Matt, you are somewhat on the borderline here.
If it were me, I would be running that amp bridged and getting 500 x 1 channel @ 4 ohms out of it.
Looking at the chart, you could push 2 of the 10W0 subs right to the max recommended rms so you would be rocking them nicely with that amp. I think it is always good to have a little more amp than needed, you can always turn the gain down to save the subs if its too hard.
Also, be aware that JL is rating these with the rms values, and not the cheesier "max value that the speaker can handle for 2 minutes before it starts on fire" values. So you still have a little safety factor.
So if you really want to run 2, I would get two of the 10W0-8 (-8 means 8 ohm) and run them in parallel so the amp "sees" a 4 ohm load. You will need an enclosure that is 1 cu ft to 1.8 cu ft in volume for two of those subs.
If space is an issue, you might think of going with just one of the 10W3v2-D2 which is a 4 ohm sub (because of dual voice coils). Your box would only need to be half as large. You could go with 2 of these if you have the extra $$ but you would then want the 10W3v2-D4, this would be very safe for the subs, but they would just start to break a light sweat when that amp is giving it everything its got.
So all things considered, if I were really going to go with 2, I would save some $$ and get the W0.
Also, there is a a lot of room up high behind the kick panel. You might think of building your box with an angled back so that it is short down low, and then takes advantage of the space available up higher.
These are my best guestimates. So if you get different advice from someone who sounds more knowledgeable...take it.
