Lol you do that William. Be sure to take a mic with you and post the results on here when you get finished. Im sure everyone will want to know those numbers.
The 194 limit is only referring to sea level, anywhere below sea level will have higher capabilities due to denser air. Underwater acoustics are a horse of a different color, underwater volcanoes sometimes get louder than 270db underwater.
I believe I mentioned all of this about submersed sound pressures earlier didn't I?
Anyway we're talking about car audio systems here so underwater measurements are a bit out of context.
