How many cubic feet?
-
i know u asked that a while ago. but the rule of thumb for aero ports are 8 sq in of port per cubic foot. so if u got 2 15's u need at least 6 cubes after displacement. well the formula for aeros is radius squared , multiplied by 3.14 ... so 5" port would be 19.6 sq in.. u need 48 for 6 cubes so 5 5" would be more tha enough.. make sense?>

wow i wanna know how the hell you fit 2 18's in there? box dimensions and port dimensions i want details dude thats insane to put 2 18's in a trunk. 1 18 would be huge in a trunk!

you could probably get away with 3 4" ports if that's all you can fit, but you should still go bigger

you think 3 4'' ports would be good for 2 15s?

depends what subs...but I'd try to do more like 2 6" ports or more (equivalent of 4 4" ones)

thats 4'' ports ?

They're 6" ones, which is still holding it back in terms of output...it really needs more like double or triple this much port area...
