I think you use nails or some type of screws to attach the fiberglass to the mdf. Mine also has mdf on the sides to reinforce it. It sounds decent, but I don't think mine is completely sealed so it can sound better. But my friends that are into car audio with really nice systems, say mine sounds like a typical decent system (i have cheap amp and subs).
