    Do some digging - its possible to mod an AT power supply to supply 13.5v at 20amps. use in conjunction with one or several batts and there you go. Very cheap way to do it

    yeah figure on how many watts youll be pulling, eg 200w rms amp 200/applied voltage (12v?) 200/12 = 16.67A, so Im sure youll need a fairly large psu if u decide to go this route

    I said a modded AT psu - all the power gets dumped into the new 13.5v line.

    Running all/part of your auto soundsystem indoors

    Sure, you can run your system off a battery charger - BUT, you must also use a battery too! That is, you take a battery in working condition to run your system but run the charger during it's use and afterwards to charge it back up. You may encounter some buzz from the battery charger which requires filtering. Better to get a dc power supply to recharge the battery, or one big enough to run the whole system - 60-100 Amp or so. Subs take lots of amps to push at low freqs.

    You could also use a ATX powersupply. To turn one on connect the green wire to one of the grounds.
    Check to see the amperage of the +12v line is sufficient to run the amp if you go this route.

    silicon chip october 2003:
    20A/13.5V supply from an old PC.

    is that what u read doig.
    so if we follow guitar333 example 200/12 = 16.67A
    20A is enough
