I heard the loudest system at glamis a month ago that I have ever heard. I was listening to sublime and hearing the mids tweets and Bass from like 1/8th or more miles away. It was echoing off all the trailers in the area. It needed some TA and imaging to sound ood from where I was listening lol. Whatever the hell that dude was running he was probably using a Friggin Generator to run it, I'm not sure if it was in his Truck or Toy Hauler but probably BOTH, I don't think dual alts would have cut it....
It was interesting but WTF would I do with a system like that I don't know. They got a ticket for noise polution and this was at friggin glamis with all these **** 4 strokes and dune buggies with extreamly loud exhausts driving around all night long...
