constant buzzing noise from speakers when opening the door

[Question Mark]

Vehicle: Volvo xc 70.

Components:
Gladen Utopia
Mosconi dsp 6to8
Mosconi Zero 4
Mosconi As 100.2

I get a constant buzzing noise when I open the left drivers door. Signal cables are on the carpet  (I think this Source for the distorion is excluded) . Appreciate all the help I can get.

Do you have a adaptation module to connect the head unit to your stock audio plug in the dash?  Maybe that thing is adding noise to your door chime signal

It does not matter when I use the original head unit or signals straight from the phone.

Actually it could matter.  The signal from the door dinger might be introducing noise to your sound system regardless of your audio input.  So my question still stands.

I think you are right. I will buy an adapter cable set tomorrow to check with another head unit

Just check your connections to that module.  Its probably a loose wire or something.  I literally cut my module out yesterday, which is why I replied to this thread.  I was dealing with similar headaches.
