I won a nice coin door off ebay for 20 bucks, I am happy

I have a quick question though. The coin door has 2 slots, but I have a 4 player machine. Is their any way to hook this up, or am I better off hooking up 1 slot to player 1, 1 slot to player 2, and leaving the third and fourth player with standard buttons to insert a coin? Thanks guys.
