Kicker CVR 12 or JL Audio 10w7?

Im buying a Trans am between the year1998-2002. I had a set up of 2 12CVR Kickers in a 2000 Trans am before and sounded great. Im looking to see whats better in sound and deep bass. So would a JL Audio 10w7 x1 be better then my two 12 kickers? Cost is not to bad for me right now. Im just trying to get some real good input on if I should go buy one or two 10w7's. I still have the Kickers. Im having a custom box made right now. So when i get my answer I will have the box made for what ever speakers I decide to toss in. So please anyone with some real good input. Also trying to figure out my Amp thing too.
