Help with connecting the Bluetoth module to the speakers

Hello to all the inhabitants of our sites!
I will give the keyboard to my son, he wants to ask everyone a question.
So, I have a Bluetoth column.
There was a problem of applying the circuit from the bluetoth column.


I tried to find the contacts of the output of the transmitted sound to the speaker without amplification, in order to connect computer speakers to them.
I managed to find conclusions, but they turned out to have such a weak signal that the speakers did not perceive it, but there was sound in the headphones, but very quiet.
I could not find the pinout of the Bluetoth chip.
Although her model visible and it is called: BDGN430 184OUDZ
Here is her photo.

Thank you all in advance, this is the first attempt to write an article with my son.

Maybe the speakers are dead? If you touch their entrance with your finger, is there a background?

Then the connection error: the speaker input is more sensitive than the headphones, and the input impedance is higher.

Exactly before resistor? That is, on the side of the bluetooth module?
there was sound in the headphones, but very quiet.
Headphones connected directly to your board? So they should "strangle" the signal: their resistance is a maximum of 32 ohms.
the signal is so weak that the speakers didn’t perceive it,
That is, there was no sound at all, although it is in the headphones?

Guys, I confirm co-authorship - please comment on it.

I did so, and there is still a weak output signal, and if you take the output from the amplifier, then there is a lot of distortion.

We must not look at the output of the BDGN430, but look at the input of the amplifier 8002. Moreover, not on the leg of the microcircuit, but to the resistor connected to pin 4 of the IC, unless, of course, it is turned on according to the standard circuit.
