whis is best out of these subs, this is w

I have looked and I can afford

Rockford Fosgate Punch stage 3 10" (P3104D)

Rockford Fosgate HX2 10" (RFD2210)

Infinity Kappa Perfect 10" (10.1D)

Alpine Type SWR 10"

Kenwood Excelon 10" (1025DB)

I have a Kenwood Excelon 811D 1000Watts @ 1Ohm, These are all DVC subs. If you have any other sugestion I that would be great. but I think this is all I can afford I'm getting 2 of them.

Kappa Perfect. 

I would also consider one Adire Brahma 10" or 12" instead.

Definately the kappa perfect.  They put off huge sound with some great sound quality.  I've got just the kappa (one ten) and it put's my friend's pioneers (two 12") to shame.  That's my opinion but I'm able to vouch for their spl and sq.  It's probably the best for the price.  Two tens would be some sweet sound quality with a good amp it would put out some serious "loundess" (is that a word?).  The Alpines are my next choice.  Fosgate's hx2 is a possibility.  I know they are loud but not sure on sq.  The kenwood is my second to last only b/c i've never heard it.  My last choice (definately) is the new Rockford P3.  There are too many other speakers out there that put off better sound and last longer than the new rockfords.  Just my opinion.
