Just purchased a new RBZ from a 2014 Jeep and I'm wondering if the front usb plug on the face will let me stream my music from my iPhone or if I need something else. I'm also interested in upgrading my speakers. I have the 7 speaker infinity sound system in my 07 and I want more out of it I have upgraded the speakers in the past but it ends up sounding like a tin can due to the upgraded speakers sounding so crisp with minimal bass. My last jeep had two 12's in it and I miss that but there's no way I'm off-roading with those in the back again and I'm not upgrading the HU to anything besides stock.... Any ideas?
