    Just a suggestion. No warranties offered, expressed or implied. I cannot be held responsible for anything that goes wrong. So grounding the ground after the egg is a bad idea, sorry. Everything I suggest is my opinion, and who knows if it's even a good one. I'm sorry, I don't suffer from the same problems as you guys. Used to, but I've since then grounded every possible point I could, and it sounds crystal clear. Good luck man.

    Something else I was thinking, do the lilliput screens have like a metal shroud around the screen? Maybe ground that too.

    Its okay , i dont mind the suggestions. how did u ground ur system that u got rid of the noise ? how many different grounding wires do you have set up on ur system? i would run a thousand different wires to a lilliput if i though that was going to help but how many should do it ?where did u ground it too? thanks

    I grounded all my points to the same place on the chassy. My mobo has 2 ground points, my screen has 2 or 3, my PS is grounded, my ground on my ac out of the inverter is grounded, my ground on the sound output is grounded (this one helped the most), and my USB shield wire is grounded.

    Edit: forgot to add, I grounded both my screen pcb and my actual screen, it has a metal shroud on it.

    are you talking about wiring the wire itself or how is it?

    I couldn't even read through the whole thread without skimming....so if you've already tried this then well damn.
    That Lilliput egg SUCKS. It was the only thing causing noise in my system. Have you tried the system without the lilli plugged in? It it does help you should get a fairly low wattage 12-volt regulator or (easier!) get a cheap inverter and use the AC brick that came with the screen. I run my laptop, screen, and usb hub all off my cheap inverter and I don't get any noise now.

    I had the same issue in my Acura - and I could never fix it with an inverter in the system. I didn't see anyone else mention this, but have you considered a DC-DC laptop power supply (the ones they make for laptop use in cars/planes?) These are very well regulated and filtered, providing much cleaner output than reasonably priced inverters. I ended up going this route, and I came to the conclusion that the inverter itself, grounded well and everything, was a significant source of electrical noise throughout the vehicle (even with no carputer, the factory bose stereo, stock configuration, would whine while the inverter was on). I have not had these issues in other cars with inverters, but hey, that's one I can't explain (even as an EE). My Acura carputer works very, very well now with no noise... I know it's another $60 or so, but you can always take the thing back if it doesn't work... Just a thought. Hope it helps!!

    Yeah, basically I just spliced into the wires and grounded them.

    Here Is Some Clarity!!!

    I just skimmed all these pages but I will bet my left nut that the alternator whine that many of us speak of is not alternator whine at all, but HD noise or just MB noise getting into your line out/usb out line. The reason you havn't solved the problem is that the problem probably is coming from INSIDE your computer not your car or ground points.

    The reason I say this is I have the same POS problem. I have a high pitched whirring that you can hear anytime the PC is on. It doesn't go up with the accelerator nor the music volume and I mainly hear it when I am not playing music. "weweeeeeeeeeweeeeeeeweeeeeeeeeeeee" That's what it sounds like.

    1. I first wrapped my entire HD in tin foil............No help.
    2. I next wrapped all the internal audio wires and line out/headphone connectors in foil.....................no help.
    3. I then grounded the pc frame to the car....................no change.
    4. I then plugged Headphones into the audio jack and I could faintly detect the same whirring. It just wasn't as annoying because it wasn't being ampliflied anymore.
    5. Lastly, and this is the big one. I took the pc into the house (AC) and I still get the same whirring sound, very faintly in the headphones when pc volume is at a minimum. It had nothing to do with the alternator or RCA cables or anything and everything to do with my crappy onboard sound and MB.

    I believe that this is just a fact of life for the MB that I have and the onboard sound I am using. I doubt I'll ever eliminate it. I'm going to try the last two options. PCI Soundcard, then USB sound, but I bet the whirring is entering the line on the MB. The other hope I may have is that by adding a usb sound card, I may eliminate the gain amplified headphone line that I'm using now which can only serve to amplify any distortion I have.

    Best of luck to all who are having noise issues.

    hmm , so im gonna try that one. So i just cut off a piece of the audio wires going to the computer, and ground them the same exact way i did for the laptop right? i never though of doing that but i guess since its not a power wire comin from an inverter or nothing that i can ground them.

    this fourm is really helpful, a lot of people coming to me with suggestions and it is helping me a whole lot to basically try and tone the buzzing down. It seems with every step i do, that i can actually get rid of it more and more, i dont think ill ever get rid of it , but i guess if i tone it down to a bare min then it wouldnt bother me no more. Thanks everyone
