I've got 2 audiomobile EVO-R 12's running off a US AMPS exterminator 400x which is pushing out 750x2. Currently I've got them in separate sealed boxes slightly larger than 1 cubic ft. for each.
I want to build a vented eclosure that both subs will go in. I want to make a box with both subs on the face and the vent one side or the other of the two subs, but on the same faceplate.
I figure with the space in the trunk I'm working with, I can have a box with internal volume of 5cubic feet max, and can get as small as 3.5 cubic feet. Can anyone help me with port dimensions (rectangle port) and how big or small I should make the volume?. Any help would be much appreciated as tech support from audiomobile in nill cause they went out of business.
