Decibel settings are to high, and balance in left mid l, left mid and right also in right speaker does "Radio check it self if to much power is going to the radio", nothing wrong if cables are correctly connected. But to high amplified sound settings can make the radio to go off because to much power is taking out of the battery. If you set all 5 channels 100 decibels and 110 dB and 10 for the speakers,
radio settings can make the radio go off in till you disconnect the music source and set the settings correctly.
