god I hate people that do that.....We call it Cruzzin in the states. They have hard ganster rap blasting ...booooommmm booooommmmmm...yah here them from down the street. Funny i use to run with 4 AMPs, 2 6'9, 2, mids, and 2 tweets pumping 2 kicker comp 15' woofers and I would just relax and listen to my music. The a "wanna be ganster" white boy would come up cruzzin with his crap loud. I would laugh at him and turn my s*** up. Always made him feel like s***.
