I upgraded the speakers in my Bronco Sport with two pairs of Pioneer coaxial speakers. For the front speakers, I used a pair of TS-Z65F, and for the rear speakers I used a pair of TS-D65F. I also installed sound deadener to the front and rear doors. The hardest and most time consuming aspect of the install was pulling the wires through the wire boots in the doors. If you are not running an amplifier then this step is not needed. The upgrade was well worth it; as the new speakers are much brighter and clearer.
