Jaguar XF crackling sound from speakers.

[ARNSK68]

I have a crackling sound coming from the speakers, when driving home yesterday the stereo kept glitching so turned it off, noise still there, arrived home and switched off and you could still hear the crackling sound coming from the speakers, doesn't seem to happen when the car is cold so could be heat related, I have tried googling the problem but can't seem to find a definitive answer. If anyone has come across this annoying problem before, please could you let me know, your help and advice is greatly appreciated. It's the Meridian system if this helps.

Kind regards. Arnie.

Could it possibly be something stuck in a vent of the cabin sensor? That's the little grille in the lower bolster of the dash, usually driver's side.

Thank for your input Jim, not sure about the grill but will check anyway, I have listened to all speakers today and have found that the crackling is only on the front door small top speaker and the tweeter on both doors, all other speakers ok, this is happening after about 5 mins just sat in the car without the engine running.

Thanks again.

Arnie.
