I've gotta say i don't usually shy away from loud things.
I'm usually up the front for festivals and the likes because it's loud and i'm with my mates. At times i've thought, f**k this is loud and went to the bar to get a couple drinks and chill away from the speakers but other than that i'm always pretty much at the front.
With car audio, my stereo is stock standard but still reaches a pretty reasonable level. That being said, yeah i play my music loud and i listen to all varieties of music which do include a lot of doof doof but i keep it reasonable when needed. For example, suburban areas, red lights, gridlock traffic, parking lots or when i need to concentrate like in heavy rain or nearing construction sites etc etc. More or less anywhere where i am in direct sight of the public so i'm not labelled as a douchebag. Every now and then though it's funny to make the people next to you put their windows up due to your music when they've been giving you the shits previously.
