And what do you mean by this? I have a 93, and I thought all Z's came with bose rear speakers? The wires were still there, half cut and left dangling, so I had assumed that they came from the bose speakers. Where else would they have come from? I do have the rear bose enclosures that I purchased off another member, and I tried to plug them in but no sound came out when I turned up my stereo. Thank you all again for the info though, I'll see what I can work up when I buy my new HU and speakers.
