What you could do is get the d2 version, and when you want SQ, wire the coils in series, and for SPL, wire in parallel for 1 ohm and 1200W RMS. You'll be fine with the power IF you're careful, but usually 800 watts or so is great for those subs, they're very efficient. Sealed box actually has more excursion above tuning, remember that. Ported offers greater cone control above tuning.
