Carnevil showtime cab wiring diagram?

[Arcade-Projects]

Hello,
I'm looking for the wiring diagram of the CarnEvil 39 inch /showcase cabinet. I want to know if that cabinet has an extra audio amp and how the subwoofer included at the bottom of the cabinet is wired.
I have been looking for the showcase version of the manual online, without any luck.
Thanks in advance!
