Well, it took a lot of testing for me to learn the truck and figure out how it got loud. I started "termlabing" the truck before I knew much about SPL, and continued to learn both on my own and with the help of TommyK. I will give credit to Tommy for giving me a lot of SPL information, but it was me who did the building and testing.
I feel that I can get better results out of a different truck than this one. Hopefully all of my equipment works, although my hu and amps are a little beat up. I don't know how much money I'll be getting from the case.
