1. Wiring Harness - All wiring to the amplier will run through the wiring harness.
Speakers - Connect speakers/subwoofers to these terminals. Be sure to check wire for proper
polarity. Never connect the speaker cables to the chassis ground.
+BATT (+12 Volt Power) - Connect this terminal through a FUSE or CIRCUIT BREAKER to the
positive terminal of the vehicle battery or the positive terminal of an isolated audio system
battery. WARNING: Always protect this power cable by installing a fuse or circuit breaker of the
appropriate gauge within 18 inches (45cm) of the battery terminal connection.
Remote Turn On - This terminal turns on the amplier when (+) 12 volt is applied to it. Connect it to
the remote turn on lead of the head unit or signal source.
GND - Connect this cable directly to the frame of the vehicle. Make sure the metal frame
has been stripped of all paint down to the bare metal. Use the shortest distance possible.
If a suitable ground point is not available on the frame, connect this terminal directly to
the vehicle battery ground terminal, or any other factory ground points.
RCA Input Jacks - This unit is designed to function with source units that feature RCA outputs. If
your source unit does not have RCA outputs you will need to use the speaker level inputs.
A source unit with a minimum level of 200mV is required for proper operation.
2. Gain Control - The Gain control will match the amplier’s sensitivity to the source units signal
voltage. The operating range is 10V to 200mV. NOTE: This is NOT a volume control.
3. X-Over Mode - These controls allow control over the frequencies played. There is an option for
Full, 80Hz, or 200Hz on the front channels, and an option for Full Range, High Pass, or Low Pass on
the rear channels.
