sub box question

[XxslayerxX]

i want to make a custom sub box that holds 2 10" subwoofers behind my car seats. I have a honda del sol, so i removed the back interior piece. So my question is how do i start making this box. Should i make a frame out of wood and wrap it with fiberglass to make a box for each sub and then connect all of it with fiber glass to make it look like one, or try to make one whole box for both of them?
