That is sort of the way that I went.
I know that it seems really similar, but the speakers are at 90 degrees (straight to the side) of the listening area, and not the front of the seats. This is how all of the big names show it. Even or behind where the head would rest on the seat, and not in line with the front of the seating area.
There are very few diagrams of what to do for 2 rows, and most of them just put the second row behind the first, and bump the rear surrounds back, but leave the side surrounds "as-is."
I too wonder if a second set of surrounds would help, but at the same time you are talking about $750+ to add them once you factor in almost $600 for another pair of QS8s, and just $150 for an amp. There has to be a better way. LOL
