head unit on, no sound

[go-go-gomez]

so i took the truck in the woods to pull some firewood, turned the radio all the way down on the way in, then on the way out i tried to turn the volume up and nothing. i know the radio is on, i can change channels, turn from AM-FM-CD, just have no sound coming form any of the speakers. I did replace the door speakers with infinity kappa's, (about 6 months ago) but that's it. head unit is stock. any ideas why this is happening? what should i be checking?

thanks.

Do you have an amp running your speakers or just off the head unit?

they are just run off the head unit, by the way this is in my 01 1500.
