well 1200 watts and a pack of marlboro menthol lights a day hasnt killed me yet, and i know there are some people pushing 3k + with the same habits or worse who arent dead. I have heard that it can cause old people's (no offense to anyone) hearts to stop but never puncturing a hole in your lung... thats crazy.maybe 'researchers' are trying to scare people into making car audio a lower priority for the police forces of the world. hm......... like the old people can hear 'em anyways after they have taken their sleeping pills and they are k.o.'ed.... lol..... dam i am rambling away and i know this stuff made absolutely no sense.
