Audi A4 B5 Avant Rear Speaker & Subwoofer Connection: Non-Original Radio Module & ISO C1 Cube

Hello,
I have a problem with the rear speaker and subwoofer on the Audi A4 B5 Avant.
The game only plays front so I decided to do something about it (I mark it) I bought a non-original radio module and some random module with an iso c1 cube (yellow), which I cut from it because I needed it and the car was broken.
And here is my problem, the cables that protrude from the car are of a different color than those at the ankle. I warn you that I found the scheme on the internet, but it did not help me, just like looking for schemes by cable colors (where I will not find such a scheme are different colors than mine).
Let someone write which cables to connect with each other so that it works as it should, for ease of use I numbered the cables in the pictures.

ISO C1 cube:


Leftovers from last (or whatever was there):

Measure with an ohmmeter the transition between each speaker wire in turn and the cables coming out of the radio pocket and you will know which wire is from what.
What is this radio, where to connect the rear speakers (to which pins) you need to see on the diagram of the radio.

I do not have an ohmmeter, and I do not know if I would figure out which cable is what it is after its resistance, (I am green in what I mentioned), there is no other way to find out what and how?

By the way, when it comes to these pins, the whole scandal is about finding the equivalents of these 4 cables, yes? (I mean these 4 at III):

Do you have a subwoofer in the rear wheel arch at all?

Yes, it is true without an amplifier, but a friend said that it can be connected to the power supply of the radio and it will be weaker, in general I mean to check if this rear and sub works at all, I bought the car without the working back, and now it combines and fights with it.

And where the amplifier comes from the original subwoofer. So what are you writing?

The cheapest multimeter with a resistance measurement function is PLN 10 (simply by applying the meter to both ends of the cable the resistance will be 0). There is no simpler method.
You can also check the bulb by applying voltage (+) to each individual cable individually, and by touching the bulb on the other end of the cable and to the ground (-) determine which cables. (but if you are completely ignorant of electricity and do not understand what to do, you better not do it because you can break the radio or burn fuses.

I repeat the question, what is the radio model? Because the connection diagram depends on it.

I sign out because I'm asking, I mentioned earlier that I don't know anything about it. There is a bay next to the subwoofer, I thought it was a boost, but as you can see it from the changer probably.

Some Chinese: Dibeisi model DBS006

So there is an amplifier in the subwoofer.
