LOL I'd say there should be wires back there but you never no. When I bought my Integra there wasn't any speakers and no wire. It sucked. I had to get a wiring diagram to find the wire that went from the headunit wiring harness and then splice in 12 gauge wire into it get it to the holes in the rear. Front was the same just way harder. That is what you might have to do if there aren't any wire in the rear. But im sure there somewhere back there. It is hard when you first start out, but yall get the hang of it.
