HIGH PERFORMANCE STEREO AMPLIFIER This power amplifier has been designed to provide high Quality performance with a minimum of maintenance. However, it's performance will only be as good as the care and quality of components with which it is installed. We therefore advise that you read these instructions very carefully to familiarize yourself with the product and it's features.
PRECAUTIONS 1. Although this unit is designed with built-in self-protection circuits, there may be a possibility of damage if it is not wired correctly. Please follow the wiring instructions carefully for the type of system being used. 2. The last lead to be connected is the wire to the positive(+) terminal of the battery. Connect this wire only after having completed and checked all other connections to the amplifier. 3.
INSTALLATION DIAGRAM INSTALLATION INSTRUCTIONS 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. SELF-TAPPING SCREW 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.
WIRING INSTRUCTIONS The wiring of your amplifier will depend on the system and speakers you are using but will either be a 4-Channel, 3-channel, 2-channel, 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 speaker wire connections for this amplifier are made via screw tightened terminal blocks.
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, #18 gauge wire should be used for the speaker leads but in no case thinner than #20 gauge. For leads in excess of 10 feet, #16 gauge is recommended.

FAILURE TO WIRE CORRECTLY MAY CAUSE DAMAGE TO THE AMPLIFIER. EXISTING SCREW OR BOLT CLEAN PAINT, RUST, DIRT OR GREASE FROM AREA FOR GOOD CONNECTION.
OPERATION 2 2 Level (Gain) Controls 1 The amplifier is capable of operating from sources supplying a wide range of input levels. The Level controls should initially be set to the mid-rotation position. If it is found that there is not enough output even when the volume control on the car stereo is at its maximum setting, adjust the Level control to increase the output from the system.
