Okay, this is pretty much my first time building a speaker enclosure, let alone with fibreglass. I'll keep this thread updated as much as I can with progress pics. I have a '79 corvette, and the trunk area is extremely small. (35"x12"x14") of workable space. I opted to put one 10" sub along with 6.5" mids in the back. My budget isn't huge, so I went for a clarion 10" XW for now. The cabin in these vettes are extremely small, so I think this will be all I'll need.
Major of the box is MDF, and the front is going to be fibreglass to give it some curves. Then all painted gloss black, to match my car's exterior.
Begining of the box & fitting

Left to do:
-install terminal for the sub.
-using dowling, position and set the MDF rings
-fleece the front of it, then fibreglass
