I have a question about the meters that the different orginizations use. I have always been told they are only accurate to 175 db. With scores, especially in extreme and outlaw getting so close to that(and by some results I have read past that) how confident can competitors be their score is accurate if it is very close to 175db?? LIVE LOUD!!!!!!!!

8 jl 12w3's
4 crossfire 1000d's
172.8 extreme
166.5 outlaw
stock interior and no shell

As confident as anyone could be about anything? How confident would you be that your doing 160 in a Viper with a speedometer that has been calibrated to 160?

If it dont fit, force it... if it breaks, it needed to be replaced anyway...

Well going on that I have seen a AC meter read as high as 196.6. When we were playing with it. Was that accurate..Hell no. Also I have never seen a legit number for SPL go over 175.

Thats what I was saying... if you see a number higher than the meter is calibrated for, it's total BS, but if it's within the calibration, it's pretty much legit. Spiking a mic will generally show the highest reading a meter can physically show.
