992.2 sound system 'womp'

[Beanie]

Weirdly at sporadic intervals I have what I can only describe as a 'womp' that comes through the speakers, doesn't matter if its radio, music from phone or phone call

Anyone had anythihg similar?

Its starting to p155 me off so itll have to go in for diagnosis, but useful to know if a common issue

Is it the speed limit warning?

No, definitely not, more like distortion through the speakers
