Mounting 

When selecting a location to mount your Kicker amplifier be

sure it is structurally sound and that there are no items behind
the area that could be damaged by the screws. Check for brake
lines, fuel lines, gas tanks, or wiring harnesses etc. 

All amplifiers generate heat under normal operation. Be sure to

choose a location that allows adequate ventilation for the 
amplifier. Also consider that the air temperature inside an 
automobiles trunk can reach upwards of 140 degrees fahrenheit.
An amplifier mounted here may require additional cooling tactics
such as fans or venting to allow cool operation. If possible,
mounting the amp in the passenger compartment will allow 
cooler operation.

Remember that the controls on top of the amp will need to be

accessible for adjustment later. Keep this in mind as you choose
your amplifier’s mounting location. 

Now that you are ready to mount your amplifier, use the 

supplied 3mm allen wrench to remove the amplifier EndKap. This
will give you access to the mounting holes in the amplifier and all
wiring connections. 

With the EndKap removed, drill 4 holes using a 7/64” drill bit

and use the supplied #8 screws to mount the amplifier.
