I got the bose gold system in my 92 rs. its got the cassette not CD. The front right speaker is blown but the problem is that it makes a massively loud high pitched noise that goes on and off randomly. I tried searchin but didnt find anything. Anyone else have this problem and how can i fix it thanks

 

Does the pitch seem to alter with engine speed?

 

naw it doesnt. it just turns on randomly while listenin to tunes. If i turn the system off and back on sometimes its gone but sometimes it is still there.
