I was watching a TV show called "Rides" one time and they made a car sub enclosure out of the special wood, with a fiberglass base for the speakers to sit on. I think it would be neat to make one that is curved from the fiberglass... following the right ammount of layers and all that, would it be strong enough after the volume is turned up a lot? or would the fiberglass break? I have no fibreglass experiecn, and I saw this, so I was just wondeering. Also, how does the fiberglass effect the sound quality? Thanks!
