    You could use a switch mode power supply to setp up the voltage.
    There is no combination of passive components which is going to give you what you want.

    More complicated that it's worth. It'll be cheaper just to buy or build the proper DC-DC power supply.

    what are you trying to power up ? more than likely you can feed it directly off your car and it will be fine - it just depends on what you are trying to power
