Anybody have some audio know how?

My 91 civics audio system is being retarded for real.A few days ago, my rear speakers would cut in and out, like they would be quite, then normal volume.The next day, they were just quiet.Now, the I can't adjust the rear speakers volume, the passenger side speaker isn't playing anything, and the front driver speak is the only one working correctly.Oh, and when I have my ipod playing, I can change it to radio or CD and the ipod music will play along with the radio or CD music.I don't know the first thing about audio or electronics. Anyone have any insight?It's a Jensen head unit with no amp or anything, if that helps.
