it could be that you have the wires hooked up wrong and the amp stays on while you shut the car off, i dunno why but that happened to my freinds car and it killed his battery. if you do plan on getting a capacitor, you need to buy it based on this. for every 500 watts, get .5 farad. example, if you amp is 900 watts rms, get a 1 farad cap.
