Now that I have had a chance to listen to the new Eclipse, I have noticed there is now white noise that was never there before. With the ignition off, regardless of the source, with the volume fully down and every last option either flat or disabled, there is a noticeable white noise, that is present throughout 1/3 of the volume control, until the music drowns it out. While driving, there is absolutely no ignition noise, and the white noise doesnt increase during acceleration.
When I asked the store techy about it, he said a bit of noise was normal. I asked him if my old Sony was abnormally quiet, since it never produced any noise at all, and he basically walked away, so I guess I'm on my own.
The only thing that has changed in the system, to the best of my knowledge, is swapping out the H/U. Any suggestions would be great.
