Having owned nothing but Kickers my entire audio life for my own personal rides I will say there's just no comparision at all here. JL is by far a better product in almost every aspect when it comes to subs. Kickers are just extreamly cheap compared to others in it's class. I consider Kickers the best bang for the buck because they sound quite nice and are so dirt cheap comparitvely it's ridiculous. However if you want quality and deep bass JL is really in a league of it's own. However if it's SQ you're after over SPL I really like the Boston and MB's over the rest. The Infinity perfects have decent SQ as well. It really comes down to you're listening preference how deep your wallet is and what application you're going for.
