warnings and tips

Always disconnect the battery ground wire before doing any work on your vehicle. Reconnect the
cable only after the installation is complete and the wiring has been checked to make sure that there
are no problems. If your radio features a code type security system, be sure you know the code
before disconnecting the battery!
Your a/d/s/ PowerPlate

TM 

should be installed in 12V negative ground vehicles only. Connection to

other types of electrical systems may cause damage to the vehicle or the amplifier.
Wear Eye and Ear protection when using power tools.
Do not bypass or modify the fuses, or replace with one of a higher rating. The fuse should not fail
under normal operation. Repeated blowing indicates a problem with the amplifier or improper
installation.
An additional power supply line fuse (not supplied) must be installed on the 12V supply line and
located as close as possible to the battery in order to protect the wire in the event of a short circuit.
Make sure the system is turned off when making or breaking any connections.
Do not use your PowerPlate

TM

with speakers which have either terminal connected to the speaker

frame or to the vehicle chassis.
Never operate the vehicle without the PowerPlate

TM

firmly mounted. An unmounted amplifier can be

a dangerous missile in an accident or abrupt stop.

mounting locations

Due to its low profile, there are many possible choices of mounting locations. Always mount the
PowerPlate

TM

in a place that protects it from the elements. In addition, mount the PowerPlate

TM

on a

stable, flat mounting surface. Whenever possible, pre-drill the mounting holes. Remember to check
behind the panel for hidden dangers in the form of hoses, fuel or brake lines or electrical wiring. Use
a marking pen or awl to mark the hole locations and pre-drill using a 1/8” bit.

Passenger compartment mounting: All PowerPlates

TM

have been designed with a low profile to make

under seat mounting possible. Regardless of where you choose to mount your PowerPlate

TM

be sure

to keep a minimum of 1” of clearance around the amplifier for adequate airflow to prevent
overheating.

Trunk compartment mounting: The most common mounting location is in the trunk or cargo
compartment. For optimum cooling, mount the PowerPlate

TM

chassis vertically with the fins running

vertically, or mount the PowerPlate

TM

horizontally with the fins pointing upward. Avoid horizontal

mounting locations with the fins pointing downward.
Also, locate the PowerPlate

TM

where it, and connections to it, will not be damaged by cargo or tools

which may shift during vehicle operation.

Engine compartment mounting: Don’t even think about it! The PowerPlate

TM

was not designed to

endure the harsh chemical and heat environment of the engine compartment. Failure to obey this
warning will void your warranty.
