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 ground must be of a thick enough gauge to provide this voltage to the amplifier. We recommend #16 gauge wire or thicker (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 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: 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. Secure the amplifier to the mounting surface using the self-tapping screws provided. -3 CONTROLS AND INDICATORS 2 3 41 2 65 8 7 9 -4 . Power Indicator/Protection Mode LED The Power Indicator LED will light to indicate that the unit is connected to the battery and that the Remote Turn-On terminal is receiving +12 volts, thus turning on the amplifier. This LED illuminates red to indicate that the self-protection circuits have been activated and have shut off operation of the amplifier. The protection circuits may be triggered by the temperature of the unit rising above a safe level or by an overload condition. If activated by a rise in temperature, the unit will resume operation after cooling off to a normal operating range. If activated by an overload condition, the source of the overload must be found and corrected to resume operation of the amplifier. Most overload conditions are caused by mis-wiring or operation into incorrect speaker loads. Re-check all wiring and connections if this situation occurs and correct as necessary. . Level (Gain) Control The amplifier is capable of operating from sources supplying a wide range of input levels. The Level control 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. If, however, there is still output from the amplifier when the car stereo volume control is at i...
