You don't have enough space to do four 12's ported. You only have ~8.5ft^3 before sub and port displacement, which would probably work for three 12's.

Do you already have the subs? If so, what kind? Like d-REW said, SA12's or something like DC lvl2's would work well in a smaller box around 6.5ft^3 for all four. And you could still do a slot port as well.

Or you could do a single 18, it's up to you.

I already have 4 type r's .. ive been trying to sell them but the buyer backed out.. so im like what the hell I might as well try to put them in my trunk, The dude who sold them to me had them in a ported box tuned to 32 hz the box is 53 x 22 x 15.5 and its small but sounded good
