More performance

I was thinking about upgrading my system, but then I thought I might be able to make my current system louder. I have 2 Infinity Perfect 12's powered by an Infinity amp (300x2). I am not satisfied with how it sounds outside the car, as in it's not loud enough. I believe the sealed box I have is a little bit too big (1.33 cubic I believe). Any ideas on how to make it louder still? Thanks
