2 X 50 Watt Truck Amp (120-1971) Connecting Power Faxback Doc. # 6714
Follow these steps to connect power to the amplifier.
1. Disconnect the positive (+) wire from your vehicle's battery. This
reduces the possibility of damage to your system during
installation.
NOTE: You must reset the clock, the radio's digital tuner
memories, and other time/memory devices when you
reconnect the battery wire after wiring is complete.
2. Connect the amplifier's black (ground) wire to a nearby part of the
vehicle's metal frame.
NOTE: Many modern vehicle parts are made of plastic or other
materials that do not conduct electricity. You must
connect the black (ground) wire to a metal part that is
not insulated from the vehicle's frame by one of these
non-conducting parts.
3. Connect the red (power) wire directly to the car battery's + 12-volt
power source.
CONNECTING THE SWITCHED POWER LEAD
Follow these steps to connect the switched power lead.
1. Connect the supplied orange wire's male quick disconnect plug to
your car stereo system's switched power output lead.
2. Connect the orange wire's other end to the amplifier's REM (Remote)
terminal. With this connection, the amplifier turns on/off when
you turn on/off your car stereo system.
