Why did my front car speakers all of a sudden quit?

How can I get the front speakers of my car to work or what's wrong with them?

• I have a 1988 Oldsmobile Cutlass Ciera with the original stereo which is a Delco. The sound system works beautifully except that ever since I have had the car, the front speakers haven't worked. They don't cut in and out but rather it's like there is no connection to them whatsoever. I've checked all the wiring and the speakers are plugged into the radio in the right place yet still there is no sound out of my front speakers. I've even set the fade to just solid front, still nothing. Any ideas what might be going on and how I can fix it?

• Answer:

  Its either one of two reasons your speakers arent working. 1: The head unit has failed and although its still working your front input isnt working. 2: You speaker wires arent installed correctly or seperated.
