i just picked up a 2010 mkx this afternoon and the front speakers are distorting (mainly the front center, but i hear it slightly in both the front left and right)
it seems to be a ground issue. if i turn the headlights on, the distortion starts. turn them off, it goes away. turn the volume up a bit and you cant hear it.
has anyone ever heard of such an issue? im planning on yanking the dash apart and search for a grounding issue. maybe dig out the amp and check the grounds on that too.
