you can only go 4 ohm or 1 ohm on that sub. unfortunately, if you wire it in series for a 1 ohm load, your poor fosgate amp will fry (those models are piss). if you wire it series for a 4 ohm load, you'll only be getting about 200 watts of power out of the amp. those 10's need about 450 watts of clean power to move. you may want to look at a pair of single voice coil 8 ohm subs (see JL audio 10w08) or a dual voice coil 4 ohm sub (kicker 02s8L541). you'll then be able to present your amp with a 2 ohm load... which is still not good to do to those amps. as long as you put an in-line fuse on the amp, you shouldn't kill it.
