I folded my rear seats down for the first time today. I found a couple 8 gauge wires for power and ground, a control wire (all power is dead obviously) and some line level inputs. I have the factory stereo (non-bose) and I assume these were for some kind of tube or something. I didn't think there was a way to do pre-outs on the factory stereo. I haven't taken the dash apart to see what they could be hooked to, anyone have any ideas what I will find when I open it up?

 

Good question, anybody got an answer?
