I only partially understand the type of modification made. What I would like to know is exactly what the effect of this modification is on the PAM amplifier circuit, since this information is not absolutely clear in your video. I understand the volume control by potentiometer. I deduce that the potentiometer that has associated capacitors is a passive tone control. In fact, I can't clearly understand the effect of that potentiometer, because you placed the LEDS on the speaker cone and that just makes mechanical noise. And the video ends abruptly, precisely when it was important for everyone to notice the effect of the potentiometer in question. I'm looking for concrete information to deal with PAM modules, mainly in the context of audio performance. Would you mind clarifying this? Thank you in advance.

How did you "Enhanced" the pam8403? ???
