Great post I really appreciate it I am going to upgrade the head unit this weekend to a pioneer im also going to add a jbl amp and upgrade the speakers to infinity speakers. My buddy owns a shop and told me to stay away from the kicker plug and play speakers offered to us owners. I am excited to see how they perform and will do an upgade. I may do a jbl 10 later with those custom subwoofer enclosures that sit on the back corner essentially over the wheel well in the trunk. When you upgraded the head unit did you lose anything as far as display option/functionality from the small video area above the head unit where the boost etc is displayed?
