Are you sure it's not under the passenger seat? At first I didn't see mine because the DVD unit for the navigation system is directly on top of the Levinson amp.
Also, e-mail this guy: E. Gus Mancy at email@example.com. He really helped me out when I had an issue with my 2002 Levinson radio head unit.

Green eggs and are tasty.
I just want to say thanks for your help here, I did contact the person you listed and he was a great help, I did find the amp under the seat, ( DAH on my part) and I want to make sure it is the amp at fault, do you have a diagnosing sheet for this.
Is it time for a new head unit? bad Amp?
This '01 LX470 ML/Nav first had intermittent CD, then no CD sound. Now it has no FM/AM/Tape. FM may go on for a few seconds, then turns off. The speakers sometimes "click" while the stereo is completely powered off.
