One thing that I have already tested is that it is not a true line out. Which in a way is alright, since the volume can still be controlled from the remote. I keep the player and amp in a courier bag normally anyways, so the remote is what I use when moving around. This hack will still have the audio skipping the stuff in the remote head. No idea yet if it is even skipping the internal amp:

edit..... whats with the angery face? I didn't put it there, and can't remove it....
