So last summer I bought a 87 Mustang 5L Coupe (trunk not hatch) I getting around to putting a system in now and due to space or lack there of I'm kind of limited to 8" subs.

I don't know if I'm over thinking things, if I'm doing it wrong, or what, but I just can't seem to get the hang of figuring out a port. Normally I pay to have someone else design my boxes and then I'll build em, but my wife finally wanted a small enclosure in the back of her truck and since...
