[. . . ] If the amp is properly wired, but the light does not turn on, verify the trigger line is properly connected, is receiving +12 volts, and the speaker outputs are not shorted to themselves or ground in any way. 5. ) INPUT GAIN CONTROL - This controls the gain setting on the input of the amplifier. For high gain settings ( 0. 3 volts), this says that it takes ONLY 0. 3 volts to drive the amp to full output. For low gain settings (near 4 volts), this says that it takes nearly 4 volts to drive the amp to full output. If the amp is often going into distortion at only moderate volume settings on the radio, rotate this control towards the 4 volts setting to reduce the distortion. 6. ) HIGH LEVEL INPUTS - Should RCA cables not be available from the radio you are able to tag onto the audio signal from the high level speaker outputs of the radio. This is most commonly used when the amp is an add-on device such as for a subwoofer system.

These lines are dedicated to left and right outputs of the radio, be it for front or rear speaker installations. The input gain settings of the amplifier (0. 3 - 4 volts) are referenced to these inputs. ­7 ­ POWER CONNECTIONS & SPEAKER OUTPUTS 1 23 Power Terminal (+12V) Connect directly to the vehicle battery + terminal with 10 gage wire (minimum) The power and speaker connections for this amplifier are explained in the summaries below and reference the numbered call-outs above. 1. ) POWER CONNECTIONS GROUND - This is the high current ground connection to the chassis of the car. It should be fastened to a clean ground connection in the car, capable of handling high current loads and within 3 feet (absolutely no longer than 3 feet). TRIGGER - This allows the amp to be remotely switched on from the radio and normally uses a dedicated "trigger" line output. It MUST be fused through its own dedicated fuse at the battery. +12V Spade Connector NOT SUPPLIED To Battery Terminal 10 Gage Wire 30 amp Fuse or Circuit Breaker Battery Terminal Adapter Ground Terminal Connect to a good chassis ground. The ground connection should be clean, unpainted metal to provide a good electrical connection. +12V 2. ) FUSE - This fuse is only for catastrophic situations should the amplifier begin to self-destruct or incur installation situations where gross amounts of current are being required from the amplifier. Although another fuse is located at the battery, in line with the battery high current line, this fuse MUST remain in the circuit to physically protect the amplifier. 3. ) SPEAKER OUTPUT CONNECTIONS - These connections are used to connect to the loudspeakers with the appropriate impedance. It is imperative that these lines NOT be connected or touch the chassis of the vehicle in any way. Also, the (+) and (-) leads are in no way inner connected so the left channel (+) and the right channel (+) must remain independent. In addition, the (-) leads for the speakers CANNOT touch or be wired to the ground lead of the amplifier; these are NOT common ground amplifiers. Spade Connector Ring Connector 10 Gage Wire Sheet Metal Screw Drill 1/8" hole in chassis sheet metal Remote Terminal Connect the radio power antenna lead from the receiver to the amplifier terminal. This turns the amplifier on whenever the receiver is turned on. +12V Important If wiring connections are made wrong, the unit will not operate properly and it could be damaged. Follow the installation instructions carefully, or have the installation handled by an experienced technician.

The resulting performance is most commonly a louder overall sound field from the rear. But, such a system's biggest benefit is the additional bass response since the bass control of the radio can be turned up without distorting the amplifier.
