fiberglassin

[west nile]

i am planning on fiberglassing my rear 6x9 lid(00 honda civic), I am new to fiberglassing, and I just need info on how i should go about this. I plan on cutting out the mdf 6x9 templates and gluing them down with dowels and positioning them toward the front of the cabin. I know i have to first lay down plastic, then tin foil and a couple layers of fiberglass resin, but how will i mount it? do i add some fiberglass tabs to hold it down? or should i make some fiberglass tabs to mount it with screws? or should I just screw into the rear hatch through the bottom of the base?
Also should I make a hole through the base to run my wires to the amp?
Should I use a grill cloth for this project or fiberglass matte?
I know that is a lot, but I would appreciate any feedback from anyone who knows fiberglass.
Thanks
