My first score was a 39.9 on the TL with my 15" MT.
Box has a LOT to do with it, my box was terrible, and the CD I was playing was scratched. Plus my amp rolled into protect for some reason, so I had to use only 1 RCA and run it mono instead of both RCA's (stereo). That didn't effect anything, but it looks prettier with both RCA's in my opinion //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif.
Box makes a HUGE difference, make sure your not using a crappy box next time you get metered and it may change a lot.
