ground loop reducer/isolator.

But that dont always work, (not very well atleast)

Find a new ground. If nothing else, run a line off your batt. That'll delete all that unwanted noise.

ground loop

Yup, it is a ground loop problem. They can be rather tricky to resolve but search these forums for "ground loop" and you'll find a couple of threads with suggested approaches to resolving the problem.
