so now that I've had a couple days with them iam happy to say that these subs are phenomenal, great response great power handling(rated 400 rms but I run them at both 500 and 600 and not even a noticable twitch in response or output and no distortion.) I would rate these easily higher than JBL's and up there with kickers. these subs room ck. if you can snag them I suggest it. retail price is a little high. but again if you can snag a discount ide warrant the purchas!! ill have vids up as soon as I can figure out how to transfer from the phone.
