I fitted a new head unit on Tuesday an In-phase IPX1
everything has been fine with it until i turned my lights on tonight.
When i turn my lights on i get a buzzing sound which only comes out of the tweeter on the passenger side and it gets quieter when i dim the dash lights but does not stop.
If you turn the volume up the buzzing does not get louder and as soon as you turn the lights off it goes away
anyone know what is causing this???
