Riiiiiight, I remember now.

Yeah, someone else did this, too. They had their amplifier remote line (blue wire) miswired somehow, so that it was connected to a power source instead of being the power source itself. It had a similar symptom.

The amp remote wire should be connected to exactly one thing and one thing only: The amp remote activations wire on your amplifier. Anything else and you could risk shorting stuff out.
