    Interested to see how this goes, just ordered a screen and in the planning stages of my first car-pc. I already have a decent amount of audio equipment in the car to the point that if i play a 10hz test tone around 30% volume you can see the back seat flexing in and out, behind the seat there is a solid metal plate, then the car battery, some rear-wheel steering computers then the subs in the boot so that's quiet a lot to get through to make the back seat flex the way it does, not to mention the various vibrations and flexing that occurs during normal audio play back.

    Working with PC hardware for 14 years I can't imagine any mechanical hdd is going to withstand that sort of torture if placed in the boot no matter how it was mounted.

    Sound will affect the drive... see these test results for proof...

    That being said, make sure you have an image of the drive and try yourself...

    It's not so hard, I hit 137.5 in a DB Drag competition with just this:
    - JVC El-Kameleon KDLX-30 headunit
    - Rockford Fosgate HE2 12 inch subwoofer
    - Rockford Fosgate 250m Power amplifier

    That was with a 250 watt amplifier so if you're running a 3000 watt and only hitting the same range, it's either not class D or you don't have it hooked up properly. The SQL was really good on it too.

    meter was the same in every car, it was on a stand on the passenger side in front of the glovebox. Engine was revved to 2500 RPM for the drag and it was in a 2000 4 door Cavalier with stock battery/alternator.

    Well seeing as one recent record being in august using an concrete filled Volvo contained a Digital Designs 9918Z 18″ subwoofer receiving 26,000 watts of power from four Stetsom 7KD amplifiers.

    i find it hard to belive that you were pushing that with a 200 anything Watt amp...

    My system is by all means hooked up correctly and the amp is a Class D.

    But you are taking this thread off topic there are plenty of other threads to deate peoples systems, claims, and accomplishments.

    I just have to ask........

    Has anyone actually killed a HD with a subwoofer or is all of this just speculation? I don't see it happening. I've been running the same 160gb 3.5" HD for about 4 years now with no Issues whatsoever. This drive was in a MKIII Jetta with a lowered cup kit suspension, in a modded xbox for a year and a half. Then in my lowered MKV Jetta GLI carputer for 3 years. the whole time it sat 1 1/2 ft away from a JL 12 W7 running on a JL 1000/1 in a ported box. I'm not saying it's a super-monster-*** system but ****.....There's nothing special about the HD or the case it sits in.

    I'd say if your HD died and you just happened to have a subwoofer, it was just that damn HD's time to go

    unless the OP were to mount the hdd directly over a sub and mount it loosely, the spl shouldn't affect it very much, assuming that it is mounted to a firm surface.

    EDIT: i would be very interested in any data anyone has to disprove any points i have made, so far, i have not seen/read anything to justify that a ssd drive is better in a vibration prone install.
    I agree, I have never had a HDD fail from bumps and what not. 2.5 drives are made to be tough, otherwise they wouldnt use them in Laptops. All you have to do is make a good image of your HDD, and if it fails, buy a cheapy and put the image on that. If you really need to go SSD, then get a good quality one, like one from MTron. They are pricey but work h3lla good. I bought a Patriot Warp v2 SSD and that $h!+ sucked @$$. Never buy a MLC based SSD, only buy a SLC based SSD.

    edit-- removed picture..

    excelent points-- my second post was directly related to paulF saying it would tear standard hdd's apart and that he NEEDS a ssd drive.period.

    i don't know what kind of budget danimal has, but thought that if his install was lower budget, there are alot of other things he could put that money towards to build a better pc.

    i think it would be best to leave it at this:

    a standard 3.5" hdd will not (in theory) last as long as a laptop 2.5" drive, and a 2.5" drive will not (in theory) last as long as a ssd.

    but, this is all a theory, and you could end up with a ssd that stops working even before a 3.5" drive should.

    it really comes down to what you can afford. if data loss is a major issue, keep a fresh image in a safe location(s)- reguardless of your hdd selection.

    we are working with electronic components, and all electronic components will eventually fail-it is only a question of when and where.

    This is an excellent idea for any install.
