I got a question, I just recently sold my head unit; but I still have a the wire connected to the battery to the amps. So about 2-3 day's later with out driving my car around, I decided to take my car to school and I notice that my car alarm did not go off or even unlock the door. I went ahead unlocked manualy, and even check my interior lights. No sign of any power in the car or even starting up. I know it was my battery, so I have a 3 year warranty with Sear's and took it over there to check if its dead or not. It turn out it was a dead battery for less then a year, so they gave me another brand new battery. About 4 days later, my car dead again, so I took the battery they gave me back to exchange it and the battery they have given was another dead battery. Now they told me to bring my car in for a test what's draining the battery so fast. I got my car running, took it over to Sear's and have it check out and they said the car is fine alternator is good, starter is good, and battery is good and there was no blown fuse. Anyone know what can be the cause of my car not starting up? Remember, I have a complete sterio system in my car and some people said that if your having a complete sterio system in your car you got to have a bigger battery.

 

It's not the battery that's the problem, it's somewhere in your charging system that's draining the battery. I run a stock battery in all my cars and unless your running some MASSIVE stereo you shouldn't need anything other then the stock. What kinda system are you running?
