nah it doesnt have any subs or anything that would kill the battery just a couple of infinity 6x9s i just put in like 2 days ago. but yeah. anyone would know leaving your headlights on for ten minutes shouldnt kill your battery. the car has nothing extra wired to it other than the door speakers. its bone stock. but its obvious the owner before me was messing with the wiring cause some stuff was hanging down behind the radio i had to tape up. but thanks for the suggestions. ill try it.
