Strange happenings with stock deck
 

I think my stock stereo is possessed... :(

I start up my car. While car is running, I set my stereo controls to how I like them(bass and treble). I resume listening to music until I get where I'm going.

I turn the car off.

On the next start-up. My bass is set to the max. But, if I push the button to look at my settings, they're exactly as I left them. If I turn the knob on ANY setting(bass, treble, fade, balance) the bass is reduced, and back to normal.

But, I HAVE to push and turn the knob every time I start my car. It's kind of annoying. Anybody have any idea what's goin on here?
