I mean all dude had to do was just go “hey can you please turn it down a bit while you’re around the kids?”

Have you ever done something like this? Seriously, have you-- have you ever asked a couple men to stop being jerks in public on your own?

If a guy is blaring their speakers, they know other people don't like it, and they are basically daring you to do something about it, because jerks relish that whole experience.

I'm almost fifty, I have lived in many many places, including Brooklyn and Baltimore where this kind of interaction is common. . . and never have I seen this situation go as planned. Never.

Having social skills includes knowing this never fucking works bro.
