I would choose from either Alpine type R or the L7, any way do go for the Hifonics they don't have the same quality as the Alpine and Kicker, Since the L7 is refurbished, I would get the Alpine R. People often blown the refurbished subs out, and the company said is not their fault, because they hooked up wrong all that, so freaking bull crap. Unless, you don't really care about it. Also for the L7 they are more of spl then sq, Alpine your getting a better sq then the kickers, really I would choose between those 2, I used to have alpine type R, they are loud, and replaced them with kicker CVX's they are loud and a lot of bass, not very clear. If you want spl go with L7, want sq go with alpine.
