My 89 Iroc has the complete Bose system in it. I bought the car a couple years ago. I get a little fuzzy sqealing noise out of the right rear speaker and nothing out of the left rear. The right kick panel speaker makes a pop noise when you turn on the radio but that is the only sound you get out of it. The left kick panel speaker does work. I pulled out the radio to make sure the plugs were all plugged in. There is a black plug a white plug and a blue plug plugged into the radio. There is another blue plug and white plug laying under the radio. After wiggling the wires around for a while in different places now the sound from the good speaker quits after about 5 minutes and then comes back on a couple minutes later and continues that cycle , but I think the power stays on to the radio cause the clock never goes out. 1. Is there a breaker somewhere? 2.Why the extra plugs? 3.Is it possible that the previous owner has tried using another head unit and blown the speakers? Thanks for any and all help!!!!!!!!!

I have a bose system in my car and I will try to answer your questions. As far as I know, there is no circuit breaker for the stereo, but there is a relay for the bose amps. I would say its an amp turn on relay. Not forsure where its located, but its probably under the dash. My iroc has 2 sets of plugs for the radio also. The one not being used is for a standard oem radio, which all camaros should have(even the regular speaker wires are ran in a bose equipped car), but if you got the bose system, it used a separate wire harness which was added along with the standard radio harness. I had static and noise coming from my right rear speaker along time ago. It turned out to be the amp on that speaker. The electrolyte in the capacitors in the amps breaks down over time and causes noise and static to come from the speakers. I replaced that amp in my car and the noise was gone. So you might just have some bad amps causing your problem. Its possible that the previous owner did a little hacking of the wire harness to put in an aftermarket stereo or didnt bypass the amps correctly, or at all, with the aftermarket radio and blew the speakers or damaged the amps. If he wired up the aftermarket radio and didnt bypass the amps, you would only be able to turn up the volume very little and would be like its turned up full blast. You are amplifing the sound twice, once from the radio and again thru the bose amps with a possibility of popping when you turned on the radio and changed stations. I would check the wiring at the amps and at the radio to make sure there ok and if there ok, I would say that the amps are bad. Sorry so long but I hope this helps.

Thanks for the info!!!!!!!!!!
