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/ PowerPlateTM 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.

Before cutting or drilling carefully inspect the area to make sure there is no electrical wiring, fuel lines or brake lines which could be damaged. Sometimes these components may be hidden between double-walled panels, so be very careful.

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 PowerPlateTM with speakers which have either terminal connected to the speaker frame or to the vehicle chassis.

Mounting locations

PowerPlateTM in a place that protects it from the elements. In addition, mount the PowerPlateTM 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 PowerPlatesTM have been designed with a low profile to make under seat mounting possible. Regardless of where you choose to mount your PowerPlateTM 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 Power- PlateTM chassis vertically with the fins running vertically, or mount the PowerPlateTM horizontally with the fins pointing upward. Avoid horizon - tal mounting locations with the fins pointing downward.

Also, locate the PowerPlateTM 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.
