Got a start on the box today looks like I will have just enough room for all the fiberglass panels. Amps will go in the back. Batteries will be mounted under the box. The fusing will be built into the fiberglass panel by the rear passenger door. (for some reason I can't hit enter to space down to the next line so pics In next post)

I had to make the port big enough so I could crawl in and hook the wires up.

It's 5 ply Baltic birch. I buy it from a wholesaler. It's not the cheap shit homedepot sells.

spent a few hours looking into how I will be attaching fiberglass laminates to the cars body panel. I'll put up a few photos of the process when I tackle that. I did spend a few minutes finish cutting the wood for the box and did a little assembling.

The body panels on these cars are pretty thin so I'm going to laminate fiberglass panels to the inside of the car. For the roof there will be a total of 5 layers of 6 ounce E glass and 4 layers of 1.5 ounce chopped mat with ribbed supports. This will be done in stages to prevent warping from heat.

After taping off the top of the car I marked down the factory body seams with black marker. The marker will absorb into the resin and provide a trim line when I remove the finished laminate.

I only do three layers at a time to keep heat down

I needed a tad more resin to get complete wet out. I didn't roll on quite enough on the table but this is why I always wet my mat out upside down so that when I lay it right side up onto my "mold" I can add more to completely wet out any mat that's still dry.

It's not perfect but I guess it's not bad for my first layup in 6 years

Nice job! I've never seen this method used before. Can't wait to see the results. Will you be able to add any deadner to it? Or is this the only acoustic enhancements you will be making?
