Although this unit is designed with built-in self-protection circuits, there may be a possibility of damage if it is not wired correctly. [. . . ] Remove the amplifier and drill a 1/8" hole at each of the four locations. INSTALLATION DIAGRAM SCREW 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. MOUNTING SURFACE DRILL 1/8" HOLE -3- 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. Loosen the screw for the connection to be made and fully insert the wire (strip 1/2" of insulation from the end) under the respective screw on the side panel (crimp-on "U" terminals are provided to simplify wiring and we recommend their use. ). Tighten the screw down to secure the wire. 1. Power Connection The battery terminal (BATT) must be connected directly to the positive terminal of the vehicle battery to provide an adequate voltage source and minimize noise. Connecting the battery terminal lead to any other point (such as the fuse block) will reduce the power output and may cause noise and distortion. Use only #16 gauge or thicker (smaller gauge #) wire for this lead and connect it to the terminal of the battery after all other wiring is completed. 2. Ground Connection The ground terminal (GND) connection is also critical to the correct operation of the amplifier. Use a wire of the same #16 gauge as the power connection (#16 or thicker) and connect it between the ground terminal (GND) of the amplifier and a metal part of the vehicle close to the mounting location. This wire should be as short as possible and any paint or rust at the grounding point should be scraped away to provide a clean metal surface to which the end of the ground wire can be screwed or bolted. 3. Remote Turn-On Connection The amplifier is turned on by applying +12 volts to the remote turn-on terminal (REM). The wire lead to this terminal should be connected to the "Auto-Antenna" lead from the car stereo which will provide the +12 volts only when the car stereo is turned on. If the car stereo does not provide an Auto-Antenna lead, the remote turn-on lead may be wired to an "Accessory" or "Radio" terminal in the car's fuse block. This will turn the amplifier on and off with the ignition key, regardless of whether the car stereo is on or off. The remote turn-on lead does not carry large currents, so #20 gauge wire may be used for this application. -4- 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. [. . . ] 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. -8- 1 Power Indicator Lamps The Power Indicator Lamps 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. 90 DAY/12MONTH LIMITED WARRANTY Applies to car stereo power amplifiers, equalizers and accessories.
