ok, for my new system, i've already choosen the CDA-7995, but that's as far as i've gotten. for subs, i think i've limited it to 2 E12K4's, 2 12" shiva's, 2 RE SE's, 1 12" X-Treme II, or 2 Shocker III's. i know this is probably a lot to ask, but i have no access to any of these without buying them first, so i'm going to have to trust your judgement. bascially, my goals are (1) it has to hit at least 140db's, (2) sound decent while doing it, and (3) sound really good at low levels. if you can rate these in a specific order, or just tell me which one's are better for what (SQ, SQL, SPL) that would be great. Thanks in advance.
