I heard the Kicker van in Tulsa Oklahoma a few years back, would have been about 1999-2000, heard the thing booming from inside a mall half a mile away!
Loudest system I have heard in person sad to say, is mine. It's only 2 12" CVRs with about 1200 rms, ported@30 hz. Got an epicenter on it and running a very clean signal, it does sound like a couple monster 15's though, people stop and unashamedly stare when I go by. It's louder than my local Memphis dealers show car. Just wish I could hear some nice setups locally //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif
