Call RE and ask the guys there that own XXX's how they run them. So far Ive found 2 guys that run them sealed (for the SQ), and 0 who run them ported. I think they sound excellent sealed also, so I dont know where this notion they don't perform well sealed came from. Aagin if you don't believe me, calll RE and ask those guys. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
I recall someone putting a XXX (although might have been a 12) in a 350Z a while back. Pretty sure it was on this board, he was asking questions about moving the t-top rack to mount the box.... or something.... iirc.
