Had a few people asking me about how I built my roof so I figured I would post up a few pics of this one I just finished for a commander that holds 8-6.5"speakers and a 10"sub. Starts off in three seperate boards because of the angles of cage and then glassed together. This is MDF board and felt with fiberglass resin and then bed liner. Very sturdy and get alot of people asking where to buy them. By the way I do not build these to sell. Sorry this was for a buddy of mine.
