3. 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 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

X 54 3 mm X 140 mm Input Impedance Low level 10K Ohms high level 100 Ohms Due to continuing improvement Audiovox reserves the right to change features and design without notice 1 PRECAUTIONS 1 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 thi
7. ate 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 onthe 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 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
