I'm tired!! I'm thinking the radio wiring stuff is in
the W126 service cd-rom. I'm not sure if this old
amplifier stuff is still available or not. I don't
recall ever selling any of these components. They must
have been really good parts! I remember when they came
out. Decent sound at the time. Heck, I remember a new
220D with one speaker in front, and that was an
option. That car was under warranty when I started
selling parts for MB. Look me up in two weeks and
we'll find out more, or you can send in an inquiry
through normal channels,
