snap out an interior pannel, remove 4 screws, disconnect wires from the car and I'm out.

Underseat installs really worry me. There's SO many things that can get under there...no matter how careful you are....

I know I have seen the thread discussing this...truth is my favorite spot was the center console but I got dinged too many times at shows for the outershell of the center console (the oem shell) moving no mtter how much I braced it. I have had the computer under there for 2 years now, all the cabling is routed under the carpet and blocked from the front and back, the hardrive is suspended and protected by the oem metal bracing of the seat. No water, no kicking, no catching of wires...etc. (It even survived an accident I had in my 04 Mazad6 when someone turned in front of me when I was going ~35-40mph. Both Airbags deployed and all)

I can understand what you are saying ..but you can never plan for everything. It's an ongoing battle.

I agree, mounting your pc under your seat is a no no. I've had friends spill stuff too many times.

I don't want to have to gasp everytime someone gets in my car with muddy/snowy boots. (well I do anyways, but carpet is alot easier to clean than a pc is to replace)

Get better friends. J/K

It's not a problem in my car. I am not going to debate this with anyone. Mounting it under my seat met my needs. My computer is inside a solid plastic case that if water got into it then I must have drove into a lake and then I would have even bigger problems.

Every car is different and I thank you all for your concerns.

haha

Yeah i tend to get really ****ed off when they do that garbage. Man is it infuriating. Have a little courtesy for another man's vehicle..

Don't worry we know we can't make the decision for you. We just want to make sure that you know the risks

It seems like you know them, and have addressed them as appropriately as possible.

I was an installer for ` 2 years for Tweeter.

You have to learn what to do and what not to do real quick or you always end up fixing your own work...or others.

something i found interesting:

http://www.adriansrojakpot.com/Speed..._Guide_02d.htm

not sure if our boards have this option in the bios but (from linked page):
Spread Spectrum

Options : Enabled, Disabled, 0.25%, 0.5%, Smart Clock

When the motherboard's clock generator pulses, the extreme values (spikes) of the pulses creates EMI (Electromagnetic Interference). The Spead Spectrum function reduces the EMI generated by modulating the pulses so that the spikes of the pulses are reduced to flatter curves. It does so by varying the frequency so that it doesn't use any particular frequency for more than a moment. This reduces interference problems with other electronics in the area.

However, while enabling Spread Spectrum decreases EMI, system stability and performance may be slightly compromised. This may be especially true with timing-critical devices like clock-sensitive SCSI devices.

Some BIOSes offer a Smart Clock option. Instead of modulating the frequency of the pulses over time, Smart Clock turns off the AGP, PCI and SDRAM clock signals when not in use. Thus, EMI can be reduced without compromising system stability. As a bonus, using Smart Clock can also help reduce power consumption.

If you do not have any EMI problem, leave the setting at Disabled for optimal system stability and performance. But if you are plagued by EMI, use the Smart Clock setting if possible and settle for Enabled or one of the two other values if Smart Clock is not available. The percentage values denote the amount of jitter (variation) that the BIOS performs on the clock frequency. So, a lower value (0.25%) is comparatively better for system stability while a higher value (0.5%) is better for EMI reduction.

Remember to disable Spread Spectrum if you are overclocking because even a 0.25% jitter can introduce a temporary boost in clockspeed of 25MHz (with a 1GHz CPU) which may just cause your overclocked processor to lock up. Or at least use the Smart Clock setting as that doesn't involve any modulation of the frequency.

I wouldn't worry about it too much Jan. If you want build a cover that attaches to your seat rails so when the seats are all the way back nothing can fall under the seat. I did this for cosmetic reasons when I extended the seat rails in my car about 7". At that point you could even put a small removeable plexi window something like that. You can also put a panel behind the computer so toes and whatnot from someone sitting in the backseat don't bother anything when the front seat is all the way forward. Then just insulate the case by putting a sandwich of wood/foam and whatnot between it and the floor.

The mounting the HDD under the seat as posted earlier is a pretty trick idea.

Now back on topic

Her computer is not under her seat, nor is apparent she wishes to put it there. She was suggesting that someone else not do it, if anything...

Hehehe. Thanks. And its in a removable 5.25" enclosure. I just pop it out and go inside pop it in my home computer and load up more music/audio software to install later..etc.

Scott_fx-
I was always under the impression Spread spectrum was similar to what 900Mhz/2.4ghz cordless phones used to reject noise/interference. Would the Spread Spectrum or Smart Clcok feature help reduce USB DAC jitter? I am pretty sure the M10000 ITX board has those features..or at least the Spread spectrum feature.

I wouldn't recommend it either unless you really plan it out. I agree the safest place is in the trunk. But then you have other things to worry about. I wish I could find that thread again. It was a good read.

A lot of what we are discussing has been covered here quite some time a go. This should help out some though.

sweet find!

I'm kind of swamped with other things right now and it looks like it's going to take a good deal of reading to fully understand it.

Am I correct in my initial understanding that this guys set-up will do EVERYTHING that we're needing and wanting?

Is he saying that he ended up needing a separate computer just for the XO function and another for all other processing functions as well as video stuff?

I'm planning on spending a good deal of time reading through it all, but I would greatly appreciate a bit of insight here....lol

RedGTiVR6 · 11-10-2006, 09:59 AM

Ok - so I've read the first 6 pages or so....the thread is a bit dificult to follow.

I'm going to see if I can post up over there and ask a few more specific questions.

turbocad6 · 11-10-2006, 11:24 AM

my first thoughts along these lines were that it will be processor intensive... my second thoughts were to use a dedicated machine for this, & then another as the actual carpc...

I mean the alpine is a dedicated box, so this could be too... a kvm could keep this managable through one screen... I don't know if I'm the only one who would consider multiple machines though... I have 2 motherboards going in my minivan right now, one for front & one for rear... adding a 3rd wouldn't be that intense for me....

I'd be afraid trying to run everything on one machine will cause issues, maybe a really fast dual core with a system that can take advantage of this, but I would rather do independant pentium m machines.....

so how crazy is running a dedicated machine for audio processing? would anyone else consider this?... imagine if it could run on linux... it could be kinda like the alpine in the end, BUT with everything we'd want... best audio quality with pc interface.... is this a consideration? I don't know enough about linux to do this, I guess a stripped down xp machine could do this well too.... maybe an xp embedded solution.....
