wonder if you could give me a quick hand. I haven't got into it yet but am going to be installing all new speakers into my new to me 87 with CSII. I have read and re-read all the threads on it. I know I have to wire in series but where exactly am I making the splices, behind the radio in the harness or at the doors? Thanks in advance. I haven't done stereo work in many many years.. appreciate the help.
