Ok, taking you up on this offer.Don't forget to add a voltage divider to attenuate the audio or you'll likely blow the speaker.
- I am using this speaker: PB-3212PK

Actual ground. Replace in/out in the circuit for positive/negative and it will all make sense.@ic3b4ll, cool. Question concerning ground for these circuits. Can we consider JAMMA pin L (Speaker-) as ground? Or does this circuit need to be tied to actual ground?
That's a good suggestion! Next time just edit the response, we can't use that in this PCB but it may be useful in the futureI suggested a circuit to convert unbalanced to balanced audio using an isolation transformer (TY-250P is great), but it doesn't fit in this circuit and you are using a speaker.
I started another thread for the test bench PCB. Keep this one on topic of fixing the S16b audio.if you want to convert from a potentially BTL speaker signal, to a line-level then you can get cheap adapters intended for fitting between car stereo's and booster-amps
