Stereo w/no sound

[Joe Explorer]

Hi, Some years back I had an alpine installed in my 1992 XLT explorer. That system went out. I went to put back in the stock stereo and they clipped off the whole plug. They only reattached some of the wires. I went to the junkyard clipped off a plug and reattached all the wires. Lights, radio buttons and everything works except the sound? On the back of the stereo there is an additional empty plug slot but I don't see another set of wires that would go in there? I'm thinking the amp wire is cut some where but I cannot tell where? Any other ideas or suggestions? Thanks

i think your truck has the premimum sound system there for you have a built in amp you have to ither bypass the exzisting amp or tie into it personaly i am using the factory amp plus the head units amp.
