When going through the harness (was a conversion from another game), I noticed the two (2) 4 Ohm / 5W speakers are connected in parallel (I think), but one of the non-ground speaker wires was disconnected. I'm guessing it was supposed to be on pin 6 on the connecter (solder side). Before I resolder it back on the connector (pin 6 as well), wanted to make sure that the speakers should be in parallel and not serial. Wasn't sure what the gallag board could drive.

I'm no speaker expert but every Galaga/Gallag I've done is set up for one speaker only. So I would stick to parallel as to not overdrive the audio chips on the PCB. Maybe check here for speaker load amps.

Just my .02
