Zane, Mark ab, myself included. You can only say so much. Until they grow up, they won't realize what they are doing. I thought it was cool, to go around bumping when i was in my teens. I thought it was so cool, I went bumping through a church building, the first time I was told to turn it down, so I went through there again with it cranked, this time they tried to stop me. So being a dumb @ss I went in through the back way cranking it up once again, this time a guy got his hand in the window and hit a friend in the head, I floored the car and the guy ended up breaking his elbow. So yeah I thought I made quite an impression, boy I was talking about it for a week and so were friends of mine and other people. That was until I wrecked my car two weeks later. I pulled right out in front of a car. I looked both ways, twice, and did not see a car, still to this day I believe I was reprimanded for my behavior in the church parking lot. I have been tortured by installing friends systems and not being able to afford one for myself for almost 2 years. Finally, with the help of my brother, we both pitched in and I got bump in my car. I also learned that I had grown up, and now I respect other people's privacy.
So the point is: maturity brings respect, and until they mature they won't have the sense to respect other people's rights. If stricter laws on noise violations are implemented, so be it, they will be the ones paying the hefty fines.
