Help please. When I change a function or press certain (most) buttons on my head unit a nasty crack is heard in the speakers. I have even stuck an alternative head unit in, as get the same result.

Any ideas of reolving this one please.

Take the ground from the HU and wire directly to an alternative grounding location.

Thanks. Earthed and re-earthed, but I still get a pop in the speakers. Any other ideas please?
