I am looking at buying an RE SX 12". I was then looking at the hifonics brutus TX1000D. it gives 1000rms. Would that amp work with that sub? is that a good choice for around $200? if not, what about the titan TX1500D?? which one should i get? or should I get a diff amp? or can anyone recommend a better sub for about the same price?? but mainly, will either of these amps work good.? please help thanx
