Well, I finally got around to taking the panel off the rear so that I can mount speakers. Although I've seen posts where people have stipulated that the wiring is already there, there are no speaker wires to mention. WTF? I checked the OE male harness for the headunit and there is definitely rear speaker wires leading out. Are these wires hidden? I know that there is already a provision for rear speakers (looks like 5-1/2") with a bracket hidden behind the plastic panel but no wires. Anyone have a better clue?
