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?
