Well, for the first part, they are 10 inch woofers, Infinity Perfect VQ's. The volume I used for each woofer was .75 cu ft, which was one of many recomended volumes in the manuals for them. In the long run, they will be run by (probably) 2 infinity amps at 460 watts a piece.
For the second, I'm not entirly sure, except that I have seen it here:

I have a feeling however, that a similar product can be found elsewhere, at a lower cost.
