    Post ready to start

    I'm ready to start my project, i've been dreaming of having all the conveniences of a computer on the road.

    My main goal is to have the ability to play mp3s + movies. I've talked to a few people stereo guys in town and one told me that it's not worth doing since the ground loop noise or something will be to high. He is saying i'll get all types of interference since the audio source is coming from a computer.

    What are your guys experiences with playing mp3s in your car. I've got a pioneer deq-7300 with image dynamics 6 1/2s up front + pioneer 6999 6x9s in the back.

    Another concern of mine is i plan on having to 12" subwoofers back there real soon, how is that going to affect the computer since i plan on having some serious bass?

    Lsstly can someone tell me what i need in order to run a computer in my car. I want to first hookup the power source and hookup my desktop just to see how everything will sound.

    You have pioneer 6999's cool cus i have th very same speaker, what do you think of them, rather nice sound i think.

    Sorry i just have never come across any one with the 6999's before.

    as for your questions:
    1. If you ground every thing (to the same common ground), there shouldn't bee too much noise, if there is a noticable amount of noise, just a ground loop isolator (from radioshack)

    2. Subs shouldn't really kill your copmputer, just I would tend to keep the hdd away a little, just to be on the safe side.

    3.To power the unit, u will need either an Inverter, (dc-ac converter) or a dc-dc converter (better, will also help elimiate noise)

    Just read the forums, and use the search function, and you will find that all these topics have been discussed previously

    Ground loop noise can be a problem, but I haven't personally seen it (Grounding the case to the car worked for me), but the solution is usually as simple as a ground loop isolator from radio shack.

    It sounds like your existing audio setup is more advanced than mine, so you'll probably have little problem integrating the sound components.

    I'm in Austin too, so if you want some help, or just to show off, I might be able to take a look.

    Likewise, grounding the case/PSU works fine. Try to aviod ground loop isolators.... as they say, prevention is better than cure...

    hornet: the 6999s sound great, can't wait till i get an amp, they distort a little at really high volumes.

    Loreleiguy cool you live in austin, i'll probably need your help dude, if you don't mind.

    What i plan on actually doing is building a custom case very similar to maveric has done.

    In a case like that would i ground the ps? Also what would i ground the mb to since the case will be acrylic?

    If there an faq on building a custom case if so i need to read it badly.

    Ground both it wont hurt.... although most motherboards i have used ground back through the power supply plugs anyway.... so ground the PSU and you ground both...
