    Power line filtering

    How important is it to filter the power into a headunit?

    If so, should I use a series inductance, a shunt capacitance, both or something else? and what values?

    Yes, the supply line. I'm thinking of noise and voltage drops.

    If you have a noisey power line(alternator), why not use this:

    That is if everything is grounded properly in the cabin and engine compartment.
