So, I heard Buck's system today. I've never heard a system that loud, and I'm 31. I could barely breathe in that thing lol. When I was 19, it was RARE for someone my age to have something much louder than 2 12s on like a 500 watt bridged 2 channel amp. Class D monoblocks were rarely used by regular car audio hobbyists back then. Same with > 14 mm or so Xmax subs. Most were like 6 - 10 mm Xmax. I wish I would have kept my old Phoenix Gold amp from my only install back in the day. Didn't get back into audio whatsoever until 2 years ago when I stumbled into Cartronics looking for 6x9 boxes lol
