Hey,
I'm planning to retrofit a Nobsound G3 (TPA3116) into factory car stereo. The plan is to wire up the car stereo volume knob to the TPA3116.
My issue is that the TPA3116 uses a 6 pin 10k potentiometer, whereas the car stereo uses a 3 pin 10k potentiometer. How do I wire this?

Oh so that's what it is. Great solution! Is there an impact on sound quality?
I'm very new to electronics so this is basically in a different language 😱
If you want stereo output (not sure what your input is) then you may be better off to mechanically adapt a stereo potentiometer to your old radio chassis.
I was thinking that but it's impossible to find since it will need to be a push-push (for on-off switch) double gang pot with a long knurled shaft. Going with a shorter pot would sacrifice the original knob and trim, which would make things look weird.
I looked into extending the existing TPA3116 volume pot but can't find any knurled options.

For mechanical reasons use the original pot, none other will fit there.
If original sound source is mono, no stereo pot will make it stereo, so don´t waste time on that.
Solder a mono audio cable (center conductor and screen) to current pot ground and wiper, connect other end to one 3116 or whatever , connect that input in parallel with the other 3116 channel input.
Each will drive its own speakers, you will have dual mono.
Better than nothing.
By the way, what PRR said on answer #2 .
By the way 2: you keep mentioning:

It´s not, but a plain MONO car RADIO.
As Fahey said:
Connect the mono pot in the radio to the 3116.
There is an AUX input, I assume it's a 3.5mm stereo jack.
Make a cable from the pot in your radio to the jack that go's in to the AUX.
Place the amp anywhere in the car and of you go.
No need to find a pot that's probably unobtainable.
