That "hiss" voltage level is what triggers the signal sensing circuits. This issue is not present in any other BMW OEM amp -Logic7 or HiFi amp in the E60- where the remote turn on signal is triggered right after opening a door (OEM amp turn on by opening a door or trunk by design) and no music playing at all.
does it have to be triggered by the sub outputs?
or is the voltage on the fronts/center/rears too weak?
