Got that great GM f***ing.

All four of my wife's 2007 Tahoe speakers suddely started acting up. Still have sound, but it sounds real tinny, no bass. Also no seatbelt warning. Tried to adjust the bass level, but did no good. Checked the fuses (#40 & #41) and they seemed ok, but I didn't use my meter on them. She took it to the dealer and they said *ALL*FOUR*SPEAKERS* were bad!! How is that possible? She is in her fifties and doesn't crank the thing up.

Everything stock I assume? did they even check to see if it could've possibly been a problem within the radio?

It is a factory unit, with an external CD changer. Don't know what they checked, she told me about it after I got home (they'd already closed). Hadn't got the service order yet because they only had two speakers in stock and had to order two more. That's right... she went ahead and told them to install two of them.

Hmmm to be honest I would of never took it to the dealership, unless it's under some sort of warranty. I would of found a really good, reliable local car audio shop and had them diagnose it. That's exactly what I would expect them to do is tell you all of them were bad haha a second opinion from another shop would be good.
