I replaced the stock HiFi amp on my 2008 e90 sedan last month. Had the negative terminal on the battery disconnected then when finished I reconnected it. It wasn't until I closed or opened the driver's door that the rear right speaker noise began. Turned the audio off and on, also started the engine and shut everything off but the static noise keep going. Pretty damm loud too! After 2-3 minutes it stopped without me doing anything more. Hasn't come back.

Hopefully you and I experienced a one time gremlin that won't return.
