How can I fix the back speakers not working in my Ford Fusion?

[Nicko]

So my rear speakers in my 2012 Fusion just decided to quit on me. Front ones are fine, but the back? Nada. I’ve checked the fuses, and everything looks good. I’m no audio expert, but I’m wondering if anyone else had this problem and found an easy fix? I don’t want to rip my doors apart if there’s something simple I’m missing. Help!
