My speakers have a loud hum when I first turn on the radio. How do I correct this issue.

Does it go away after a while, or is it always there?

It could be bad ignition wires.

It could be a loose ground.

I found on my 1992 that the BOSE amps capacitors were the cause of the hum. If you go to EBay there is a company I believe out of Florida that fixes them for around $50 each. I was able to repair my own. 

Thanks. Can you replace the speakers with ones that don’t require the amps.

I was given this list a couple of years ago and it’s been very helpful. It’s all about the hunt. Have fun!!

Amplifier is toast. Replaced all 4 in my 93. Common problem there is a guy in FL that repairs them a little pricey but done right. He’s actually on YouTube. Each speaker has an amplifier “great job Bose”. Radio was also rebuilt due to CD problems

I was there today and he has LOTS of speakers ready to purchase.

Going back tomorrow for more items!

Great place.  He has multiple warehouses full of parts.

I found that place about five years ago by chance. Saw a couple of C4’s in the yard, the next day I went to see what John had. You’re right you can spend hours in there. He is very cordial and knowledgeable. He’s also on eBay. Have fun!
