As soon as I attach the low level inputs, I get a protection light. This is with the remote line powered, and without attaching the 12 volt power source. The speakers work on my home audio system. Not sure what else to do. The amp is multi-channel, I am only using 2 channels. I followed the diagram in the owner's manual..... help?
