got a good start tonight. i had the rings and the outer framework already done, so that helped a lot. here are pics:
framework (note: these pics are after the first round of sanding. i spent about another hour making all external edges really round and smooth but forgot to take pipcs of them. see the pic below with the ring mounted)

here are the rings. took a drill bit and made some holes for the dowels to sit in to make mounting easier.
a few dabs of hotglue in each hole and a thin bead around the edge and 5 mins later and the dowels were set for life
dowels were cut to length, then hot glued and brad nailed into place to support the mounting ring
rings and dowels mounted and ready to be covered
the supplies
boxes covered in polyesther and ready to be coated with resin
this is sort of how it will look once in the trunk. i have the fold down rear seat which i still want to be able to take advantage of, so each box will sit in the back corners of the trunk with the middle area open. the amp will be suspended between the 2 from the rear deck lid giving me plenty of access to slide things through if the need should ever arise.
coated with resin and drying overnight. this weekend i will lay down a few layer of fiberglass cloth to strengthen it up as well as more filler inside where the ring meets the cloth.
my original intention was to do some presanding and then take it to my body guy to have him to the bondo to a smooth finish and paint, but i think i am going to have them covered in vinyl. it will save me TONS and TONS of sanding time and still have a very nice look to it. plus, due to some of the extreme bends and curves i wanted to make i had to overlap some of the ploy cloth to get it the way i wanted. with a vinyl cover that will go un-noticed once complete.
