Hey y'all,

I have a 2008 Chevy Tahoe LS. I don't know why but my speakers have been acting up for a while now. My door/seatbelt chimes get so low that you can barely hear them and sometimes they sound normal. They don't cut out completely though which is confusing to me.

Also, I tried calling Onstar and the speakers do the same thing. The volume gets so low and sounds like the support specialist is so far away. However when I play music, it sounds ok but it doesn't sound like there is really any base and sometimes everything sounds normal again and kicks in all speakers. Sometimes while I'm driving or sometimes when it's a new day and start the car up for the first time. It's really random.

I am the first owner. Bought it brand new. Can someone help me find out what it is?
