I'm getting to the point in my install where I'll start wiring in a few days. I have read every single thread here , and information in other places, about doing rear fill using L-R, but I still don't have any definitive answer.
If we are trying to do the Haas effect, do the rear fill speakers (with the assumption that you have more than one speaker, in the doors or in the rear deck) need a "stereo" signal, different signal for each side, or can you use a "mono" signal for both sides?
Here's the system diagram I'm "planning" to use, including the connections for rear fill. Will this "work"?
