i was looking at a old post and came apon a good question for either of you guy's.so i should run the us amps at a 4omz load for 4 15 re x.x.x. for a better sound and overall performance? so what series would you the exterminator ab series?your input would be most helpful thanks.
well the triple X comes standard as a dual 2 ohm coil sub, so you'd get a 1 or 4 ohm load from each sub. if you choose to run the sub at 4 ohms then you'd need an amp that can deliver about 1000-1500wRMS @ 4 ohms for each of the subs. you may be better off finding an amp that can deliver about 2000-3000 watts @ 2 ohms, and running two of the RE subs on the amp @ a 2 ohm load so each sub gets half that power.
the biggest problem you're going to run into is supplying enough current to feed over 4000 watts of amplification for those 4 subs. that's well over 400 amperes of current just for the sub amps. that's not even counting what the car itself needs, or any other amps you use for mids/highs.
