MAN TGA Original Subwoofer Connection: Step-by-Step Guide for 6-Wire Amplifier & PCB Setup

I bought an original subwoofer from MAN and would like to mount it, but I have no idea how. The subwoofer is probably together with the amplifier, so it goes with 6 wires.
The wires go to the PCB (6 pcs) and the PCB has two to the loudspeaker.
I have no idea how to connect it, someone will suggest something?

Little information, please provide model, type etc.

This is what this speaker is about


I tried like this:
plus to blue (remote)
plus on red (power)
black - mass

And I still don't know, because it stays brown, white and gray and I signal them from the radio and nothing.
Good game, you still had to put 24 V on gray. Until closing.

Were you connected? Do you know the description of the findings?

I am going to connect a subwoofer, the car originally had no place to get plus 24 V.
