Amp going into protect mode, checked all my wiring
Morning guys, I had a weird problem last nite. My speakers made a loud whine(not alternator whine, ground loop issues) and then the amp went into protect. I tested my RCA's and they worked fine and the amp still plays music when I connect my ipod straight to the amp. But the problem is that as soon as I connect the Amp to the motherboard, there is loud whine/pop noise and the amp goes into protect. I also have a USB DAC and it does the exact same thing. So i thought that maybe there was a problem with the Audio out on the motherboard or off my USB DAC but when I connect my headphones straight to the motherboard i still get music with no noise. I know it's not alternator whine or a ground loop issue(i think) because the speakers make a loud whine then the amp goes into protect mode, until I unplug the RCA's from the mother board. Any help is appreciated. I spent a couple hours testing and can't figure out what's happening.
