Boss 612 To amplifier and subwoofers?

No remote wire from amp, one says power ant/remote. So can I take remote from amp and twist with the red power wire from radio and harness so all 3 together? How do I wire this remote wire… Also 2 RCA on back will run to my amp right on a answer someone said no and I don't get that cause there is 2 RCA on back of radio… Help anyone? Also black ground I need put to metal? Don't this just get wired to harness that clicks in harnes from my car? I have a harnes from car and bought the adapert harnes also to go to stereo… Yet no remote,rather not run to fuse box. I see people vote down those answers yet don't give better…
