I would highly reccamend NOT using fleece for the whole thing!
fleece will be good for the first layer to stretch out the shape that you want, but the resin will not soak through the fleece like it will with fiberglass matting and woven fiberglass.
make the shape you want with wood, 1/2" or 3/4" mdf in areas that you will not be fiberglassing over.
make a mounting plate for the subs and cut some pieces of wood to support them in the shape that you want them to sit in.
stretch some fleece over the frame you made and resin the top of it, then go over it with matting and dab out all the air bubbles with the paint brush.
do a few layers of matting then a few of the woven fiberglass, the first layer with the thicker woven and the last layers with the lighter woven to give it a smoother finish.
try to do this all at once to make it all one primary bond which will be stronger than secondary bonds; doing a layer and letting it dry then another layer and letting it dry etc . . .
too much resin insn't a good thing, it adds unecessary weight and it's the fiberglass matting and woven that gives it the strength.
good luck
