Car electrical system randomly shuts down?
I recently bought a 2008 Chevy Impala about 3 weeks ago. (The electrical system is not in the warranty or else I would take back to where i bought it.) My car first would not start about a week ago. I mean it didn't make no noise nothing and it was like the battery was dead. So I bought a new one and 2 times since the new battery my cars electrical system just like dies out. I would put the key in the ignition then all of a sudden everything goes out i am not even able to start it and the key gets stuck in the ignition. I also never done this before but the engine was really dusty so one day i decided to wash it off at a local car wash and this was the day before my car battery died. Is it possible something got wet that wasn't suppose to? I mean i barely washed it i mainly put it on the engine block it wasn't a power wash it was the engine wash option they had if you ever seen one at a local car wash. (anyways just a fyi i did get a stereo installed about 2 weeks ago before the new battery and i had a amp and sub hooked up but took it out due to my amp messing up. Also I have HID lights installed) Not sure if that might have anything to do with it. My father-in-law who sort of knows cars said I have a short in it due to my stereo i installed. He said its using too much power and draining the battery not sure if there's any truth to it. But my stereo goes off every time i turn the car off. I mean I do leave the faceplate on just simply since I have a alarm and live in a decent area. Please any help. I'm thinking of just putting back the factory stereo and seeing if the problem goes away. One last thing before this i had a 2005 impala with the same set up and did not have any problem at all.
