Same Side Adjustments – The P-series PowerPlate™ makes system adjustment easy by organizing all signal processing controls on one side of the amplifier. This layout allows convenient system adjustment and facilitates a variety of installation possibilities when access to the controls is desired. 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. 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. Never operate the vehicle without the PowerPlateTM 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 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 PowerPlateTM chassis vertically with the fins running vertically, or mount the PowerPlateTM horizontally with the fins pointing upward. Avoid horizontal 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 PowerPlateTM was not designed to endure the harsh chemical and heat environment of the engine compartment. Failure to obey this warning will void your warranty. symptom poor bass response battery fuse blowing amplifier fuse blowing possible cause Speakers wired with wrong polarity causing cancellation at low frequencies crossover set incorrectly impedance load to amplifier too low short in power wire or incorrect power connections fuse used is smaller than recommended too much current being drawn impedance load to amplifier too low or wired 2 stereo or 4 mono short in power wire or incorrect fuse used is smaller than too much current being drawn action to take check speaker polarity and repair as needed reset crossovers referring to the multi-crossTM crossover configuration section of this manual for detailed instructions check speaker impedance load, if below 2 stereo or 4 mono rewire speakers to achieve a higher impedance check power and ground connections and repair as needed replace with proper fuse size check speaker impedance load, if below 2 stereo or 4 mono rewire speakers to achieve a higher impedance check power and ground connections and repair as needed check speaker impedance load, or 4 mono, rewire speakers to achieve a higher impedance check power and ground power connections connections and repair as needed replace with proper fuse size recommended check speaker impedance load, if below 2 stereo or 4 mono rewire speaker to achieve a higher impedance check power and ground connections and repair as needed troubleshooting symptom no output audio cycles on and off distorted output possible cause action to take low or no remote turn-on check remote turn-on input voltage output at amplifier and correct as needed fuse blown check power wire integrity and reversed polarity, repair as needed and replace fuse power wires not connected check power wire and ground connections and repair or replace as needed audio input not connected check input connections and or no output from source signal i...
