if you just want some loud...get 2 12" Alpine type r's and a used incriminator 20.1....should be able to score that for about 700 and it'll get very loud.
Already have pioneer fronts and front amp and hu. I have 0/1 for the big 3 ready to install, I have a 900cca battery up front, with 2 runs of 4 gauge. I'll replace that with 2 runs of 0/1 and add a kinetik or yellowtop in the back when I get the new stuff. Just looking for subs/amp for under 1k. So far I like the SX and the Mojo idea the best, I've already had type R's and they were pretty good just looking for something different. I was also thinking about 2 12" L7's and a suitable amp. would that be loud?
I don't have the money to buy anything yet. The IA 20.1 is sweet though. I like the cvx and 2607 idea. What would be louder on a 2607, the cvx's or the sx's? also are cvx's better than l7's?
