What is it?

This wire harness provides a line out converter for connection to one set of RCA cables to provide an audio signal to an external amplifier.  Also pre-installed on the harness is a remote amplifier turn on wire.  This wire, along with a set of RCA cables, is run to your aftermarket amplifier.  All that’s left for you to do is connect your own main power wire from your battery and a ground.

What you will receive
One (1) plug and play wire harness
One (1) 10ft RCA cable

Compatibility Notes

-Audio volume to the amplifier can be adjusted by the dials on the harness.  For easier access we recommend using an external volume knob.(Not included but we can provide one)
-A variety of wire colors may be used for the remote wire coming off the harness.  Regardless of color, rest assured it is for the remote turn on of an amplifier.
    Converter adjustment instructions:
    1. After completing all of the necessary connections, turn the adjustment pots all of the way down by rotating them completely counter-clockwise.
    2. Turn the stereo system on and adjust the main volume control on the stereo to approximately 3/4 maximum volume.
    3. Select one of the adjustment pots and turn it slowly clockwise until you notice audio distortion and then stop.
    4. Turn the remaining pot to the same position as the previously adjusted pot.
