I managed to kill my battery in my car after playing music for a few hours

Odd...

My player will quit from low voltage before the battery is so low I can't start the car. Of course, if I ignore it the amps will still be draining the battery with eventual unhappy results.

But, I guess that would vary from car to car. Some starter motors will turn the engine over at lower voltage than others. I guess mine will work at 10-11 volts, which I think is the threshold where the empeg quits.
