    Whay re-invent the wheel.

    If you have a ground loop, you should fix it by grounding everything to the same point.
    If for some reason that does not work buy a ground loop.... many are available.... try a search for installs that use them.

    just filters to block frequencies over a certain value....you definitely don't want to use em if you want to retain sound quality. they tend to cut off the highs and lows to get rid of the ground hum

    I think that's acceptable...more than earing the sound of the engine

    the best thing is to get 1 and install to alternator thats the most likely cause of your noise

    alot of old cars used to have them fitted to the outside of the case

    allso cheap car radios have them its the big black block with the power supllys going though them

    alternator

    ..thing is..how do I do that . By the way since I installed my carPC the sound of my headunit(radio) with FM doesn't work pretty well . If my car is stopped it's just make noises.and if I shutdown the computer the sound comes. The ignition 12V wire is the same could that be it?

    yeah, i thought that was acceptable too...until I tried it out. it was actually unlistenable to me.

    btw...it really sounds like to have a grounding problem. try to find a bare metal spot to ground both your pc (including various metal pieces like the backing plate) and you HU to...and don't forget the power supply ground.
