I have been looking at the Loaded SSA Icon, the Fi Bl, SI Mag, and a couple other subs but cannot decide on a size. I want to keep most of my cargo are in my Durango, but want to ensure that my sub will get plenty loud. Will a single 12 with 1,200-1,600 watts be up to the task of getting loud or should I sacrifice a little more room and go with a 15? Also, I would like to be able to run sealed if possible but ported will be fine, retain some SQ, while feeling it in my chest, if possible. Any help would be great.
