box building sites and help??

[mark016]

i want to build a box behind a 87 silverado.The one i have is a bit to big and forced me to push the seat foward.
im thinking of putting 3 or 4 sundown sa8 v2 subs and have 7''x16''x58'' of space to work with and about 3.75 ft cubes.
would like an angled box something like 5 inches on the top and 7 on the bottom

would the 4 subs fit or should i put 3? and should it be sealed or ported?

From most of what Ive read the SA-8's perform better in a ported enclosure. Im kind of in same mind set you are I know 4 is awesome but 3 may be pushing space from what Ive read. Now take my opinion with what you will You maybe able to fit 4 but I think 2 SA-8v2 in a silverado would thump.

What about doing external aero ports to save some space? Put them in the middle of the box ports positioned between the driver and passanger seats, assuming the middle folds down.
