Has anyone else had to replace their door speakers? 2008 Silverado 3500HD Duramax with less than 9,300 miles on it. Just recently the chime became barely audible which was no big deal until I tried to make a phone call and couldn't hear ON STAR either. Went to the dealer and found that both door speakers had to be replaced. $150.00 later everything is working fine but find it hard to believe that both speakers went bad with less than 9,300 on the truck and the fact that the inside of the doors have never had much exposure to rain, snow, etc. I am a very loyal Chevy owner but currently a very dissatisfied customer.
