I've got a 3512d which is my in my car right now being powered by a sundown saz-1500d and I got a 3500d series motor that I want to trade for a 9512 or 10, AQ hd3 12 or 10, btl, apx, or anything other sub that can hit 40's in a trunk car. I'm looking for dual 2, 1.5, or 1 but if the trade is right i'll take a dual 4 and recone it. Shoot me offers
