That box should be about perfect for it. If it isn't brand new find an amp that can put out about 2k rms and run that sub at about 1200 rms with 0db for clean power. Dont mess with the dubbing if you go over 750 though because if you clip you'll kill it.i m looking into putting a kicker cvx 12 in a 3.0 box tuned @35 with 1000 watts? has any one heard or used a cvx 12 in a larger vented box? would it get loud and still sound good?
