· At the installation sites, locate and make a note of all fuel lines, hydraulic brake lines, vacuum lines and electrical wiring. Use extreme caution when cutting or drilling in and around these areas. · Choose a safe mounting location away from moisture. · Make sure there is sufficient air circulation at the mounting location for the amplifier to cool itself. · Mount the amplifier, using the supplied hardware.

Repeat for rear speakers, using the Rear L+ and L­ terminals, and the Rear R+ and R­ terminals. · Three-channel operation: Connect the stereo speakers to the Front terminals, as above. Connect the single speaker into which the amplifier's rear channels will be bridged to the Rear R+ and Rear L­ terminals. · Two-channel (bridged) operation: Connect one speaker to the Front R+ and Front L­ terminals. Connect the other speaker to the Rear R+ and Rear L­ terminals. · Minimum speaker impedance for stereo operation is 2 ohms. Minimum speaker impedance for bridged operation is 4 ohms...
