Speaker buzzing constant

[Q7tdi]

Hi was wondering if anyone has any ideas about a buzzing noise coming from the speakers on the q7 started with the small rear door now seems to be at the front in the centre of the dash! Doesn't go off when you switch the car off either? Anyone come across this before?

Sorted!! Found that the driver sill trims have been removed at some point and when it's been refitted 3 speaker wires had been trapped in the clips and shorting on the car body.
