No, you don't need a new battery. You need to recheck all your wiring. I don't think it's your amp that is doing this. You battery doesn't supply the voltage (given your alternator is powerful enough to supply every drop of power for your car) to your amplifier. If your car was started and it just shut off it's got to be something other than the battery. YES, it may be dead, but just replacing the battery, doesn't mean you'll fix your complete problem.

hmm ok so tom. il recheck the wirring..that may be it becuase when i put it in park the engine shuts off and the battery light comes on..but the car stereo, lights, headlights and basiclly all the other electrical iteams in the car are still running and working..it just turns the engine off in park..

It may be a transmission problem, or the alternator MAY be having problems and not able to produce enough amperage to run the car, at idle speeds. Start the car, put it in park and the rev the engine before it dies. If it stays started, it would be the alternator, most likely, but not definative.

Sounds like a wiring problem. Did you try to boost it off, to see if it drains it again?

boost it off? what iv been doing latly tohught was actually messing around with the gains and the frequency...trying to make it sounds right..maybe i made a wire lose? ionno.

He was talking about boost it off with cables as you have a dead battery.
