Which of these two is better? I know they're both Kicker but I want the best for my subwoofer project.

L7, simply because its a better model.

I have a 10" L7 with kicker box in my tC... honestly, its more than enough.

better question is what amp do you have?

I haven't buy the amp yet. If I'm buying the Kicker Solobabric L7, I might just get the Kicker ZX amp as well. Or do you have any suggestions?

I'm planning to upgrade my audio this January. I'm changing all my front and rear speakers and my factory head unit as well.

Those subs need a lot of power! What ever you don't under power these, get a big amp.

any suggestions for the AMP?
