factory amp diagram 98 escort zx2

Amp quit one day can adjust everything but has no sound.  I have tried replacing the amp and the stereo they are all still stock not an aftermarket stereo.  I was wanting to find a diagram for the amplifier wiring so i can diagnose the problem.  If you have any info on what might be wrong please let me know, thanks.

You should get a volt meter and look for a wire that has 12 volts on it at all times, then look for a wire that has either 6 or 12 volts on it when the radio is turned on.  There may be a blown fuse.

Check for power at the amplifier.

If I had power to the amp wouldnt it work? Not for sure, checked had power. Does anyone have an a idea on where to find a wiring diagram for the premium sound amplifier?  Im needing it for troubleshooting my wiring in the car.

If the amp had power and it was not broken, yes it would work. If the amp fits the description below, there is a good chance it is broken. They are not the most reliable things out there. I have never repaired one out of that particular car, however the Mustangs, Expeditions, explorers and some lincoln vehicles use the amp described below. They break regularly. Is the amp silver in color? Does it have 4 torx screws mounting each end cap to the amp? Are there 6 or 8 torx screws mounting the bottom cover?
