for the 15" x.x.x. sub, what would make it sound better and hit harder, the hifonics 1800D or orion 1200D. i bought the 1200D but i was just wondering how that hifonics amp compaired to it. i know it puts out more watts but i havent really heard good things about hifonics amps.
I think that the orion would make it sound better because it has better wuality bass produced. It might get louder with the bx1800d, but people on this site have said that it produces "choppy" bass.
