Radio not working

I used to repair car radios. Check the antenna. If the antenna is open or has a bad ground to the fender it won't put out any sound. If you've got a ohm meter check to make sure your speaker isn't open. It should read 8 ohms accross the speaker connections. Also when you touch the connections with the ohm meter you should hear a clicking sound from the speaker. If you don't have a meter you can use a battery and a couple of wires and go across the speaker connector and listen for the click. If you can hear the click the speaker is good. The final thing would be the audio output transistor on the side of the radio but that might be something you might not want to try changing if you're a novice at electronics. Good Luck
