You use the very farthest + and -. Most amps are only stable at 4 ohms bridged.

To your subwoofer yes. Don’t connect them together.

You may want to turn down(counterclockwise) the bass boost and the level knobs. Like Pwh said, most 2 channel amps are 4ohms minimum on bridged mode. Your subs are wired at 2ohms. Although your amp is 800 watts rms, it will put out more at 2ohms, and possibly damage your subs and amp.

How much more do I lower it and do I lower all of them

Lower them all the way. When everything is connected and turned on, turn up your radio volume about 75%(if distortion on door speakers, turn down until gone). First raise the LEVEL knob until your subs sound in trouble, then back off a bit. Turn your radio volume to usual listening volume, then adjust boost to your liking. Keep x-over switch on LPF. Turn on Subsonic switch, then turn the Subsonic knob to about 10 o'clock position. Good luck.
