I am installing a carputer and removing the HU and installing a switch panel in its place. The switch panel is power by the power line from the HU. When i first flip the switch the amp turns on and the speakers are at a medium power level. After a few seconds the volume decreases so I can barely hear it. If I flip the switch back off and on it does the same thing. The amp is not showing any warning signs. car is off so its just under 12 volts. Any ideas why it would be going quiet after a few seconds?
No announcement yet.
