Hi BING38RT and welcome to the Ford Fusion Club. I would recommend you call Crutchfield and ask them: Crutchfield: Car Stereo and Audio, Speakers, Home Theater, Pro Audio, TVs
They have an extensive database, great customer service and installation experts, and should be able to tell you what you need to accomplish your project. Then you can either purchase from them, or shop around for better prices.
Let us know how you make out and good luck.
