Radio won't work.

What is your question?

I don't know why, but the radio won't work. I thought it was my previous radio, but I guess not. What can the problem be, checked under dash didn't find a 23 fuse checked in my engine fuses aren't blown either. If its a wire that blew or shorted, where do I go to get it fixed or what to buy to fix it myself. please let me know. It sucks with no radio.
