ok, im new to this and its my first post so bare with me.

i have a California600 amp is rated at 450x1@4ohms. it is also 2 ohm stable if i need it to be. im looking to get a new sub to replace my old Lanzar 12's. theyre bottom end cheap subs i bought from a friend for a cheap fix. id like to get a single 13-15" that will out perform them. i was looking at JL audio 13W6v2. but i dont think my amp is powerful enough to run it. ill take any suggestions on subs. just looking for some advice! thanks
