I have a 2010 Lancer Ralliart and every now and then, on the colder mornings, my battery is completely dead. I have a 1000watt amp in the car for my subwoofers (With a large capacitor), a viper 5901 remote starter, and HID's on my highs/lows. I had the battery tested at an autozone and they said it was fine. Could it be that I just need a higher capacity Alternator? Or could it still be that the battery just cant hold a charge?
