Powerbass 2k or 3k watts

[MASTER T KILLA]

I just got two Powerbass 3xl 12 inch subs and im currently running them off a 1500 watt Crunch Powerzone amp and im looking to upgrade to a Powerbass amp and i was wondering if i should just go with a 2,000 watt amp or just go ahead and get the 3,000 watter? either way would 1 do the job of collapsing lungs or should i get 2 and hook one to each subs so i can remove concrete with my car? Thanks for any and all info

Thats actually one of the ones my dealer was showing me when i picked the subs up. looks like that just may be the one i get thank you
