One of my buddies here in NC just set a new world record two(?) weeks ago in the biggest pro class there is. Same deal as described in the article. He gets all gear free, and like 30+ batteries. It's crazy.
I dont understand the desire for this either. There cars are tuned to play tone's not music 70 HZ for 3 second blurb's and thats it it's over go home. They dont even have mids or tweets in there cars I think the things they learn in this hobby transfer into real stereo stuff that you and I use. Just like in F-1 and Drag racing some of the tec makes it into our car's
I don't quite understand the desire either, but I am sure that there are millions out there that don't understand why we wreck our bodies and spends 50K on wakeboarding which normally can only be done part of the year.
