Front two speakers no audio?

I would check the front to rear fade adjustment on the radio first. If that is okay, it sounds like the amplifier inside the radio is having a problem and is not working for the front to speakers of the system. If this is the case, I would replace the radiator with an aftermarket unit or a used stock replacement by searching Ebay. Here is how to change the unit out. Check out the images (below). Please let us know what happens.

anything?
