Will this fit under the front power seats of a 2008 F250?

Not sure about this particular truck, but it does fit under the front seat of my 07 Tundra. Sounds great too !

Can two subwoofers (one under driver seat and one under passenger seat be used with a factory head unit? if so, will it require any additional items?

Honestly one is plenty but if you want to double up on it your gonna need to wire a lot of things

Can you hook 2 together. Is ther a special harness you need. Thank you

You can split the input signal in two. You would DIY a harness.

The om says, the auto power-on feature is available only when using high level inputs. how does the sub come on using low level rca inputs?

Hello no, with the RCA out puts is no power on automatic just in high input
