[Solved] Connecting Nokia Subwoofer 8L0035381D with Audi: Wire Configuration Query

Hello
I wanted to install an original audi subwoofer with the NOKIA number 8L0035381D. I found this description of the cables in the cube on the electrode:
1 - + 12V permanent
2nd and 3rd output to the left loudspeaker, diam. and height tons
4 - mass
5 - on / off control + 12V
6 - left channel input
7 - right channel input
8 - input mass
9 and 10 right loudspeaker output, diam. and height tons

I was struck by the fact that in my cube (red, original) in position 1 there is a black wire, in pos. 4 red, which would indicate that in position 1 there should be a minus and in position 4 a plus (according to the color rule). Does anyone have any experience with connecting such a sub?
In my cube, the wires are arranged as follows (I entered the numbers as they are on the cube from the back)

Could this mean that someone surprised me and placed the wires in the ankle? Or is it supposed to be a minus and a black plus? Which cables should I connect the RCA signal from the radio to? Is the above mentioned from this cube? If it is not from this, does anyone know how to connect such a sub? Which wires are from what?

Hello.

I managed to unravel this amplifier.

It is a four-channel amplifier based on two TDA8563Qs, where the left IC powers the door loudspeakers and the right IC powers the two-coil speaker in the subwoofer.

In the attachment there is a diagram with descriptions of both cubes and basic transitions on the board.

Thank you for the wiring diagram, I hope it will work ... I will try to adapt this amplifier to a separate subwoofer ... Regards.

Gentlemen, I will take your advice to heart and I will also fight this system
