I've been loving BASS since the early 1990's at least. I have built a few 9My loudest was only 134.5 in 1996 and seen/felt a few awesome cars back in the day.
But my most intense BASS experience and most rememberable one would be just last year at the Tucson Bass Bash from Philip S.
And ironically it popped up in my memories on FB today, from a year ago. I was expecting an average150's type DEMO and got hit with a very strong 163-165 dB DEMO....It was awesome, after I regained my breath and my esophagus didn't collapse.
ENJOY: My first 160+ DEMO in the SUBFari Van
