This is just silly. Everyone is making valid points though.
If the guys that have subs and what not were just a bit curteous, this never would happen. It's the same deal with cell phones in restaurants and movies. Have some common sense and turn the phones off or put 'em into silent mode.
Same thing. When you have some kickin' bass, and you're drivin' down a parkway or highway, no one is gonna say a word. When you're on a small suburban street, maybe put it a bit lower. Always lower it at stop lights and always turn it way down after like, 11PM.
Laws to ban these things are extreme.
