Cayenne 958 front speaker issue

[Output Flange]

Hi chaps,

Car is a 2012 Cayenne with the standard audio system.

As of a couple of days ago, both from dash speakers have stopped working. The door panel speakers are fine.

I’m assuming I’ve disturbed a connection somewhere, but don’t know if there’s an amp somewhere in the car? I know if I had Bose it’d be in the boot side panel.

Any thoughts?

It’s definitely either something loose or failing
