Hello together, I recently installed an eton move m12 400a, so far so good. However, if I turn up the loudness there is more exposed and if I turn on louder the sub goes off. The power lamp still lights up and the protection lamp does not work either. I have tried it with a high low adapter, also can not. I connected the sub to the rear boxes, because it did not work at the front, because the sub only played very quietly. Abe r when I put my fader completely on the rear boxes and thus the front no more sound of itself I can fully turn up and everything works so I don’t think it can be a current problem because the voltage at the woofer I measured and there everything fits. Maybe one of you has an idea what it might be. Lg Flo
