4 12s or 1 18?

yea well im thinkin it would be more of a hassle to do the 2 more 12s, is one 18 not very good? I was just thinking of sellin my 12s, buying a 18 inch BTL, Audioque HDC18, or a Re Audio SX18, now im not sure which would be the best between those 3, any opinions? well i was going to just keep the kicker sx amp to power the 18, build a new ported box, i was thinkin of a 37hz tune would that be good for a 18? and runnning it off the sx amp, till i have them money for a 3000 watt amp, like sundown or Audioque? what do you think

All those are very good subs, but the 4 12s would definately be louder as long as u built the right box dand powered them like u listed before.
