Shielded power wire is not necessary.

The current noise could be caused by a lack of ground to your pc case.
Quick fix run wire to the case from a ground point of the chassis; metal screw into body or frame.
My inverter setup did the same thing until I grounded the case.

Any reason why it the exact same setup didn't do it in another car?

I was also wondering what kind of gauge wiring I should use since I'm still using the stock power supply cable. And would this all go away if I just installed my carnetix startup controller?

Was the pc case mounted differently... like touching metal anywhere?
Have you tried grounding the case to the chassis???

No, hes has some walmart head unit.
The case isn't touching metal anywhere else. I was thinking about it, but wasn't sure because the pc worked in my friends car.

What stock psu cable do you mean? The molded IEC that came with your PC? That's not telling me much.

I am still using the stock power supply that it came with. I'm not sure what gauge it is. I was asking because everyone says I should ground my pc chassis, but I'm not sure what size gauge wire to use because I don't know the stock gauge. I read somewhere that it should be the same ground cable gauge as the power supply cable.

Yes this will all go away
life, the universe, and everything... ( deep thought )

Seriously? the ground noise distortion will go away when I install the carnetix? I wasn't sure if you were kidding or not sorry.

Different cars have different electrical systems, different wires, going to different places, and of course, different grounds running to different points, with different amounts of resistance. That is why every car, EVEN AN EXACT SAME MAKE AND MODEL, can have different results when it comes to noise.

Ground should always be the same gauge as the power wire. If you are just grounding the case of the PS, then almost anything will work, just keep it as short as possible.

Your Carnetix COULD, but there is no guarantee that it WILL, cure the noise problem, but ground loops can be introduced with any and all equipment, DC-DC or inverters.

I was kidding.
Your questions are really vague.

I read somewhere that I shouldn't ground it to the battery. I was wondering why?

When I say stock unit, im referring to the 2nd picture in this post.
How do I connect my carnetix to my aopen mini pc?

I'm sorry I'm vague. I'm not sure how to describe what I'm doing. So ask for details and I'll try my best to answer them.

Thanks Wired btw. Can I splice the ground from the case to another ground wire running inside my car?
