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, see other store listings!)
It is up to the installer to select which circuit to use with the Add-A-Circuit. The radio circuit is most common however any that turns on/off with the ignition could be used if deemed appropriate.
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.
