This is how to install new door speakers in a Kia Rio 2012-2017. The speakers are being installed in the front doors but it's the same thing for the rear door speakers. the speakers are Kenwood KFC 1666s Sport Series 6.5 inch 2 way speakers. I also used a Metra 72-7303 Speaker Wiring Harness and Scosche SAGMEQ656 Speaker Mounting Brackets. All of these parts are available at Crutchfield.
