yo, im going to be getting 1 RE 12XXX soon and I was wondering what amp will show the subs full potential, with the best quality. I have about $1000 and less for just the amp. Im thinking JL 1000/1, but some say that its just a bit shy of rms watts to show the full potential of the XXX. The other amps im looking at is the 2500D Orion 1Ch amp. Soundstream Tarantula 1Ch 2000watt amp. Or Ti1200 Phoenix Gold 1ch amp. Or any other amps. Also my stock alternator is 120amps, will i need a new alternator for 1 12XXX, one of these amps above, and a JL 300/4(for components) Thanks
