I am going to build a custom enclosure for 2 Shiva's and power them with a Kenwood KAC-X811D amp (https://www.kenwoodusa.com/product/product.jsp?productTypeId=11&sortBy=price&productid=2580). Shouldn't this be about a perfect match in power for 2 shiva's?

Also, i am making a glass enclosure for them but could probably only afford 2.1 cubic ft. for both subs and the recommended is 2.4-3.0 cubic ft for both subs, they are going to to be mounted inverted so the drivers wont take up any air space, so i was wondering if some polyfill would work and how much? 

Is there anything else i should be thinking about?

Peace

Create a "basket" on the inside of the enclosure to keep the expanding polyfil from touching the woofer during play.  You could use a wire mesh found at the hardware store.
