Im getting my old 18"s back finally and I need a big box for em. Last time I did 14cu ft net with subs up and port back. the flex was crazy. Now i have twice as much power. I have to build the batts into the box now though so Ill have to find more airspace somewhere else. Should i keep the sub up/ port back combo or is there a better setup? I was thinking subs forward right behind the back seat headrests and port back..
