Why Does My Car Amplifier Go Into Protect Mode When I Turn Up The Volume

I know this question seems to be asked 100 times, and I’ve read all the posted answers to other people asking the question. However, it seems that no one else has had the same experience that I do.

First the basics:
Sub: Kenwood KFC-W2511 10″ rated at 300W RMS 4 ohm (1000W Peak)
Amp: Sony Xplod XM-1252GTR rated at 340W x 1 (Bridged) at 4 ohm
125W x 2 (Not bridged) at 4 ohm
800W Peak
Headunit: Stock with Line Converter (Converts speaker wire from head unit from regular speaker wire to RCA)
Wires: Tsunami 8 Gauge Wiring Kit rated for 800W
Car: 2006 350Z

The problem I have is that when i begin to turn the volume up, the amp Protection light goes on. I have tried Bridging the Sub, I have tried not bridging the sub. I have tried changing the amps location, changing the grounds location. I have taken everything off and reattatched wires one at a time. I shortened the power wire from the battery, and the remote wire from the headunit. I’ve turned down everything, and began slowly increasing the volume and the protect light goes on at about 10, max volume is 30 on my car’s headunit. I have also tried every combination of these actions possible. Volts and Amps appear to be good and well according to the Voltmeter. I have never had this problem before and I’ve installed at least 15 systems for myself and friends. I’m at a complete loss, and am considering pushing my car and all stereo equipment off a cliff.

Any ideas?
