The issue is that noise from the alternator is getting into the head unit via the power cables.
They won’t necessarily be whining noises, but they can be.
In some cases, you may also need to isolate the amp or install a noise filter.
Patch cables, ground wires, and other components can also pick up unwanted noise.
Ground issues are often solved by cleaning the ground location to ensure a solid connection.
