    Actualy, I think it did get al ittle alternator whine in there along with the hard drive thinking. So yeah, it does. Sorry, missed that question.

    Otherwise never had an issue and this is with onboard and external cards? Then again i have a lot of luck with electricity ... i should be dead at lest 10 times over...
    haha, well with my bad luck maybe I should never play with elctricity.

    Anyone have an opinion on grounding directly to the battery since my carputer is sitting right next to it?

    you may want to just go with a power isolator between the battery and the carPC then. Just make sure it can handle the wattage.

    if the distance between the computer and the battery is less then the distance from the computer to a grounding point then yea give it a shot.

    being that your carputer is next to your battery- yes, i would connect it directly to the battery.

    the idea for having a secure chassis ground is mostly because most cars have the battery in the front, and most aftermarket electronics go in the trunk, and in order to run a ground wire back to the battery in a normal car, you would need to increase the thickness of the wire a couple of gauges to compensate for the extra cable length. but being that your battery is right there, it would not be a issue.

    using a silverstone DAC and a ground loop isolator ..works very well.

    only better solution i can think of is using a digital out and and amp that has digital in...eliminates all noise.

    Alternator...

    Maybe his alternator has a bad diode... Sometimes a alternator can go for a long time before failing completely, a bad diode will let in AC current into the vehicles charging system and will of course cause noise problems.

    Try to get the alternator tested if some symptom arises, replace with high quality oem.

    Always try to cut your problems from the source, and some testing will save you money along the way...

    Definitely!

    I have a somewhat older VIA Epia-SP mainboard, with an 800mhz cpu,
    and an integrated multichannel soundcard (Realtek).
    Actually, I can set it to multichannel or have it set so I have some extra inputs..

    I use regular quality RCA's with homemade adapter-cables (mini jack -> RCA)
    so I didn't have to cut up the original cables and I'm able reconfigure it all quick and easy.
    The speakers and the amps are mostly JBL branded, but the cables are just the
    regulars from a car-hifi shop. Monster(tm) was way too expensive and the budget
    cables looked way too thin. So we went with the middle class.
    But there are no sound quality issues in any way, nice ultra low frequencies with some
    punch and crystal clear high frequencies (if the mp3's are compressed correctly ofcourse).

    But the ability to control each channel and each frequency is just awesome!

    Ah... I replied way too late I see
    It's a different issue I see..

    I had noise problems in my car a few years ago.. Something with the grounding of
    the engine and the alternator or something.. They (audio-shop) advised me to take
    care of that by extra grounding of the hardware and installing expensive power and audio filters..

    I never did that, I just turned up the volume a bit
    Nah, j/k, my car got replaced before I got to that and never had an encounter with that
    rattling alternator noise again. (I never got a Mitsubishi car again after that)

    Not much of help here I think.. Maybe you can visit a car-hifi-shop and ask for
    these kind of problems.. I'm sure it isn't a unique case.
