Hello everyone,
I just attempted to install a 9" android head unit from Eonon (GA9150KW), I got it wired up and turned it on for a test and no audio! So looking online I found that the Harmon Kardon amp might be my problem.. Apparently it needs a 12 volt signal to prompt it to power on. I have seen a few threads that mention this but don't go into great detail. One said to splice a 12 volt power source and connecting it to the blue and White wire.... Anyone have more experience with this? I'm am not sure what wire would be the amp signal. Thanks!
