Without knowing what mic and more details about the actual install (and how it was metered) - it's impossible to really comment.The trophies would seem to indicate he's a competitor in some organization - but again, without more info - would be hard to accurately criticize.
I think it 'would' be safe to say it didn't do a 158 on the dash with TermLab though...
Hell, I've done a 162 in the kick with 3 10s and ~2000 watts on the old AudioControl. There's several variables there, how was the K-Factor set? When was the last calibration? Etc.... etc....
