LAY on the horn and watch her launch a FULL Starbucks into the middle of the windshield as she wrenches the wheel due to the sonic terror. She learned something that day.....and so did her dashboard.
it might have been a resonance surface or your weighting was off.
they should be closer to 121db, 3db louder than the 118db a single set is rated at. still though, thats louder than the average rock concert (FOH mixes are done at 105db, front row will see anywhere from 110-115db from backline + stage noise).
Both can cause immediate hearing damage.
