My 2006 Chevy silverado 5.3 V-8 is giving me some problems with the radio and speakers. Stock system...no modifications.

Sometimes the radio sound does not work....very low high pitched sound. Sometimes I will have all speakers working.....other times only a few of them work. Not consistent. Sometimes i don't have sound for days...then all of a sudden I have sound. It is consistent in that when I don't have sound....it will not come back no matter how many times I turn the radio on and off. It will only come back after an engine restart...but I never know when.
Not very electrically inclined, but can follow anyones directions if they have a troubleshooting guide or suggestions on what could be wrong.

Can you pull the dash apart and get the radio out??? if so then check the connections it may be grounding out somewhere in the dash..if not a car audio store can trouble shoot for 60 to 80 dollars and if they find something that cant be fixed they can put some of that to the price of a new one like we do at my shop. Hope that helps.

Thanks a lot....I will try that. Its a lot better than taking it to the stealer...uh I mean dealer!!!!!
