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. symptom distorted output (cont’d) poor bass response battery fuse blowing amplifier fuse blowing possible cause action to take speakers are blown check system with known working speakers and repair or replace as needed Speakers wired with wrong check speaker polarity and polarity causing cancellation repair as needed at low frequencies crossover set incorrectly reset crossovers referring to the multi-crossTM crossover configuration section of this manual for detailed instructions impedance load to amplifier check speaker impedance load, too low if below 2Wstereo or 4Wmono rewire speakers to achieve a higher impedance short in power wire or incorrect check power and ground power connections connections and repair as needed fuse used is smaller than replace with proper fuse size recommended too much current being drawn check speaker impedance load, if below 2Wstereo or 4Wmono rewire speakers to achieve a higher impedance check power and ground connections and repair as needed too much current being drawn Check speaker impedance load, if below 2Wstereo or 4Wmono rewire speakers to achieve a higher impedance and replace with recommended fuse size check power and ground connections and repair as needed fuse used is smaller than replace with proper fuse size recommended 3 24 Troubleshooting symptom possible cause action to take no output low or no remote turn-on input check remote turn-on 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 or no output from source check input connections and signal integrity, repair or replace as needed speaker wires not connected check speaker wires and repair or replace as needed audio cycles on and off speakers are blown check system with known working speaker and repair or replace speakers as needed thermal protection engages when amplifier heatsink temperature exceeds 90° C make sure there is proper ventilation for amplifier and improve ventilation as needed loose or poor audio input check input connections and repair or replace as needed distorted output amplifier level sensitivity set too high; exceeding maximum output capability of amplifier reset gain referring to the tuning section of the manual for detailed instructions impedance load to amplifier too low check speaker impedance load if below 2Wstereo or 4W mono rewire speakers to achieve a higher impedance shorted speaker wires check speaker wire connections and repair or replace as needed speaker not connected to amplifier properly check speaker wiring and repair or replace as needed refer to the installation section of this manual for detailed instru...
