Question
Couple days ago I had the radio on I got a short static sound out of the rear speakers and then all of the sudden the volume maxed briefly. I turned the radio off and turned it back on, it played music normally for a couple minutes, then same problem happened. Now all I get is short busts of low volume static every five minute while radio is on. When I turn key to off position, radio does not turn off. Any help would be great! Thanks in advance.
97 Astro Van with premium tape deck with preset tone.  

Answer
There are a couple of possibilities that come to mind.

ONE:  The 12v line from the ignition going to the radio unit is loose and not giving a good connection to the radio (or at the ignition switch connection!).  Correction is to check the wiring/lines and tighten or reconnect.

TWO:  The unit has internal circuit failures.  Needs service and troubleshooting. Probably, if this is the case, a new/replacement head unit would be less expensive than a repair.

Hope this helps.
