OK, I have a 1994 z28 with the passenger speaker ducts with no speakers in them so I am going to put some in there. Here is my question. Where is the factory wiring to go to these speakers? Do they purposely not put any in there if you have a base model? Or are they really hidden well in their? I seen the wiring harness but left and right rear points to the trunk speaker.

 

what kind of stereo do you have cuase in my 93 the bose stereo that came with it was three crappy speakers and there were no extra wires anywhere. Just run new better ones to all your speakers. Its the best way to go.
