I checked the back of your 8003,there is input for R+L(2inputs)
centre(1 input),R+L surrounds(2)+1 sub input.
Sometimes the back of any receiver the lettering is very small and rca inputs very close together.
Type in marantz 8003 on your computer and you will see them.
Or perhaps the manual has a picture or diagram of the back.
I have sometimes inputted into where I should have outputted.
