He doesn't mention turning the ignition back to on, just turning it off. We are all just used to the empeg's stand-by feature and being able to wake it with the ignition off. We forget other HU's don't do this. I am assuming that since he is running an Alpine HU, he is feeding the empeg into the AUX input of the Alpine, then out to his amps & speakers. I'm betting his remote turn on is connected to his Alpine HU. With the HU not getting the signal to turn on from the ignition sense wire, it is not turning the amps on. Hopefully I clarified what I was trying to say.
