rear speakers buzzing??

Yes, but 6 people being killed is still to many. I bet you would feel different if your family had just been wiped out by some a-hole in a speeding car!
 
I've recently fitted an aftermarket stereo to my A3 using an autoleads adaptor without the RCA outputs. I've noticed recently i'm getting a buzzing from the passenger rear speaker. I can cure it for a bit if i turn the stereo off for about 5 mins and then turn it back on

any had the same problem?
