CONNECTING THE POWER CAUTION: AS A PRECAUTION, DISCONNECT THE POWER WIRE FROM THE BATTERY WHILE MAKING THE POWER AND GROUND CONNECTIONS TO THE AMPLIFIER. 4/8 GAUGE(Thicker if planning for additional Amplifiers) wire is recommended for both the power and ground wires 12 Gauge, for the remote turn-on wire 16 Gauge. Both types are available at most Mobile Audio Dealers or Installation Shop. (1) Ground : To Vehicle Chassis To avoid unwanted ignition noise caused by ground loop, it is essential that the Amplifier be grounded to a clean, bare, metal surface of the vehicle's Chassis NOTE : GROUND WIRE SHOULD NOT BE EXTENDED MORE THAN 3 FT. (1 METER). (2) +12 Volt(Fused) Constant Power: To Battery (+) Due to the power requirements of the Amplifier, this connection should be made directly to the positive (+) terminal of battery. For safety measures, install an in-line Fuse Holder (not included) as close to the battery positive (+) terminal as possible with an ampere rating; not to exceed total value of fuses in Amp. (3) Remote Turn-On Input: To remote turn-on output of Car Stereo This Amplifier is turned "ON" remotely when the vehicle's stereo is turned "ON". NOTE : IF YOUR RADIO DOES NOT HAVE A +12 VOLT OUTPUT LEAD WHEN THE RADIO IS TURNED ON, THE "REMOTE" TERMINAL ON THE AMPLIFIER CAN BE CONNECTED TO VEHICLE'S ACCESSORY CIRCUIT THAT IS LIVE WHEN THE KEY IS "ON". < 5 >
