I get the power-off pop just about every time I turn the car off (Empeg running). In my install, the Empeg is going line-level into my factory head unit, an Eclipse made by Fujitsu-Ten. I don't know if they offer tech data on their website or not. I haven't put in the resistor that the Empeg team recommended because it doesn't bother me that much, and no one else seems to notice. If the MkII still has this issue, I'll put in a resistor when I change out the sled.
