well I installed a custom fit sub in my port locker and I really think If I put an additional battery in there it would take up all the space I have left up there. I run a 750 left rear, a 400 right rear so if I did move it I would look at the back right. I always have everyone sitting on the port side. I dont know, just a thought I figured i'd voice. I figured it I have all the storage I'd ever want if I moved it.
