I removed the amp and sub and am looking to hookup up my speakers in the car to the stereo that is installed. I have added photos of the stereo and the wire that is currently hooked up to them. I am wondering if these cords get connected to my battery? And how i get them all to connect to my battery if that's what i'm supposed to do, how do i find out which is negative or positive. Please if someone can help me out that would be very kind of you, I do not know what i am doing
