Not sure if you're joking or being an ass, but if I'm not sure than think of how thw new members feel... And wait, didn't you do an intro thread.. http://www.ohio-riders.com/showthread.php?t=31260 What if nobody welcomed you??
Cool stuff man. I'm currently running 1 Kicker L7 15 in a (just under) 4 cubic foot box tuned at 30hz, which is being pushed by a Kicker ZX750.1 in my Cherokee. My SPL meter only goes up to 130db and I hit that at less than 3/4 volume.
I think they added it on their sportbikes even sooner IIRC. I had a couple ZX6Rs and a ZX9 that all had it. I'm sure that's all the issue was since it was fine once on the street.
