Original subwoofer with Chinese stereo

Hello,
I installed a Chinese head unit in my Audi A1 sportback (stock model)
My issue is that I added an original Audi A1 subwoofer (it's ergonomic without altering the car)
But how do I connect these two devices?
On the Chinese head unit, there is a green socket labeled subwoofer but what should I do with it?
And the standard red and white RCA outputs.
Just to clarify, the subwoofer has its own Audi amplifier that I need to connect by identifying its wiring ???? this is not going to be simple!...
I often take on improbable projects ????
Thank you for your help ????

Hello,
In addition to being on the wrong forum, I strongly advise you to see a mechanic and not to skimp on the installation since you do not have sufficient knowledge.
The prices charged will be nothing compared to the total loss of the vehicle without coverage by insurance.
A wiring error can easily lead to a fire: the currents involved in a subwoofer can quickly be high (10A for a simple 120W)!
The MAANG don't have oil but they have data!

Thank you for your perspective on the problem; it might be a mistake to think I would back down in front of one or more issues.
In 50 years of "DIY," I have never been so incompetent as to not protect a setup with the appropriate fuses, so thankfully I have never had a fire.
However, equipment and materials evolve, and one must constantly adapt.
As for mechanics, that's another topic; this is pure audio we're dealing with, and while browsing various forums in search of "reliable" information, even the pros seem to struggle.
My problem is complex, but I have successfully connected subwoofers and had dozens of functional setups.
Hello,
What are the references (Brand and model) of this Chinese unit (or a link to the purchase site)?
The Subwoofer output is normally the socket to be connected to the subwoofer.
You mentioned RCA (Red-White) sockets; who do they belong to, the Chinese unit, the car, or the subwoofer?
It's very difficult to catch a black cat in a dark room.
Especially when it's not there...
At first, I had dreamed that the enclosure could work in passive mode by directly plugging in the green plug marked Subwoofer, but no sound comes out; it must just be a plug with another signal.
So, I need to switch to active mode and power it in active mode via the Audi amplifier, but first, I need to figure out what does what for inputs, outputs, power, etc... there is no RCA plug on the amplifier, just a female pin.
I am also attaching an image of the harness from the unit, except that I don't have a canbus; the car doesn't have steering wheel controls.
Once again, thank you for your help????
Curious isn't it, two times RCA-F-R and RCA-F-L (Front R and L) (RCA 4 and 5 and RCA 6 and 7)
In my opinion, one of the pairs RCA-F-R and RCA-F-L should be RCA-R-R and RCA-R-L (REAR R and L)
I'm not an expert in car radios, but that said, the Subwoofer output may very well need to be connected to an active system (in home speakers, most subwoofers are active subwoofers).
Can you provide the link to this car radio, presumably on Amazon?
