i dont have the sub yet but i will be getting it within the next couple of weeks
i used a kicker zx1500.1 wired to 1 ohm with the D6s. gain wasnt even past half and they were gettting about 750 each.
i didnt want to run them at one ohm but that was the only option with that amp and the 2 D4 subs.
i am however going to run my single 12 at 2 ohms.
