I like (in order of how much of each I listen to) Alternative rock, Reggae, and Rap. Should I go with 1 15" CV V-max or 1 12" JL 12w6v2. Your opinions on which one I should get? Also which amp should I get? A kicker kx400.1 or a JL e1400d? My HU has a sub out and the preamps are 2v.
I'd personally do the 12W6v2, excellent subwoofer. I'd say SPL would be pretty close, W6v2 may have an edge, but anyway, SQ def goes to the W6v2. Very well rounded sub. Both amps are great, and I'd say pretty much equivalent to each other in quality, in your case I'd choose mainly on price and features. Or you could just choose to match JL with JL for cosmetic reasons, anyway, can't go wrong with either. If you plan on a ported box, get the Kicker as it has a subsonic filter.
