Question about Audio Players & Recorders
I know you say all your cabling is correct and I don't doubt you at all. However, the problem you describe sounds an awful lot like a short or an impedance problem with your speaker wiring. Make sure that the ohm ratings for your speakers are correct for your amp, make sure that the + and - wires for each speaker don't touch each other (especially easy to do where they connect to the amp), make sure that no speaker wires are cut or crimped (easy to do if you are burying under a baseboard or something), and finally make sure that all the speakers are wired correctly and are in phase.
A good test procedure is to remove all speaker connections from the amp. Then run new (test) wires from the amp to just your front speakers or to two known-good speakers with correct ohm impedance. If the receiver works that way, it tells you that you have a problem somewhere in your wiring.
Good luck and please let me know if this helps.

Should the amplifier go into protect mode, simply disconnect all RCA and speaker leads, while keeping +12 volt, power ground and remote leads connected.
1. Now turn the amplifier back on, and if the diagnostic LED lights, the amplifier has an internal fault.
2. If not, plug the RCA cables back, and reset the amplifier. If it goes into diagnostic now, the fault lies in the input, either with bad cables or source unit.
3. If the amplifier seems fine with RCA cables plugged in, connect the speakers, one at a time, and if one of the speakers or its wiring is faulty, it will activate the diagnostic
