hey guys whats up, havent been on here in a while! good to be back anyways, i was thinking of trying out the new Shocker SS subs. I was looking at putting two of the 15s into a large ported box, giving each sub about 600 watts. Do you think this setup would be able to produce good SPL? Are they worth trying out (only $150 for the pair). let me know if you think they have any potential. thanks, corey
