For some odd reason, I barely have any sound out of the rear deck speakers, but the sub in the trunk works fine. I even tried fading to just the rear, but I can barely hear any sound out of them, the fronts work fine. Any ideas?

 

Blown maybe? Bad connection? Make sure nothing has come loose.

 

Still stock radio and speakers I would imagine....Could be a blown speaker, but I would lean towars either the radio or the outputs on the amp are bad...either way, pretty rare if it is all stock...

 

I just noticed its an 05 you have. Take that back to the dealership and have them fix it, nothing like that should be going wrong in such a new vehicle unless it was defective.

 

I got an appointment with the dealer Friday morning since I'm off work.
