    Is your battery problem even stereo related? If you are running that system with the car off then the battery will die eventually.

    Be more specific.

    2 Possible Scenarios

    1. Your Battery is shot.
    2. Your Alternator is shot.

    Get your battery and alternator load tested at a local shop. I think Pep Boys or Auto Zone in the US should do this for free.

    What's the rating on your alternator? 1600W peak draws about 133A. Not that you draw all that current constant but it's alot.

    Does your RPM drop and headlights dim when you crank it up? If so, you need a bigger alternator and do yourself a favour and get an Optima yellowtop.

    Then again, your alternator or battery could be shot.

    lol save your money - a capacitor won't do anything.

    Check the battery. Check the alternator. One of them is gone. Replace it.

    A Cap is not a battery, nor will it prevent your battery from dying. If your battery keeps dying then your alternator is toast. Get that tested.

    Either the alternator is toaster or it isn't big enough. Find out how big the alternator is then find out what wattage that amperage can maintain.

    Okie dokie, that's an easy question.
    A large amplifier will put a large intermittant draw on your charging system.
    What I mean is, when you sub is pounding, there is power going to it at say... 40Hertz. So, there must be power going into the amp at roughly 40Hertz, now the capacitors inside the amp will buffer that a bit, but it is still a non-constant draw. Alternators are fairly slow to react to a changing draw, and in the long term, a large draw of that natrure is detrimental to the life of your alternator.
    So, a capacitor will buffer the power a little. Since there is a much lower resistance path from it to your amp than from your battery/alternator, it will provide most of the power to the amp, and then it will place a more constant draw on the charging system.

    I hope my explanation was enough. I know what I am talking about, but I am never really able to answer simple questions =(
