ok so i'm looking to try my hand at at 4th order... in all i want to make one for 4 12s but i want it all to stay in the trunk, i have about 10 cubes total to work with, the external dimensions are 36W X 17H X 30D can go alittle dee[er but it'll be very tight to fit an amp in there somewhere. how big should i make the sealed chamber and the ported chamber? i want to make it to bassrace 39.9 maybe 49.9 if i can get it that loud.

sealed or common chamber

ear drums are very over rated

so like 4 cubes for the sealed chamber then it'd only be like 5-6 for the ported one depending on the thickness of the walls

single 15"bandpass, sounds about right.
as for the four 12"s, your probably better going ported with that kind of airspace...unless your subs EBP is around 30 or less
