I've never done rear fill but from my understanding the frequency should be 300-ish-3khz-ish, delayed a bunch and attenuated until it's not noticeable. Seems like a waste of a channel to me honestly. But ppl like what they like 🤷🏽♂️.
There's no need to use 2 sets if RCAs unless you want to keep fader function from your head unit.
Since your running a mono signal for your rear I think there is a trick. I think you flip polarity on one speaker so they are both not playing the same signal. I think 🤔.
