So, sick of reading, sort of. After reading like almost ALL of this. I think I want to go with a set-up I read from a couple years ago.
Faital pro 6.5's. speakers
SD evox 800.4 4ohm. amp. I plan on only running the 2 speakers. But left room for extra.......
Thoughts ?

Since those are a bi amped speaker you'll either need to use all four channels for the pair or get a separate tweeter amp. I think a 400.4 is best paired with the tweeter. They don't use hardly any power. Like 30 watts max I think. If you do use the 800.4, be very careful you don't overpower the tweeters.

Not familiar with bi-amping. Is there a wiring diagram for that ?

So I see I have 2 sets of wiring posts on this Faital coax. 1 for HF and 1 for LF. In order to put power to the LF, I will be using the other 2 channels on the same amp. What will be the best way to lower the power to the LF ?

One is for the woofer and one is for the tweeter. With these being 8ohm speakers you have 2 options... parallel bridge them or bridge them individually. Either way your going to get around 220 watts to each speaker. And on both scenarios, I'd power the tweeters with a separate amp.

As bates said, parallel and bridge the woofers to channels 1/2. You can run the tweeters in stereo on channels 3 and 4. However, I would highly recommend a dsp to drag down the power on those as you may not be able to turn it down far enough on amp. Shoot for 30 watts or so on the tweeters.

If you parallel the woofers, don’t you lose the stereo sound through them?
