So I have spent some time fooling with winisd and torres and have come up with 2 4th order designs that will fit in my space(03 subaru outback)
I have read in a couple places that box 1 has some issue with the port being aligned with the sealed chambers, and that the best design is to have the subs in separate sealed chambers in the back of the enclosure, much like box 2. Anyone care to confirm or deny this? I would prefer to use the 1st design just because it will tend to be louder ported back rather than to the side like box 2 does.
This is also my first 4th order build so if I am making any mistakes feel free to jump in a point them out. Box is for 2 rival 15", (similar to dc level 3s) on an alpine mrp2k
