I need some help deciding on which subs to get. Depending on the load I got two amps I know I want. One is the T20001bd (my first choice) or two Alpine PDX 1.1000 (But that's second on my list). My gold is running 2000 RMS for a pair of twelves. I need some experience to guide me, because I have no way to hear them for my self. So I ask, for your opinions. I have three I picked from some recommendations, and I would like to know which is the best, which one would last longer, hit harder, and be a better investment. FI Q 12" 1000 watts rms SSA Icon 12" 1000 watts rms Alpine Type X 12" 1000 watts rms I'm getting a ported box & I listen to everything, but mostly boomy rap (Jeezy, Lil Jon...) But I want to hear all the notes, and have some good SQ, while at the same time have a loud hard hitting system (not SPL). Thanks.
