Heyy, atm i am looking at buy two subs and two amps, so i can power 6x9's as well.

im looking for subs that pack a punch but have good quality sound, iv been offerd some inphases but dont no if they will be that good.

What would youu say would be best sub for bass and amp to power it, cause i got no idea don't mind going second hand either.
