Everything I read says that if you are going to lower impedance but the drivers are more efficient, it negates any extra amp draw since it is using power more efficiently? But I don't have a confirmation of this.
However, I am debating sticking with 8 ohm Dayton Audio woofers, and leaving the other 6 at a lower 4 ohm. Will this make a difference keeping 40% of the drivers at stock impedance levels? The 8 ohm Dayton woofers are 88.7 db sensitivity, while the JL components and 4 ohm Dayton woofers are 92db efficient.
I'm driving myself crazy trying to figure this audiophile shit out.

Wish I could answer your question. In my experience (I used to be a pro mobile audio tech) changing impedance on speakers for OEM systems was not a good idea and almost always ended up with interference and distortion when listening to anything above ~25% volume. I am very surprised that the OEM DSP amp is turning out to be 4ohm stable across all 10 channels without producing negative results.
@prop, I can confirm that BSW's amp is not a very good unit. I want to replace mine as well but I went through so much trouble making it look/function so well in the electronics mounting bracket that I have a hard time replacing it.
I know I should, but the BSW just looks so good and solid where I have it on the rack that it keeps me from ordering a small form factor mono block to replace the crappy thing.
