This video shows how to replace a door speaker on a 2014 Kia Cadenza. The speaker busted so I had to replace it. At the time of recording this. I don't know if some one has created a universal speaker mount for this particular vehicle . So you will have to reuse the factory speaker housing. The door speaker size are 6.5 inches. I went with Infinity Kappa 6.5 speakers but any 6.5 inch speaker will fit regardless of brand.
