The 12W6v2 is an excellent sub and you wont be dissapointed with it. It can also get pretty loud. There aren't too many subs out there that have as good or even better SQ than the W6v2.Come on, guys I'm serious. I want something that sounds good. I'm thinking about something like a JL 12W6v2 or a Brahma. Are these any good? Anything better? If I wanted something to just fill the hole in my enclosure I'd stick in an MTX or a Kicker.
