Question about Sony XM-475GSX Car Audio Amplifier
The amplifier may be bad with a malfunctioning circuit inside. Also, it could be getting low voltage...make sure that the amp is getting 12 volts or more at the constant and remote leads. If it is connected to speakers, make sure that they are measuring more than 2 ohms (using a voltmeter). A good stereo shop can check this for you too.

Should the amplifier go into protect mode, simply disconnect all RCA and speaker leads, while keeping +12 volt, power ground and remote leads connected.
1. Now turn the amplifier back on, and if the diagnostic LED lights, the amplifier has an internal fault.
2. If not, plug the RCA cables back, and reset the amplifier. If it goes into diagnostic now, the fault lies in the input, either with bad cables or source unit.
3. If the amplifier seems fine with RCA cables plugged in, connect the speakers, one at a time, and if one of the speakers or its wiring is faulty, it will activate the diagnostic
