Wiring graph for these subs please?

I know this isn't an answer to your question, but you have decent subs and a GARBAGE amp. Hitron is seriously the worst of the worst. When I was an installer and someone had and amp that sucked we would say "well, it's better than a hitron." From ground noise, to poor sound, to exaggerated power ratings, to freakish problems, to outright failure the Hitron's sucked in every way that an amp can suck. Do your P2's justice and get a better amp. Assuming you heed my advice, you would want an amp that is around 250x2 RMS @2ohms or 500x1 RMS at 4ohms (best bet would be a 2-channel amp that is bridgable).
