WIRING AND INSTALLATION
1. Make sure that the vehicle is turned off and if possible disconnect the
negative battery terminal to prevent any accidental shorts.
2. Remove the OEM radio. Please see your local car audio professional if you
have questions or problems doing this.

4. Plug the “T” harness into the OEM radio, the OEM harness, and into the
CHRY-AMP-03 interface.
5. Connect the BLUE/WHITE wire from the CHRY-AMP-03 interface to the
remote turn on of the aftermarket amplifier.

LEVEL ADJUSTMENT
If after setting the amplifier gain properly the output is still too low or high, you
can increase/decrease the level at the CHRY-AMP-03. Locate the potentiometer
on the CHRY-AMP-03 which is next to the 10 way Molex plug. Turn the radio on
and use a small Phillips or Flathead screwdriver turn the potentiometer up or
down to adjust the level up or down.
NOISE ISSUE

that noise is present. If that is the case follow these steps:
1. Make sure the vehicle is turned off.

shunt on 2 of the pins.

4. Close up the CHRY-AMP-03 interface and turn vehicle on to test.
