ive seen center mounted subs done in fiberglass, its like having a giant dildo inbetween the seats. mine will be done in fiberglass. not sure what else im going to do. the guy is really good, ill probably be molding a capacitor in there too. any other ideas that would be sweet? might do something with red neons or strobes back there...(may sound ricey, but what im picturing should turn out awesome)
