From Jamma connector wires do you connect the two wires to the two connectors on the arcade speaker?. I am still getting buzzing changed speaker for new one and also changed to AT Power supply.

Bender:
how bad is the buzz?
These boards have notoriously crappy sound

CheffoJeffo:
Try disconnecting your coin door and marquee lights.

Is there a ground wire attached to the frame of the speaker.

Darren01274:
Hi there is no problems when using PC speakers through the Line Out sounds fine. When I use Arcade Speaker with Jamma wires I get a bad hum/buzz with game sounds. I tried connecting ground wire to metal of speaker no joy really. Am I wiring it up right? 2 wires to two of the solder points on speaker.

BobA:
That is the only way to wire a single speaker.
