I finally decided to stop fiddling about and just make a simple sealed box for the Alpine Type R 8" that has been sitting on the shelf for many months. I absolutely hate working with fiberglass but you just can't beat it when it comes to weight and fitting things into odd/tight spaces. This will be my 5th fiberglass car audio project, so hopefully there will be some benefit from the experience.

Got started today - on to the pics!



All masked off, used modeling clay to fill voids or round off sharp bends.



Got the glass layed up...



Here it is popped out. God I hate fiberglass.

Tomorrow I'll trim it up, make the baffle, and hopefully glass up the rest of it.
