hiss from stock amp??
 

took my 06 SS into the dealer the other day for a few items. One thing I noticed is that my 8 speaker 200watt radio will emit a lite tape like hiss from the speakers; can't really hear it when listening to music. When a pause in audio, during a pause in DJ talk, or volume turned up to first notch when audio is real low - you hear it; turn volume down to "0" and no more hiss. Any one else experience this in their stock radio? Dealer says it's normal. If I have a chance i'll listen to a new Monte next time i'm at the dealer.

thanks!
