Coulldn't hear rear seat speakers. I have good hearing. Took it to the dealer. He said "They all sound like that". Shortly after they stopped completely. I have one speaker left that works, the passenger door. This is just one of many many problems I have with this oil burning piece of crap, The dealer refused to fix any, he even told me he would get me a bottle of touch-up paint when I pointed the paint flaws out to him. My only new truck ever, and I'll never give GM another cent. I wont even take it back for recalls, I hope it burns to the ground.

2007 Silverado Classic. Front door speakers stopped working after about four years. I finally replaced the stock deck with a Kenwood and that didn't resolve the issue.

Last fall I ohmed out both front speakers and confirmed they were good. I didn't check the wiring for continuity back to the deck at the time but now realize I should have. I assumed it was the deck based on similar problems reported on the Internet.

So, with the new deck and OEM speakers, only the tweeters in the front doors and the rear speakers are working. Tomorrow, I'll take the deck out again to check the wiring to the speakers and probably pull the door panels again to check the speakers again.

Great truck, almost zero issues in eight years, but GM stereo systems absolutely suck. My 2002 Buick Regal had the Monsoon stereo system and it too had severe issues over the years. Failing speakers, inability to play CD's, eject CD's.

All of my speakers quit working except 1 tweeter on the driver's side. it's horrible sounding. The radio works fine except for that. I had to go to Detroit (my hometown) for business, and after driving 11 1/2 hours all of a sudden everything kicked on. (Of coarse the volume was full blast) I thought, great, it fixed itself. Everything worked fine for 3 days, then quit again. I want to fix the problem, but I don't know if it is the radio not sending a signal to the speakers or if it is my speakers. I don't want to replace a perfectly good radio/speaker for nothing.

This was also a major problem when I tried to use OnStar, I could not hear the operator, which caused me to go way out of my way. I'm just glad I didn't have an emergency where I needed the phone or OnStar because without the speakers they both are useless.

Speakers stopped working along with cab light when opening door. Had vehicle in about a month ago for work and asked them about it. Was told that they were not aware of any problems addressing these issue's, and that my speakers were probably going bad. How could the speaker impact the light? Something is rotten in Denmark here, and to stand there and lie to my face- well, this should be investigated and a recall issued to fix an obviously factory (crummy parts) problem. I see that this is a widespread problem after reading this website, and I would think that Chevy would like to retain their customer base and do the right thing here.

Both rear speakers and front right (passenger side speakers--door and at dash level) have no sound. Bought the truck new in August 2007. Problem started occurring after the 3-year, 36000 warranty ran out. I did not purchase additional warranty. I have been putting up with the problem since about December 2010. The "open door with key in ignition" alarm is barely audible and seems to come from the left, front (drivers side--dash level) speaker. I can still hear the radio through the one speaker that is working, but is definitely annoying with rear passengers in ext. cab trying to hear something from the one tiny dash level speaker that works. The problem has moved around over time---certain speakers worked, while others did not, and they eventually quit working until I have what I described above. GM obviously does not use quality parts in their stereo systems. I am not impressed! While very annoying and disappointing, I would like to get it fixed, but can't see spending the money on this, when I have many other pressing priorities for my hard earned income.

Design/engineering defect. Speaker wiring harness wearing. I have On-Star, and of course with that XM Radio, Safe and Sound, etc. The speakers work from time to time, but have a will of their own. Not till i've starting having problems did I find out that a fleet of government GM service trucks I am responsible for, have the same problems. One of my fellow employees just purchased a fairly new Silverado just about like mine, except mine is a 4x4, and, is having same problems. What is really disturbing is that last Tuesday, our area had a downpour of rain and on my way to work noticed a car overturned over an embankment. Three passengers were upside down in their seat belts and couldn't get out. I used my On-Star to call 911 and because the only speaker that was working was on the passenger side pillar, I had to turn up the volume as loud as I could just to hear them. I kept asking the operators and emergency personnel to repeat because I could bearly make out what they were saying. What's disgusting is that the two older cars that I have the stock radio systems and still work fine. I might have to discontinue my On-Star service that GM has been pushing as one of their major purchase package.
