I've been looking around this part of the forum for a while now, and it seems like most of the people that help others out know alot about this stuff. I'm going to be upgrading my system in a couple months, but I'm not going cheap this time. I want to either run 2 12" Kicker L7's, or 2 13" JL Audio W7. In your opinion what would be the better choice? And what would be good amps to run with these? I beleive both are right around 1500 watts.
