today i noticed that when my car is parked in the garage and it is extremely quiet, it would seem that i can hear the "mechanical" noises that are produced from the deck from my speakers. Even if i have the volume at zero, when i am skipping tracks, or the deck is trying to find a track at random, i can hear the noise that the deck makes through the speakers, it is VERY faint however. There would be no way that i can hear this when the car is running or if i was parked outside.

there are absolutely no engine noises amplified through the speakers.

is this normal?

thanks
J
