help no rear speakers '99 expedition

[BigAlz1]

Hello again all. Here is my problem I had to remove the dash to replace my heater core and broken blend door. Well now I am putting everything
back together I am testing everything before I do. Strange thing is I lost both my rear speakers. I have an aftermarket radio so I bought a wire harness hooked it up to eliminate the factory stereo. Still nothing, pulled door panels off checked speakers nothing wrong with them. So where did my sound go? Is there a clip I have left off somewhere? I called ford they say there isn't any other clip and the local audio place swears there must be an amp for the rear but again doesn't explain factory radio not working either. I think ill just put all dash back together with new radio and go from there. Does anyone know what's going on here?

I would trace your speaker wires down. It could be that one may have been unhooked while replacing the heater core. I would also think to check fuses. Test them and not just look at them. I had a radio that did not work and I spent two months trying to get it to work and got down to testing the fuses. One fuse was not working, even though it looked fine.
If two radios are working. Then I would think of a loose wire or something unhooked. Hooked up differently by mistake.

do you have a mach audio system? cause if you do then you have an amp.
