TPA3116 2.1 Channel BT - Sound cutting every 1s @ low input (video)

fauxfrench put me on a good track.

Those amps are shipped in a bubble wrap, poorly protected.

One capacitor might be in fact damaged.



you wont see anything with those small cheap speaker. Its noticable on the 12''

  • right click and stop music
  • left only stop music
  • sub still running fine

the ''sub'' 6.5'' is on the back .

See the inside, with a new smaller chip. Sound is better with this chip, but 50wx2 isnt very louHell
Thank you very much overdose for uploading those photos. Please do you mind sharing the block diagram or even circuit diagram for this project?
