for all of you people who have the JBL deck in their sport or limited, there is a harness to change the head unit and use the stock speakers. Today i got my tints done on a 05 sport and i was talking to the guy because i wanna change the deck and put a 4 channel amp and put in some nice components since i couldn't use the stock speakers and the stock amp, thats wha told him. However he showed me in his book that there is a harness that lets me change the deck and still have all of my stock speakers.
