It's only started happening recently . Ive not changed anything apart from the headunit settings, but ive always done that anyway. Cant quite work out why its suddenly started doing it .

it IS a bad earthing problem.. sometime this is due to the amp itselft not the cable... so take your amp to the peeps you bought it from

It can be caused by static build up too, cant remember how to get rid of it though.

Ground loop isolator or a filter on the RCA's should sort it.

a cable from the amp housing straight to ground will sort it

The casing of the amplifier is usually already grounded inside if you take it apart, so cant see how that would make a difference?
