IMAY I tried the 04 reset aud setup today and also looked at the DTC.  I had no sound on 2.4.5 channels.  I am attaching only the 1st and 3rd photos.  I already suspect that the amplifier does not want to be in my car
on channels 1 and 3 the sound was normal. I connected the speaker as you wrote. maybe the problem is in the amplifier.
