In this case, go with four 4ohm subs. Two parallel on each channel.
.....yes, Zumbo, if, as Mac said, the amp is solidly 2 ohm stable....you would get punch and accent and pop with the 2 ohm wiring demanding 2 ohm bullets....or....you could wire two speaker elements in each box of two, for two subs in the front, in series, and get a smoother, sweeter, more legato response which is very good also....but....BARRACUDA1968, I graduated high school in 1967, and I'm tellin' ya', you would probably want parallel wiring for both sub enclosures, two elements each, for a total of four in the act up front....if your amp won't handle 2 ohm stable, put a small plastic fan from Wal-Mart on the amp on low, just blowing over the top, you won't hear it....if that don't work, either move up with another amp, or pull a woofer out of both cabinets and rewire the two in each box in series......
.....to wire the two elements in series inside the enclosure....a seperate, short, speaker wire, probably about two feet long for hooking-up length, might as well use 12 ga., stripped on both ends a half inch, is needed....hook up the short wire from element "1's" minus (-), to element "2's" plus (+)....you're done....then, the "incoming" plus (+) wire, goes to element "1's" plus (+), and the "incoming" minus (-) wire, goes to element "2's" minus (-).....
.....to wire the two elements in parallel inside the enclosure....twooooo, short sections of speaker wire a couple of feet long, stripped at both ends, start the show....hook up one of the two wires connecting the pluses of the two speaker elements, and the other one connecting the minuses....bring the incoming plus and minus wires to either speaker element, and hook up as normal, plus-to-plus, minus-to-minus, thank you....bow....(exit stage left).....
