well yea anything cost mony. but you could build a full fiberglass enclosure yourself for about the same price shops like auto audo and ave would charge for a simple mdf box with a trim panel. but hey i usually have suplys sitin around that im always willing to help out somone(because i have alot of time on my hands) dalton knows first hand cuz i gave him a can of resin and fiberglass mat i had layin around. alls im sayin is truly custom work if so expensive because of truly expensive time and labor charges
