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 missed that part. I thought it was just Empeg->amps.

Yeah, if he's got it wired Empeg->Alpine->amps, then of course it's not going to make any noise when he wakes up the empeg with the ignition off. He can get rid of this by setting his standby timeout to 1 second so that he's not likely to wake up the empeg ever.
