I just traded my 2 18" Audioque HDC3 18s for 2 12" T3 audio T2000's. I got a 2009 Buick Lucerne,I got 2 options really, I could go subs/port back with a slot port, but the guy I got them from was saying I should fire the Subs up port back suv style with 4 6inch aero's with 8 inch flares. What do you think the better setup would be. Back seats don't fold down,It does have a rear center console hole from trunk to cabin, and the rear deck 6x9s are going to be taken out so I can get some more some more air passing into the cabin. What are the pro's and cons. Also what should they be tuned to?I got room for about 7 cubes gross. How much port per cube do these things like I know audioques like 20sq inchs per cube?I'm looking for a somewhat flat frequency response and I'm trying to be able to play from 30hz-68hz. I probally could fit subs/port back but only 2ith 2 6 inches aero. Also I seen someone go Subs back Port to the side as in one to the left side and one to the right side
