Potentiometer Amp2

Hi all,

I am trying to mount a speaker with an Amp2 and a raspberry pi 4. I am stuck with volume control:

  • I have tried using a rotary encoder but every time I try to increase or reduce volume, music stops for a little bit (less than a second)
  • I also have tried using a stereo potentiometer (logarithmic, for sound systems). I know that using this solution will imply to go have an independent control volume ( if I decrease volume manually, I have to increase manually again if I want to gain access to full potency) but I have no clue about what variable resistance should I look for. I think that amp output is 30W and 2A, right? How many ohms should I use for the variable resistance?

Thanks in advance.
