The kids these days with their low riders and tricked out Honda Accords. They're the main offenders, and then you have your average working Joe who shares the 2 bedroom apartment with 8 other people so he can afford to drive around with a system like he has something to prove.
That would be my guess.
I know exactly what you are talking about. There is a large group of kids that hang out at our local Dunkin Donuts and I could see one of them having these in the back of their car. It's very interesting that the lights glow to the beat of the bass. I wouldn't be caught dead with these in my ride!
And then because of all the aftermarket distractions, they have an accident and wind up in the hospital. Between that bill and raised insurance rate, they end up selling the car for scrap so they can pay the bills.
