Hi All,   did anyone successfully remove the central speaker mesh cover from the Canton system in Octy 3? What tools to use / how to un-clip it / does it break easily / how to protect the soft dashboard form damage / ... ? I'm having some ugly resonance every now and then (mainly in mid range / speech range) and I would like to open it, check for damage / loose parts. For clarity - please see pics below: one shows the cover as a spare with clips visible, other is the actual one in my car.
