I got the alpine sound system with the all weather sub on my 2017 sport. I'm going camping this weekend and was looking to use it for some music. Anyone have recommendations on the best way to do it without killing my battery? How long can I play the sound system without having the car running?

 

honestly, i'd say a couple hours. the reason i say that is because when we used to go to the drive in movies and hook up the cable to our jeeps, (yes, i'm old enough to remember those), we'd run our stereos for the duration of the movie with no problems.

 

Now I imagine the subwoofer with some volume might take a little more power. Maybe 45 mins to an hour and start it up to charge?
