SOURCE: Avr Shuts down at high volume
It does that because there is a safety feature in all the newer devices. If your system is turned up to high you would blow your audio outputs or speakers. That's why it shuts off.

SOURCE: power problem?
1. Is the head unit powering the speakers directly or through an amp?
2. What ohm load (4,8,) per channel and how many speakers?
3. Does it do it with the bass set all the way down?
If you have access to a voltmeter see what the voltage is on the yellow and black wires when it is diming. It should be stable ~ 13.5v with car on. if its < 10v when dimming either there is:
1. Shorted speaker lead.
2. Bad ground to radio.
3. loose power feed to radio.
4. Ohm load below 4 ohms, causing the eccess current draw.
