I just installed the F900BT in my car and everything works great until you turn on the head lights and fog lights then you get a buzz from the speakers. Has anyone had this problem? Any fix?
I have a 2008 Audi A4 a ton of mods but haven't done anything to the head lights except change the fogs from stock bulbs to yellow bulbs. I also had a complete system from components and amps to a sub installed.
Thanks in advance!
