no not really, you will have to wire it out of phase also you will not need to subtract the displacement of the woofer from the net volume of the enclosure.

by out of phase do u mean switching + and - around

SSA has a couple free enclosure designs: link

If one of those don't work for your vehicle then you can get one through the ssa store.

The designs are made / approved by SSA after all, so yes they would be optimal

You don't have to wire it out of phase, wire it how it sounds best.

You could also experience some mechanical noise from the moving parts as they wont be masked from being in the enclosure.
