A bad battery or voltage spike can cause the audio system to lock up, but we need to determine whether the radio itself is operating.

Does the radio display turn on and respond normally? Also, do you have sound from any source—CD, AUX, Bluetooth, navigation prompts, or warning chimes?

Start by performing a reset:

Turn the ignition off and remove the key.
Disconnect both battery cables, negative first.
Hold the disconnected cable ends together for about 30 seconds—away from the battery.
Reconnect positive first, then negative, and test the radio.

If it still does not work, inspect the audio-related fuses in both fuse panels using a test light or meter; visual inspection alone can miss a blown fuse. Depending on the equipment, look for fuses labeled AUDIO, AMP, MULTIMEDIA, AVN, or MEMORY. Most of the time if the fuses are good the radio itself is bad.

Other than this sound nothing. What are the chances the amp went out at same time the alternator did. Where is the amp on this one?

Also, there is a parasitic draw that I have not yet tackled when battery is left connected not sure if it's related. I will start a new question on that one

There are two kinds of radios, one has an amp one does not. If it has an amp I would check the AMP fuse in the fuse panel inside the car. The clock spring may be bad as well. I have seen this cause the radio not to work. Here is the location of the AMP if it has one. Double check these fuses as well.

Yep, lets see if any codes are in the system, it can be the clock spring that has gone bad.
