Well after many failed tries i cant seem to get as loud as i think i should be. (and others) Even though i think my new box turned out kick ass, it seems it may be aiding in my low numbers. I got a SPL bass meter a few weeks ago and my best is only a 137 @ 38 burp and 135 on music. I have swapped every component out one at a time expept the box. looks like its time for a new box re re re re re re re re rebuild.
