Sudden whine in stereo I have a set up that has been in place for about 5 years now with no issues. In the last few days I have started hearing a faint whine in the music from about 2000-3000 RPM. It is still quite faint but I think it is getting slowly worse.
Is my only choice to replace the whole alternator or can the diode pack be replaced separately? Is it something else altogether?

Agreed about the ground. I had my amps grounded in the same spot (seatbelt bolt) in the rear for a long time and suddenly developed noise one day for no apparent reason. To make a long story short, the solution turned out to be to change to another grounding point and the noise was gone...I guess it developed some sort of ground loop, but once I changed to a different ground point, all was well!

I suppose it could be a ground, although the amps all ground up at the battery. The car is running fine. I noticed tonight I have the famous headlight brightness variations. My car never really had that before. I cannot remember what the cause of that was.

I'm talking about the amp grounds. Typically, you want to ground all amps to the same spot on the chassis to keep from inducing noise. You also want to run your RCA's down one side of the car and then power /ground wires down the opposite side of the car to prevent noise from entering the system.

i have fixed the problem and it has came back a few times already. Even got rid of my older stereo which was very good, got a new one then sometime down the road, same problem. Recently i went to frys and they sell a ground/rca's box to connect to your amp and it has worked great till today, now its making noise again but if I turn off and on the radio i can get it to stop making noise then it comes back again some time later or another day.
i remember there was a thread were someone said the fix was to solder some part that you can get to by removing the glove box. But i don't recall the thread, i thought i had saved it. This person had the same problem and he said this fixed it for him as some of the solder came off some of the componet which made his radio act weird, the thread had pictures and all.
