did the Audi Bose actually want speaker level inputs?


To be honest, I don't know, I spent a couple of hours on my back, in what, in a TT is a very confined space, thought, I can't figure out these connections and took it to the professionals!

If you are right in your diagnosis of the Benz, however: This can probably be solved by installing a small amp across the ignition (Here, you can get them as a ready built compact package from Maplins), with a simple 2gang pot to adjust levels
