Capcom big blue : speakers not link to the jamma cable

Big blue that was converted into a system 246 (Ps2 basicly) to run tekken. I've at least changed it to run capcom fighting jam but to make it run a cps2 system would be even better.
Simple enough, or at least it should've been. Video does display but no sound going through as i suspect the jamma connector isn't wired to the two speakers.
See the photo for the adapter in between the system 246 and the jamma connector. i suspect the connector to the left of the jamma to be the kick harness. The two RCA must be the audio input from system 246.
Any ideas how to link the audio from a CPS2 given the available cables?
Redoing all the wiring from scratch isn't an option considering my knowledge level.

The white/red RCA cables are the audio out from the System 246, seems to me you would just get a longer set of cables, and ignore the Jamma adapter board and run those instead directly into your q-sound amp.
 
Hm, if the cables were longer it would change nothing, as the goal is to connect a cps2 instead of said system246. Sure the CPS2 has similar output that could be used, but again, the jamma need to be connected directly to the the CPS2, while the RCA connector is on that adapter board.
As for the Q sound board, i beleive whoever did this convertion back in the days had it removed! So i get from this that if i ever want a CPS2 in that cabinet, a Q sound board need to be acquired?

Maybe a better question to ask first is, how are you getting sound today using the System 246? Or are you trying to say you're not?

You probably should post a picture of your cabinet. Not all big blues were/had Q-sound amps.

There's a Big Blue guide here if you search that will show you all the differences between the cabs.

I do have sound from the system 246. And it goes from the system' race output, to the JVS adapter.
Here's a photo.
Wiring RCA from CPS2 to the adapter, and have the jamma directly on the cps2 didn't give a workaround for the sound . Somehow a way around the adapter completely need to be found.
