          In manualul de utilizare scrie asta  "THE PURCHASED DEVICE IS ONLY SUITABLE FOR AN OPERATION WITH A 12V ON-BOARD ELECTRICAL SYSTEM OF A VEHICLE". Deci la 13 v sau mai mult e posibil sa intre protectia la supratensiune, totusi diferenta de 0.8V mi se pare cam mica.. daca asta e problema, incercati cu un regulator de 12V pe alimentare.

          Mai verificati o data conexiunile, tot in manual se mentioneaza si simptomele cu posibile cauze si remedieri, in cazul protectiei:

"Malfunction: amplifier runs into protection mode (red protection LED lights up)

1. Short circuit on the loudspeakers or cables.>>>> Check and reconnect the cables.

2. Overheated by too low speaker impedance.>>>> Choose a higher impedance speaker or a new speaker setup

3. Insufficient air circulation by a inappropriate mounting position of the amplifier.>>>> Change the mounting position Ensure air circulation

4. Overloaded by insufficient power supply (too thin profile section on the power cables).>>>>Use a bigger profile section"

De unde stabilizator de 12V la curentul ăla? Probabil are ceva defect in sursa amplifului.
