Ford Fusion - Ford speaker crackling with ignition off - kayaker steve

I have a weird problem with my 09 plate 1.4 Ford Fusion. With the ignition.engine off and car locked, I get an intermittent, loud crackle through the stereo's speakers. The stereo is the factory fitted unit. Stereo works fine when driving. Is this a common/known problem?

I wouldn't think so, probably a fault with the stereo.
