Hi,
Amps normally have several kinds of "protection" modes. Common ones are thermal, voltage, and short. Do you know which one you have? If the amp isn't hot, and goes into protection immediately before doing anything, we can rule out thermal protection. The next thing you should do is disconnect the speaker/subwoofer leads from the amp so that it only has power, ground, and remote connected. If the amp comes on with no speaker load, connect the speaker and see if it goes into protection. If it does, then you probably have a short-protection. Hope this helps.

The amp will require service. One or more power transistors have failed and the protect circuit keeps the power supply from blowing your speakers

clipping as indicated by its light? if so then you have overdriven your output. i dont know about Crown their protection but normally such indication you have problem with either your load speakers maybe shorted but still audible or maybe your input stage overdriven also.

If the amplifier goes into protect when there are no speaker wires connected to the amp, the amp is likely defective. The most likely culprit is shorted output transistors. If it's new, return it to the place of purchase for repair/replacement.
