I am looking for something like 4 sa-12's, nightshade subs, dc audio 12, 15, or 18's, fi btl's or something like these. I was going to downsize so I took my fi bl 18's out and sold my sundown 1500d's. Well I ended up buyin a sundown 3500d and have it on pair of audioque hdc3 12's now. I want to trade 2 FI Bl 18's and 2 aq hdc3 12's for other sub setups. let me know what you have, i have several pics of subs. Would like to do it locally or meet up, rather not ship
