INSTALLATION INSTRUCTIONS INSTALLATION DIAGRAM 1. Select a mounting area where the amplifier will have sufficient air circulation for proper cooling. Inadequate air circulation will cause the temperature of the amplifier to rise and will trigger the thermal protection mode. 2. Place the amplifier on the mounting surface and mark the locations of the four mounting holes as shown in the illustration. 3. Remove the amplifier and drill a 1/8" hole at each of the four locations. CAUTION: Befor

WIRING INSTRUCTIONS The wiring of your amplifier will depend on the system and speakers you are using but will either be a stereo, mono, or mixed-mono application. The following pages illustrate the input and output wiring for these types. please refer to the appropriate diagrams for the system configuration you are using. The power and speakers wire connections for this amplifier are made via screw tightened terminal blocks. Loosen the screw for the connection to be made and fully insert the wi

WIRING INSTRUCTIONS 4. Speaker Connections Depending on the type and number of speakers used with the amplifier, wire them to the speaker terminals as per the appropriate wiring diagram. For most applications, #16 gauge wire should be used for the speaker leads but in no case thinner than #18 gauge. For leads in excess of 10 feet, #14 gauge is recommended. When wiring the speakers, pay careful attention to the polarity of the terminals on the speakers and make certain they correspond to the p
