Now you need an amp that will do either 100 x 4 @ 4ohms or you could just power the front components with a 100 x 2 @ 4ohms.
And the setup looks good so far.
If the speakers don't satisfy your loudness then consider a sub or subs to complete you setup, but worry about the front stage before the backstage (sub(s)) so get a 4 or 2 channel amp for the speakers.
This is my recommendation though.
