heres what u do, wire 2 of the coils in series to a 4 ohm load, and the other 2 coils to series to a 4 ohm load, then after this is done, wire both 4 ohm loads in paralell to get a 2 ohm load
god damn crazy quad voice coils...they ever come out with a sub with more then quad...like octagon voice coils...i'm gonna have to go into the store and just slap the owner of the store, "what are you thinking, how many hours do i look like i have to wire this beast, pay you to do it...i'd rather be attacked by rabbid wolves"
You can get quad voice coils from a few different companies. Since I ordered an RE sub, I know you can get them to build you a quad 1 or 2 sub. I'd imagine they'd build quad 4 ohm as well. Dual 1, 2, or 4. The triple X's come standard dual 2 though.
