Just picked up an '05 base, bought it from an old lady that bought it new so it's stock everything and never been touched. Problem is the door speakers work but if I fade it to the back neither speaker in the rear makes any sound. There's no sound at all what so ever. Both speakers ohm'd out at like 11ohms, so I think they are good? I'm stumped, any thoughts?

Sounds like the speakers are toast. I believe the factory speakers are 4 ohm.

However, your best bet is to simply troubleshoot. If you have another source to hook the speakers to, try that. If you have other speakers to hook up there, try that. You don't have to tear the back of the car apart for this, just take some spare wire and hook things up. My bet is on the speakers, but it could be the wires and/or the radio itself.

i agree with him! ^ or you could just buy new speakers all around, get a deck with sub and speaker rca outputs, and get a small 4 channel amp and don't even use the stock wiring.
