Hi there. I have a 2012 jeep wrangler Sahara unlimited. I am looking at upgrading my sound system to the loudest and best thing. One question I have is, if I put a sub, is there a place I can put it where I can still put down my seats and sleep in the back? What speakers should I get? I know not the slightest thing about speaker setup, so please just let me know anything you feel would be helpful. I have the factory nav screen and Bluetooth and CD player and iPod hookup if that helps. Thank you guys!
