Radio not working

Ok - I pulled my stock AM radio after it cut out about 5 months ago. It's getting power just fine to the set, and even inside it there is power registering. But no sound. I'm thinking it could be the speaker - although I'm not sure why it would be (it only had 39k miles when I bought it, and I daily drive it about 70 miles) - it is almost like new inside.

Any other ideas on what to check. I noticed the wire inside that connects to the speaker is not getting power, but I'm not sure it is supposed to.

Thanks for any ideas here.
