RF punch xlc Box size?

I bought a 89 supra a while back and the previous owner had 2  8" punch xlc rfp 2808 subs in seperate ported truck boxesmade by kicker with tweets. They arent x-overed and the boxes I think are too big.I took them out immediately and replaced the whhole system and the xlc's have been sitting ever since. Now I think I want to put them in a new box that is the right size. Does anyone know the recommended box volume? Rockford Fosgate removed their archive section and i was unable to find any specs there. Thanks

ported or sealed????????  i think its .75 for sealed and 1.25 for ported  1974 ford pinto 4 15" punch Z power punch bd 1001 pioneer DEH-6700

I haven't really decided yet whether to go ported or sealed, I'll probably go sealed but I'll take both volumes if you know them. Thanks
