Where is the audio amp located in a 2001 740IL?
I'm searching for the amp that comes in a 2001 740IL factory stereo.
Any ideas would be helpfull. The CD changer located in the left side of the trunk. I'm hearing humming sounds from rear speaker(above trunk) when the car is playing music. Also, humming sound continues if i cutt off the car stereo. "Very annoying". I tried replacing the factory speakers with new ones but the humming sound continued, so i'm assuming it could be the amp.
