Hissing sound when car is turned off (Speaker)

[SIX SPEED]

Yesterday I noticed a hissing sound coming out from my left top dash speaker while playing music. When I turned off my car it still was hissing a little loud. I will not turn off at all... I looked for any loose wires but I could not find anything... I knew if I left it like that in the morning I probably would not have any battery juice to start the car so I unplugged the 20 v fuse out from the car and it stopped.

This morning I replaced the fuse back in again started the car and no hissing sound. But after 2 minutes it came back. But this time I just tapped the CD deck softly and it went away...

Could it be that my head unit is going bad?

This is annoying......

Well I think it could be my head unit (maybe) the sound came on again for like 2 seconds then it went away... my car hit a bump and thats when it came on..... it's weird....
