Interference/Engine/Electrical Noise Help

[KuRuPTioN]

Ok So I had a Kenwood KVT-910DVD in my 02 BMW 325i which did not have this problem. Last week I had a KVT-815DVD installed and now when the volume is high and the song isn’t playing (like silence in the song or ending of a song) I hear this annoying sound. I took it back and the guy said it was a problem with the radio. I took it to another shop and they told me it was the stock amp i'm using. Keep in mind I never had this problem with my last DVD deck just last week. I don’t really know what to do. Anyone have an idea or a place where people know what they are doing I can take it to? I made a recording of this sound the CD is paused with the volume up. The level of noise is proportional with the level of acceleration. Any help would be really appreciated.

Thank you,

all i find is grounding issues. Im using the same ground on similar deck. Also I think this is different because its only when the volume is up.

sounds like alt whine, if its in proportion with acceleration. find another ground or run your ground back to the battery. see if that helps.
