Do you mind posting this info? I'm trying to help my friend with his VXI amps to do rear fills properly. Not sure how to do the routing.The twk88 can do differential rear fill. A friend of mine told me how to set it up. I did and can verify it works.
Edit: FWIW, I'm not seeing any posts in this thread having been moderated so it must be something with the site today.
I played with this for the first time today. Here is what I came up with in my VXI amps:Did you ever figure this out on the VXi? I am curious as well
Hm. When I did the routing like yours under mixer path EQ4 with L input pos polarity / -6db and right input neg polarity / -6db I got no sound. I had to make a difference between the inputs (ie set the right input to -12dB).This is what I could remember. Test it out yourself and adjust level, crossover points and delay to your liking. Every car is diff.

Oh my goodness. I am glad you posted this photo cause now I realized why I had no sound: I was listening to mono pink noise at the time so both channels had identical information ;-) I will change the settings!Hm.

I also have my polarities the opposite of you under the idea of trying to make the L rear be L-R. Rear left I have as +L input and -R input.
It's not supposed to be noticeable, if done right.Hey all, so I set up the +L -R in my truck and it sounds pretty cool but it is not very noticeable, even with level cranked up. Is it safe to assume it is because my rears are low in the rear doors (2108 GMC Sierra quad cab)? My front stage is pretty f-in loud so that also could be it
How do you even go about EQ-ing a setup like this? Just curious... or does it even matter? Thanks!
Glad to hear all opinions! I am programming different rear fill options as presets and trying them all to see which I like best. Is there a configuration that you prefer that can be accomplished with a normal DSP? (I have a JL VXi) ThanksAnd it’s just my opinion that L-R methods don’t sound good
It reminds me of the hirem effect in a matrix surround from the 60s
It sounds dumb and boring in my humbleness
Seems to me we need to see a rear processor that has some reverb , decay , detune , twotap echo , all user defined .
TLDR I’m not a proponent of L-R rear fail

I've been trying "fronts only" since I installed a new amp and DSP and after over a month of playing with MANY different target curves and EQ, I've finally given up on "fronts only". I just do NOT like the way it sounds. To me, it sounds "thin" and just "bland" when compared to having the rear speakers playing as well. I have the rears at a lower level and band-passed. Still experimenting with different combinations, but right now, I have the rears band-passed at 75hz/7000hz, and EQ'd in a way that the frequency response goes "down hill" as the frequency increases - and I like the "fullness" it gives the sound. You don't actually hear the back speakers - meaning you don't even realize they are on - until you turn them off. With this type of setup, the vocals still come from the windshield, but you just get a much "fuller" sound. I just can't get used to "fronts only".
In my case, "fronts only" are 6x9's in the bottom of the doors and 3.5" coaxials in the dash, facing directly up into the windshield.
In the end, it all boils down to what *you* like and prefer. Obviously, my setup isn't "correct" in terms of a "SQ" install, but it makes me happy this way, which is what is important.
