I purchased a "Outlaw" pachislo slot machine yesterday from "Craigslist". There is 2 speakers at the top. I'm not sure if there is one at the buttom. It's hard to tell. If there is a wire that is going from that buttom door to the switch box, would that be the speaker wire because im going to install a volume control for it since it's loud. Does anybody know much about this slot machine? Thanks! :-)
