I have a prius with the factory jbl system. will this work by tapping the rear door speakers?

The LCi requires a full-range signal to work properly so more than likely use the front door speakers as an input, remember you are piggybacking off the wires so the speakers you get the signal from will still be operational. Hope this helps!

Can I buy just the bass knob

It's been a while but the last time I was on you were able to purchase a base not by itself just put up on your search bass knob for whatever you're buying

are these just for stock radios or can one install this on a aftermarket stereo?

You can put it on any radio. There’s really not a reason to put one on an aftermarket radio. All your doing is putting in a rca hookup for the amp. Most if not all aftermarket HU’s come with rca hookups now. On a side note if you do need one, shop around. This is junk. And way to expensive. I’m about to just buy a amp with high level hookups and trash this LCi2 it’s junk

will this work on a 2016 audi with bose fiber optic system? Ive tried a different LOC and when its attached to the speaker wires the I lose signal.

Not that I'm aware. Best bet is to call Audi to verify
