Stereo speakers suddenly stopped working

Hello,

It sounds like a fuse (RDO, AMP or DISPLY) has gone out. but to be sure let's use this guide to check for power. I have included the fuse locations and the radio wiring diagrams so you can see how the system works below. There are two kinds of radios I got both sets of diagrams.

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
