INSTALLATION INSTRUCTIONS MOUNTING SURFACE DRILL 1/8" HOLE SELF-TAPPING SCREW 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 therespective 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 anadequate voltage source and minimize noise. Connecting the battery terminal lead to any other point (such as the fuseblock) will reduce the power output and may cause noise and distortion. Use only #16 gauge or thicker (smaller gauge #16 #) 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 samegauge as the power connection (#16 or thicker) and connect it between the ground terminal (GND) of the amplifier and #16 a metal part of the vehicle close to the mounting location. This wire should be as short as possible and any paint or rustat the grounding point should be scraped away to provide a clean metal surface to which the end of the ground wire canbe 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 terminalshould be connected to the "Auto-Antenna" lead from the car stereo which will provide the +12 volts only when the carstereo is turned on. If the car stereo does not provide an Auto-Antenna lead, the remote turn-on lead may be wired toan "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 gaugewire 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. When wiring the speakers, pay careful attention to the polarity of the terminals on the speakers and make certain they correspond to the polarity of the corresponding terminals on the amplifier. DO NOT ground any speaker leads to the chassis of the vehicle. 5. Input Connections This amplifier features both high and low-level input capability. Use either the low-level or high-level inputs, not both. If low-level outputs are provided from the car stereo, it is recommended that the low-level inputs be used for lowest distortion and best performance. Use good quality shielded audio cables with RCA plugs at both ends to connect the stereo to the amplifier and keep the cable lengths to a minimum to avoid noise. If the car stereo does not provide low-level outputs, the amplifier may be connected via the speaker (high-level) outputs from the stereo. Wire the speaker leads from the car stereo to the 5-pin adaptor harnesses as shown in the diagram (shielded cable is not required for this application) and plug the connectors into the mating High-Level Input socket on the amplifier. Carefully splice and insulate all wire connections. CAUTION: Use either the low-level or the high-level inputs on the amplifier. DO NOT use both input levels at the same time. -5 INPUT WIRING DIAGRAM Right Speaker CAR STEREO Left Speaker Right Speaker Left Speaker RCA TYPE SHIELDED EXTENSION CABLES Gray (NOT INCLUDED) Brown Black Green White LOW-LEVEL INPUT HIGH-LEVEL (SPEAKER) INPUT (WIRE SIDE VIEW) IMPORTANT USE EITHER HIGH-LEVEL OR LOW-LEVEL INPUT, NOT BOTH.
