WIRING INSTRUCTIONS 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 #10 gauge or thicker (smaller gauge #) wire for this lead and connect it to the terminal of the battery after all other wiring is completed. GROUND CONNECTION The ground terminal (GND) connection is also critical to the correct operation of the ampli er. Use a wire of the same gauge as the power connection (#10 or thicker) and connect it between the ground terminal (GND) of the ampli er 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. REMOTE TURN-ON CONNECTION The ampli er is turned on by applying + 12V 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 + 12V 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 ampli er on and o with the ignition key, regardless of whether the car stereo is on or o . The remote turn-on lead does not carry large currents. So # 20 gauge wire may be used for this application. SPEAKER CONNECTIONS Depending on the type and number of speakers used with the ampli er 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 # 18 gauge. For leads is excess of 10 feet # 12 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 ampli er. Do not ground any speaker leads to the chassis of the vehicle. 4 www.PyleUSA.com
