It was already from the beginning. I got this car with the dual battery installation around a year ago. As mentioned I thought it would be the second battery which supposed to get charged when I run the engine, but gets disconnected from the front battery if the engine is off.
I kept the front battery disconnected, which then switched on my Amp and sub woofer, which I thought this would be the root cause. However, I disconnected the battery in the back now and still the front batter got drained.
