need help with car audio ASAP

I bought a car and didnt realize tht it had aftermarket system in it. Well i knew the front speakers were different but i didnt know if i even had rear speakers cause i never heard them. So it was nice today I decided to clean the car out i open up the trunk and a found an amp goin to all the speakers, It i was a decent setup my buddy told me. The speakers front and back are FOCAL and i dont know why or wht the heck to do to even make the rear speakers work. I really dont get into sound systems so i called my buddy and he tried somethings and they still dont work. If someone doesnt mind to take a look at this or give some advic what to do lemme know please.
