    Question How to power this.

    Ok i have built this mp3 unit and i am wondering how to go about powering it inside a truck.

    What im running:
    AST motherboard w/ onboard sound and video
    2.1 gig quantum fireball HD
    and a fan

    Im trying not to spend too much money here, as it is more of a little project then anything. From a newbies perspective can you give me info on what to look for (ie. specs for an inverter) or even other ways and how to set it all up.
    Thnx in advance

    Cool

    If the motherboard is ATX, get an (ugh) inverter and an ATX power supply. If it is AT, get an Arise DC-DC converter. See other posts for detail.

    Well You can do few things.

    1. like 'Aaron' says get a power supply (or inverter) and run the power cable to cig. lighter in front or dirctly to the battery.

    2. have a second battery in trunk. (This will add more weight to your car)

    3. You can relocate your main battery to the trunk. If you have a sports car , this will increase the handing of the car.

    yeah right, as if the 2-3kgs from the battery are improving the car handling.
    Before the car i own right now I had a 'sportscar' A Honda CRX DOHC, nearly 800kgs and over 150hp, And this thing would slide away its back when going really hard through corners.

    I put in a bag of cementpowder from 50kgs in the back of the car, and this almost didn't help anything, so I doubt that a simple car battery will improver handling

    2. have a second battery in trunk. (This will add more weight to your car)
    This is maybe an option, but you STILL have to run a wire from the alternator to the battery to CHARGE it, or are you going to get out the battery everyday to charge it in-house. So you'd be better of with a wire and inverter. and not adding the costs of an extra battery. (depends on power consumption in car... but with normal use, one battery should be fine!)

    (ie. specs for an inverter)
    make sure your inverter DOES supply the power needed for the computer... (i.e. don't run a full multimedia-pc with graphics accelerator and all other thingies of a 100w supply, 'cause this just won't work)
    For normal use 150w is more than enough..
    I've seen people telling on their website that the whole setup uses about 30-45w, so 150 is more than enough.... depends on hardware intalled..


    Just my 2 EURO-Cents (lol)

    A Civic CRX is not a sports car. Don't argue, don't try to convince me. The simple fact is that it not.
