Good subs for my car? good price?

Personaly I have 2 12inch kicker comp cvrs, With a 1200 watt 1ohm stable amp from rockford fosgate. I have frieds who have 2 15's and cant get thier systems to sound and perform near what mine does. I have them in a ported box tuned to 32hz. So they move Alot of air and will play deep and some higher pitched bass. Personally if you can afford this set up and its in your range this is what i would put in your 2011 GTI. It's a small cabin there for with the right box its going to move alot of air and will deffinatly turn heads. It's more than plent of bass. As far as the 12 inch Kicker Comp CVRs go they're pretty responsive i listen to everything from country, rock, metal, dubstep, techno, rap ect.. so they'll play your double bass and if your long deep bass with music like young jeezy for example. So i hope this is the kind of answer you were looking for=) if you have any questions to be scarred to ask=)
