I am planning on ordering 4 12" , 3 15" or 2 18" OBSIDIAN subs in FOUR DAYS and not to sure which would be a better choice? Any other subwoofers i shouldlook at? What amp and enclosure for high output and pretty good SQ. Also if anyone has a amp that should push these perfectly PM me with price and details thanks. :) (And any more information i should be aware of will be appreciated)
