Do you have the Bose Gold system?? It sound like one of the speaker amps are going out if the noise is from one paticular speaker or the speaker relay is going bad if the sound is coming from all of them.

c4cruiser is right, that is a classic sign of failing amps if you have the Bose sytem. It only gets worse from here as the capacitors slowly die out. You can get them rebuilt by Bose or (cough) gut the Bose and put in a whole new system.

Ditto on the diagnosis - one of the amps is going bad.

Ecklers and MidAmerica sell replacement amps and they are easy enough to replace. There are places that rebuilt them also. Do a search here as there are several threads on these things.

Normally, all you need to replace is the amps located with each speaker to fix this problem.

send me an e-mail...I have found a radio repair shop in Surrey that does excellent work and will repair your bose system. Several of us in the club have gone there.
He rebuilt both rear speaker amps for me for $263.35 CDN (taxes in) and another time he soldered a loose terminal on my left rear speaker for $40.08 CDN (taxes in). He does good work and isn't of the "replace it" mentality.

Before you get too excited about paying $263 it breaks down this way...

Rebuild 2 amps - $165
Re & Re - $65
GST - $16.10
PST - $17.25

Total - $263.35

I agree with Onedef. The Dr. has superior service and fast turn around times.

Another option is to just replace the capacitors, while this may not fix all the amps it did fix two of mine so far, which were doing the same thing as yours. If you can do basic soldering (or know someone who can) it is worth a shot IMO. You can get the caps from radioshack for about $6. There are instructions floating around the forums, and it is pretty easy to do. You can remove the speaker grill and housing and unplug the amp to find which one is the problem, if you are having trouble finding which speaker it is.
Good luck.

I too have the same problem with my bose gold stereo. I get the squeel after a few minutes after its turned on. It does seem to come from all the speakers. I also hear a low pitched rumble. Could it be the relay. I cant believe all the amps are bad. Where is the relay you speak of. Thanks
