If I bump my system with my engine off (say, at a sound off or car show or something), how long till my battery dies?

not soon after you kill your amps.

Battery? Are you actually pushing 1000 rms? Wiring? Big 3?

Don't get me wrong, even if you put up all this info, I wouldn't be able to answer, but all these things will probably be factors. Make it easier for the guys that might know.

It depends on a lot of factors. Best bet is to get a voltmeter and turn your stereo off when the voltage dips below 10.8v when no music is playing, your car will barely start but it'll at least start.
