Assholes.

The only reason for having a subwoofer in a car is to be a prick. It has absolutely NOTHING to do with "music appreciation". It's SOLELY to be a prick.

Communities need to have one or two cops whose only job is noise enforcement (loud cars, loud parties, loud yelling/shouting, loud stereos), and the tickets/fines for noise violations should be utterly ludicrous in comparison to other fines, since it's such a total violation of other peoples' quality of life.

And they really should make it illegal to have subwoofers in vehicles - illegal to make, to buy, or to install.
