amplifier in the passenger compartment will work as long
as you provide a sufficient amount of air for the amplifier to cool itself. If
you are going to mount the amplifier under the seat of the vehicle, you
must have at least 1" (2.54cm) of air gap around the amplifier's heatsink.
Mounting the amplifier with less than 1" (2.54cm) of air gap around the
amplifier's heatsink in the passenger compartment will not provide proper
cooling and will severely affect the performance of the amplifier and is not
recommended.
Engine Compartment Mounting
Rockford Fosgate amplifiers should never be mounted in the engine
compartment. Not only will this void your warranty but could create an
embarrassing situation caused by the ridicule from your friends.
