InsideBackCover HIGHPERFORMANCESTEREOAMPLIFIERHIGHPERFORMANCESTEREOAMPLIFIER 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. Should you require assistance with the installation or wiring of this unit, please call our toll-free "HELP" line at 1-800-645-4994 during the days/hours shown.

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. By nature of its design, a power amplifier generates heat and requires good air circulation around it to dissipate that heat. Do not install the amplifier in an enclosed area which does not permit adequate air circulation. Should the temperature of the unit rise too high, the internal thermal sensors will shut off operation until it has cooled down sufficiently. 4. If fuse replacement is necessary, use only fuses of the same ampere rating as originally supplied with the unit. The use of fuses with incorrect ratings may cause serious damage to the amplifier. If fuses blow consistently, carefully check all electrical connections to the unit. 5. Supply of adequate battery voltage is critical to the proper operation of the power amplifier. The leads to the battery and chassis groundmust be of a thick enough gauge to provide this voltage to the amplifier. We recommend #10 gauge wire or larger (smaller gauge #) for the battery and ground leads. 6. Make certain that the speaker(s) to be used with this amplifier are capable of handling the output power (wattage) of the unit. Use of speaker(s) not rated for the output of this amplifier may cause damage to or failure of the speaker(s) for which Audiovox will not be liable. -2 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. 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: Before drilling the holes, look at the underside of the mounting surface. Always check carefully to avoid drilling into wiring, braces, fuel or brake lines. CHECK BEFORE YOU DRILL ! 4. Apply a self-adhesive rubber washer to the bottom of the amplifier at each of the 4 screw locations. Secure the amplifier to the mounting surface using the self-tapping screws provided. 5. Attach the plastic end panels to the amplifier by removing the protective paper from the self- adhesive strips on the bottom of the panels and pressing them into position on the amplifier.

The following pages illustrate the input and output wiring for both 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.
