Thanks guys!
I bought 1 gallon of resin, 2 sheets each of 3'X3' fiberglass cloth and mat from Home Depot. A lot of cheap brushes. that's about it. I already had masking tape to line the spare wheel with. Used left over plywood for baffle though MDF would have been better.
I still have to finish it up but I test drove it in the FX with a cheap radio shack amp. (surprisingly it works with the balance signal but I had to keep the gain at minimum) and its a BIG difference from the stock sub. I've ordered a Xtant amp which accepts balanced line inputs.
Amp will be mounted on one of the flaps behind the rear seats. Once it is all done, I'll put up more pics and details.
