BTW, I got metered on Saturday. not on a new Termlab, it was some type of stand alone testing equipment, not hooked to a computer, dark grey with purple writing (don't remember the name) the shop owner assured me it was accurate but anyways I did hit 146.9 at the windshield.
I'm gonna try to track down someone with the new Termlab and get something accurate before changing my setup. Still I was pretty happy considering I'm only using about 1400 rms with just 3 ten's in the bigass Tahoe. Will probably change the amp before next test but not the subs and enclosure until I know what I'm hitting now.
