I have a 2017 custom with the built in screen for reverse park/stereo track info etc, and want to upgrade the stereo, adding an amplifier and replacing the speakers, possibly also adding a subwoofer and rear speakers. I want to retain the built in head unit though as it doesn't seem that bad and want to retain the screen functionality.
Is is there an adapter available that can be connected between the stereo and the existing wiring connector that will provide RCA outputs to go to an external amp to avoid having to locate and cut the existing wiring? I guess I would have to connect a line level adapter between the head unit and the amplifier too. If anyone has a wiring diagram of the connectors/wiring colours that would also be helpful.
thanks
chris
