Next,
I've got some work done on the front door speaker pods.
Step 1, make the template form out of 3/4" MDF.

Step 2, make copies of the above form with my POS Home Depot router table and some flush trim bits.
Step 3, attach them to a backing plate with some wedges and hot glue. (sorry, no pix)
Step 4, get some fleece, two-way stretch, or preferably four-way stretch fabric and stretch it over the form so there are no wrinkes (no wrinkes on the front, you can have as many wrinkles on the back as you want!). You can staple it on the back as shown.
You'll end up up with a very organic looking flowing form as seen below after step 5.

Step 5, fiberglass resin.

This would be a lot smoother but my old resin decided to set too quickly and get a little thick....

Step 6, trim excess fabric.

Step 7, admire your -still as not yet completed- speaker pods.
I have a little sanding to do and I may reinforce them with actual fiberglass on the inside later. The general idea though is to cover them with vinyl when they are sufficiently smooth. I think they'll turn out really well and should look like they are made for the car.....afterall, they are.
