Choosing a Location and Mounting the Amplifier Amplifiers need air to stay cool. Suitable locations are under seats (provided the amplifier doesn’t interfere with the seat-adjustment mechanism), in the trunk or in any location that provides enough air for the amp to cool itself. Do not mount the amplifier with the heat-sink fins facing downward; this makes convection cooling of the amplifier impossible. Mount the amplifier so that it is not damaged by the feet of back-seat passengers or shifting cargo in the trunk. Mount the amplifier so that it remains dry – never mount an amplifier outside the car or in the engine compartment. Using the amplifier as a template, mark the location of the mounting holes on the mounting surface, drill pilot holes and attach the amplifier to the mounting surface with screws. Make sure the amplifier is mounted securely. Wiring the Power Connections Refer to Figures 1–4 for connector locations. Use at least 10-gauge wire for power and ground connections. For power, remote and ground connections strip off one end of each jacket to reveal bare wire for insertion into the barrier-strip connectors. Connect a wire from the GND connector on the amplifier to the nearest bare-metal chassis component; scrape away the paint to ensure good conductivity. Next, connect a wire between the BATT terminal on the amplifier and the POS (+) terminal of the vehicle’s battery. Pass the wire through a factory-installed grommet in the firewall, or install a grommet if a factory grommet is not available. You must install, within 18" of the battery connection, a fuse holder and fuse with the same rating as the fuse in the amplifier’s chassis. This will prevent a short circuit from causing damage to the amplifier or the car. Connect a wire between the REM terminal of the amplifier and the “remote out” or power-antenna lead on the vehicle’s radio. Wiring the Speaker-Output Connections Connect the speakers, observing proper polarity, to the speaker-output barrier strip. The total impedance of the speaker system connected to the amplifier when the amplifier is driven in stereo must be at least two ohms. If you are bridging the amplifier, connect the speaker wires to the termi- nals marked “bridged,” observing proper polarity. The total impedance of the speaker system connected to the amplifier must be at least four ohms in bridged mode. If you are running the amp in Tri-Mode (stereo and mono simultaneously), connect the satellite speakers to the speaker connector as you would a pair of stereo speakers. Connect the subwoofer to the terminals marked “bridged.” Refer to the chart bel .....
