Forgive me if this sounds like a daft question, but I want to wire in some rear speakers to an already fitted after market stereo, it looks like everything is wired in ok at the head unit end, but I'm having trouble finding the ends of the wires for the rear speakers... did jeep leave these in any particular place ? I cant pull the harness, or any wires up from where the dissapear down the back of the heater and cant see them anywhere underneath the dash area, it's a 98 with no sound bar...
