Bought a new box for my 99 FRC and it's setup for a 10". I've had a single 12" in my Grand Cherokee and it wasn't bad (Infinity Perfect), but it wasn't too loud. I'm looking for a little more volume out of this setup, but this is a 10. I used my old Rockford 800a2 to push the 12, and that's the same amp I'm going to use to push the new 10 in the vette. http://www.proboxrocks.com/chevy/corvette.shtml Can anyone recommend a sub that will be loud and well suited for the amp I'm using? I say "loud" because this car isn't quiet by any means. I'm not really into SQ, so I'd just like to feel a little "thump."
