Right now someone figured out my box was 3.8 cubes at 31hz after disp. With that, a 15" BTL with no options and a Hifonics BXi2006D I hit a 141.7. That was my best score. I am getting alot of different inputs on box sizes to use...and I know hitting a certain score has MANY varibles...but I figured to start off..a better box could help a good bit. It is in an extended cab truck, port up and sub up. I want pretty much SPL, but it is my DD. With a new box, I am still going to be listening to music.
