Problem with Pioneer deck
 

I just put my Integra back on the road after the winter and the volume for my stereo has started fluctuating, the volume will go up and down on it's own, it will do this when I'm parked and driving. I'm pretty sure it's my deck as the volume of the speakers and subs will rise. I was hoping somebody would have some input for this problem, thank you.

was youre deck sitting in the car the whole winter as well? Ive seen this before, the potentiometer's contacts will fail or corrode or w.e and then it cant govern the sound properly. Its not a common problem but it does happen. Hopefully its something simpler, otherwise you will need to purchase a new deck.
