help with system installation, amp, sub, comps

Hey guys, I'm pretty new to car audio, so I need some help. I just bought a cadence amadeus m4000 digital amp, a jl audio stealthbox with a 10w3v3-4 300 w sub, and phoenix gold 6.5" octane-r comps. I've heard many stories about people that take theirs to get it professionally done, and the professionals fuck up the system, or don't really know what they're doing, so I was hoping I could do it myself, with your help, of course.
First off, here are the websites with the stats of all the things I have.

What would be the best setting for the amp to be hooked up at? What are the differences between 4 x 100 rms, 4x200 rms, and 2x400 rms Bridged?
any help is greatly appreciated, and many thanks ahead!
