FYI, the Spring Break Nationals car stereo show and competition is from April 1 - 3 in Daytona. More info HERE.
If you've never been, you must go. I've been there 14 of the last 15 years. You'll see some of the wildest sound systems around. Many are company sponsored, so money is no object. I always go on Saturday and usually stay the night, then go back on Sunday.
Just thought I'd share for those who haven't been/heard of it.
