    Newb: power question

    hello all. I currently am planning my car puter system and have a quick question. I have a Cap in the trunk for my amps, and i plan to put the carputer back there also. Could i run the + and - from the carputer to the cap?

    Thanks for the help guys

    Save yourself some heartache and run a seperate wire, fused at the battery. Yes you could, but with current drawn by the amps, the voltage drop that would ensue, and the electrostatic field of the cap discharging to maintain voltage steady...That circuit is just a little too busy to add an essentially unrelated load to it. Noise may also become an issue if you do.
    It's been a while...

    What he said and PC's dont drain much power so it's pointless to need a consistant amount of power from a cap when your Batt will be just as consistant. Have fun

    I recommend an all-inclusive PSU that has startup/shutdown control and battery protection functionality.
    Do you need one? No, not at all. You can use an inverter, as many people do.

    However, there are a number of advantages to using a DC-DC power supply. Read up about them on these forums.
    Have you looked in the FAQ yet?
    How about the Wiki?

    If he likes it and it works well for him, he probably followed the directions in the manual.
