If anyone can explain this i would be very greatful. I get home from a long night of drinking last night, park my car, and go to bed. I start my car this afternoon at like 1pm, and drive 5 minutes away to a local bagel shop for some food and coffe. I then sit in my car with my girl, eat my bagel and drink my coffe. During this lovely brunch i have my radio on for maybe 15 min. (i have 2 12' kickers, 4 internal pioneer speakers, and a 400 watt mtx amp) The reason im telling you this is because im curious if it would be the cause. Next thing i know i go to start my car and my battery is ticking.....WTF!!!!!!!!...m s*** just died. Obviously i had to call a friend to come and jump start my car. Anyone have any idea!!! For the record no i didnt leave anytihng on overnight.
