Well I have some CVR 12s at the moment and one of them just blew so i am either gonna buy another one or go a different route with the subs. I'll be keeping the same amp (KX600.1) but i'm open to all options on subs. The CVRs are nice but not quite loud enough, i know i going to build another box so that does not matter. Price isn't really a big deal, I just want some new sub or subs with a warranty preferable. Working with around 4-5 cubes. Ideas?
