I've been reading this forum for a few days and I've noticed everybody seems to be quite helpful. I just purchased my Titan in October and am just saving up the money now for the system. I have two JL 12W3s and a Total Mobile Audio 500.1 amp that came out of my Tahoe. I'm curious as to your opinions on whether to stick with these JLs or try something new? And suggestions on which types of subs? I'm going to purchase the box from Tech as soon as I figure out which kind of subs to purchase or if I should stick with my JLs. Thanks!
