First FG project for subwoofer box

I am building a subwoofer box for my Bronco.  The box will be on the trunk so I took the space needed for best SPL (3.2 cuft). Everything here I learned from different forums information. I started the project about two weeks ago but now I just have one day a week to keep working.

Any suggestions, just let me know. Enjoy!

This is the interior after "cleaning up" the seats and carpet.

The form of the box with the back hole that should be later mold with the trunk shape.

As you can see, I didn't have a router, I did the rings manually with a jigsaw (a real pain in the ass)

The fleece step.

After several layers (about 6)

That's the port. There is two of them

The Skull I will use for the lower port

 Checking if the sub fit

I made the mold on the back and place the box in the trunk.

Next week I look foward to update my work.  Put bodyfiller on it and start sanding ("the best part")
