1987 delta 88 royale problems installing cd player

I tried installing a after market cd player, i bought the harness kit and everything hooked it all up. but nothing comes out of the speakers...i double checked the wiring for the speakers....the cd player is getting power...but i can't get any sound out of the speaker. and when the factory radio was in the speakers played fine...any ideas?

Even tho you dont think its the wiring... it is.
Thats if it is not broken.
