Lol, I've heard L5s get so loud. My friend had 2 12" L5s off a kx1200.1 in some nice box that must've been tuned to like 40hz or or something, I could feel it in my chest like none other. Rattled the crap out of his little accord. hit up the L5s, but tune them a little lower for some SQ, his setup was insanely loud but lacked in SQ (they were the 2004 L5s too, the 06s are probably much better)
