    System Build Questions Power,USB,Etc.

    Hey Guys, hang in there for this one.
    Ok so Im in the process of choosing a system to put in my car, now I figured I can use a mini ATX board since I have the room in my truck and im looking at Lilliput 7 Touchscreen (Any one have problems with this screen?).

    Now what I want to do is to rip the head unit out of my truck and just use the carputer for radio, cd along with the GPS and DVD playback.With that said heres the chalenge

    I was wondering if anyone has done that, I know I would have to amp the line out of the computer to the speakers, and for the sub, but I read somewhere that this would not work and that you would have to amplify the source for the amp to read it. Has anyone herd of this?
    Also do you think this Is a good idea to remove the head unit completely?
    Any comments are good.

    POWER:
    Also since I will be using a ATX motherboard not the ITX, I will need some more power than the normal dc-to-dc power inverter. Does anyone know of any websites that have guides to building a PS capable of doing like 200 250 watts? Also I have read that lower voltage has burnt out some peoples power supply for the Lilliput screen, I have also seen some pages about how to make some step up transformers of some kind.
    (Anyone who has any input, feel free to post )

    USB:
    I have also seen a site where they cut the USB cable and used a relay to power the USB devices to take the strain off the mobo power supply ( Has anyone done this, if so be leave detals)

    Well thats about it for now thanks for reading guys, any input would be helpful.

    Let's see how many we need to hang on for. I'll bet every one of your questions has been addressed multiple times here...

    Lots of people have had problems with them. Might be defects, might be shoddy workmanship, might be shipping damage, might be user error. I don't know. Xenarc screens generally have a better reputation for quality. There are Liliput owners that are absolutely happy witht he screen choice. YMMV.

    Some people have used a preamp or equalizer to boost the signal from the computer to the amplifier. It could help witht he signal strength and/or quality. Others have gone straight from the PC soundcard to the amp with great success.

    Depends on what you want.
    Here's how I see it: If you're losing the headunit entirely, then the PC plays the CDs, the DVDs, etc. The sound quality may be lessened somewhat (depending on the setup). The PC is going to be more difficult to configure and tweak the way you want, whereas the headunit is pretty much a no-brainer (insert CD and listen).

    You can buy 200-250W DC-DC power supplies pre-built. They aren't regulated, mind you. The Opus 150w is regulated, but it's also less wattage and more expensive.
    Maestro (a user here) has plans available (and a kit for sale, at last check) to make a DC-DC power supply.


    USB:

    Yep. Search around, you'll find it. People also mod their monitors to be powered off the DC-DC power supply and fire up along witht he computer.

    Use the Search tool here, and the answers to all your questions will be revealed.

    Oh, and welcome.
    Have you looked in the FAQ yet?
    How about the Wiki?
