With the truck being 21 years old as well as the original Infinity speakers and amplifier I would suspect that the amplifier has failed or it is not receiving an audio signal from the radio.
Get a printout for the radio and amplifier connectors and make sure the amplifier is receiving B+ battery voltage and a good ground.
To test the speaker wiring from the radio and amplifier connectors you can use a 9V battery to power the circuit to the speaker. You will hear a little pop or a crack when you power the circuit because it will flex the voice coil. This is where I'd start my diag.
