Could you point me where exactly should I solder 1500-2000 uF cap ?
25V or 35V of the cap?

Strange...when I posted this reply, it works after click on thumbnails.

Best possible fix is like attached. Remove red marked components, solder wires in place like shown.
Drawback:
No volume control via potentiometer anymore
No Aux/Line-in (Aux might still work if they used the ADC of the BT-module.)
Keep the wires close together (R+/R- and L+/L-)

Hello, many thanks for possible solution ! I will test it this weekend.
One question:
From point where (R+/R- and L+/L-) is marked I go directly to speakers +/- terminals (skipping connecting speakers cables to blue terminals on this board)
From what I understand I'm leaving after this solution option with adding capacitors.

In both cases it was a static noise. Without mod the noise is way to high ! When music stops, only the noise comes from the speakers. For exemple when I turned on this device, and device is waiting for BT connection - only noise is present.
After the mod noise is still present - static, but value of this noise is much less - let's say on acceptable level for me. Of course in perfect scenario the noise could be gone
