    with 8 15" subs is there even room for a carpc? You might need a sound proof box to house you carpc in to stand up to that bass

    i have a volvo wagon. ive considered that, but to cool it air has to get in,.....where air gets in, pressure gets in. Ive also thought of enclosing it in a bandpass box, and flip the polarity of an 8 inch woofer in there.....maybe cancelling some of thr pressure......ant ore thoughts.....thanks again y'all...

    your talking about massive vibration waves, so hmm i think it will not work and be too expensive to make a shock proof box for a HD, esp at the levels he is talking about, i doubt there is any even data on HD's with those levels because they are beyond normal operation or what can be expected, your best bet is SSD just get the solid state HD's and i dont know but maybe a mirror image of your current partition might work with the key on new hd... assuming all the other hardware is the same

    these vibrations im sure you can feel even quite a bit out from the car, I would assume… I never experienced something like that, but it could be something to that of concert sound system packed in a very tight area at close range, I doubt any HD would work, the vibrations would just transmit themselves through materials, and your absorbing system would just go into a cyclic state and eventually cause the HD to fail or hick up
    As mentioned by others and me your only bet is solid state hard drives they are somewhat cheap now depending on the size and the performance you want

    I was just being sarcastic... obviously a sound proof box would be a heat issue. The only way to get around that would be to use a water cooling system but that is just impractical for automotive use. I thought about it when I first got into the carpc thing and found a bunch of threads explaining how its unstable and draws too much power.

    A SSD you would work for a hard drive most likely but the motherboard and stuff is still vulnerable to vibration issues in some cases, especially with the amount that 8 subs will produce in a car.

    160 db, nice. Thought I'd drop my two cents in the bucket. I hit a 145 db at about 140 hz, I was using a sine sweep so don't quote me on the hz, and had minimal trouble, only locked up once.
    Although I did notice that particular old setup didn't like 135 hz....guess that was the brown note for the HD or setup, cuz it would crash it almost every time and not necessarily at the extreme higher SPL's.

    those are awful high htz. you must have a one note wonder ported box. if not screw the sweep.....your waisting juice......start lower, like 60-30.....ty for the intel.

    i would say you will need a mobo that does not req a large heat sink, as that will be too much stress on the mobo, with those vibs, i would go with something that will req a small heatsink, best bet would be a mobile chip, if possible, and also the heatsink should be designed in very sturdy way to clamp on mobo, you might end up using something under the mobo or a lot more locations then just thte 4 screws on the miniITX mobo, to support and dampen the vib. on the mobo, as im sure over time you will develop some failure due to fatigue

    i would recommend a all in one mobo, that will be your best bet, not sure if you want to use copper or AL, for heatsinks, but you want minimal weight but best efficiency as well as least thermal given off by the components as possible

    this doesnt mean you have to use a low low power mobo/cpu/gpu combo, you can always get a decent mobo and a cpu that you can undervolt and underclock so that you have a mobile cpu from a desktop

    all i can say is that you need to put a lot of thought into the design for this carPC, if you want it to last or even work in those conditions, these are quite the extreme and not norm conditions so ya

    i'm not entirely sure about this... but wouldnt 8 15's be creating a gigantic magnetic field? maybe after too much exposure the hd finally wears out?

    i dunno... just a thought...

    OMG, thats too funny. Okay typing late at night is very, very bad let me remove my retartd cap now.

    Those should read 40hz and then 35 hz for the brown note. And no the box is actually quite musical, as always, its a balancing act if you want loud and musical. I was not trying for and nor do I have a one note wonder, and those are cool for comp.'s but I am not much into that anymore.

    As for homeboy's setup, 6 15's is pretty extreme, and yes cool. The more solid state you go the better. If you are really into the one note or SPL thing you could easily make the carputer removable like they do with the car stereo's. Run like ITX or smaller and just give yourself extra wire and make it removable and run it outside the vehicle for comps.

    Or you could mount it under the hood that would be isolated and a little toasty...shorter wire runs are better anywayz right???
