Stick with the JL 12W6's. Yes we sell them so yes I am biased. BUT, we also sold Kicker for YEARS and I cannot even give the few I have left here away at cost (see our ad in our shop forum) because when people come in and compare the subs firsthand on the display board, they ALWAYS pick the JL's. Or, just use one 13W7 and call it a day. It will knock louder than any combo mentioned here-louder SPL and cleaner SQL-any installer here who has installed these in the past will agree. Again, as long as it is in your budget anyway. If not, my second would be the 12W6's.
