I've been out of the game for a bit so please excuse my ignorance if the technology has changed.....
If you are looking for louder then you want more db's for better spl. To do this you want more subs rather than bigger subs. If you are wanting more db's at the lower end of the audible spectrum then you want larger subs. Back in the day, a good pair of 8" could hit the lowest freq that is audible (20Hz) even though they were considered mid-bass drivers. For what you are looking for you may want to consider going with 4 good quality 8" or 3 good quality 10" subs to move more air, which would mean more db's and have a higher spl......which is what you are wanting, correct?
Again, remember it has been a while since I have been in the game, but I used to be pretty good at it
You could also get a program called Blaubox and input the specs of the drivers you are installing and what kind of box you want (ported, sealed, bandpass, etc...) and it will give you the dimensions that you will need to build it yourself. Used it all the time back then and it worked really good, there may be newer programs out there now-a-days though that are a little more user-friendly.
Cheers, and good luck!!
