Just wondering if you can use speakers from another car into my Mitsubishi. Is there a way to buy a harness for the wire that connects to my old one and new one

What is your question?

I got speakers from another car (Audi) I was just wondering if there's a way to use them in my Mitsubishi i know that I can't coneect it because of the harness of the wire is not the same as the Mitsubishi so I was wondering is there a harness to buy that will be able to make this work or what do I got to do because I got a pair of nose speakers and I wanted to take out the infinity speakers
