Confused on how this audio setup is worked
I am not sure what this product is since it was here from the previous owner of the house. It was installed through the wall so i would like to see if I can use it since replacing it would be extremely difficult. This is what it looks like.
it doesnt have a main console or any other ccomponents besides the left/right for front and rear (so theres four pieces in total.) Which makes me think that either the previous owner took the main console with him or this is setup just for audio.
The other side of the connection is using av cables. It has 2 left and 2 right
So the main question is how do i make it work if it is just for audio or is something missing?
