buzzing from speaker

[JohnOR]

had this problem for a while now, after i fitted my 6x9s a buzzing noise came from one of the speakers so i unplugged one and been coping with just one but when i plug it in it buzzes but when its unplugged the buzzing goes to the front door speaker, and i dont know if this has anything to do with it but my door light is always lit up on the dash saying my doors are open but theyre not obv, and somtimes the door light on dash goes away and when it does so does the buzzing lol anyone got a cluee? sometimes when i shoogle the headunit it stops but comes back, could it be a bad earth?

It certainly does sound like a bad earth, have you earthed the head unti direct to tye battery? If not, try that.

Blown a fuse most likely. Why did you take it back out the dash if you fixed it?
