Those Atomic subs are insane, I would say the Cactus MK2 possibly, Treo CSX, or Treo CXT, DD 99 series, DDZ easily. Oh and yeah quad coils are sick. My friend needed one for his Memphis Mojo that the surround shredded itself and the only had an old quad 1 that worked and you can tell it takes power easily and gets louder than the new mojo dual 2 they have.
