Hi, I'm new to posting on the forum (though I've been reading for a while).
Sorry to re-open an old thread, but it seemed the best place. I've followed the advice here in preparation for adding an Alpine CDA-9886M head unit into my XF - very grateful for this info as I much prefer to use pre-outs.
I've planned everything out and made a wiring diagram. I'd welcome comments and if it helps someone else that's great.
The one question I have remaining is about powering-on the amp. Most head units have this capability. Does anyone know if the factory unit does this or is it a separate circuit?

Nice idea - I've used this approach. Another benefit, if you ever want to add an extra sub it would mean no extra cutting at the amp, just splice in again at the same join.
