A few days ago we received the chips we hadn't to start the stereo. So we ran the tests on a breadboard and it worked pretty well! A few noise we reduced using 47pF capacitors at the audio input.

So I updated the scheme and added the second speaker. As we have not receive yet the bluetooth module, we are simply using a jack to test the whole thing. We got a 60mA current for a 12V voltage.
