Well the catch with the w7 is tha the coil is 3ohms. So you need an amp that will do 500w @ 3ohms, your best bet would be to go witha regulated amp like the JL Slash or the Alpine PDX (same power at 2,3,4 ohms). You can also go with a non-regultated that will do around 350w at 4ohms and 700w at 2 ohms this way it should give around 525w at 3ohms.

10" W7 if you want it so much(great sub)
or
12" Fi Q in 1 cube sealed with 1 pound of polyfil on 1000 or so watts.
Total weight and space requirement between 10" JL and 12" Q is pretty much identical, only Fi will give you more output on same power of about 750 watts, but you can give Fi quite a bit more power if so desired, and even more with b/p option to push it even further during those basshead moments. Also easier to find a matching amp for Fi impedance. And since you have a very capable SQ rig, my recommendation would be getting a D2 and run it at 4 ohms on a 2-channel amp giving full power at this impedance. You'd be getting better speaker control on 4 ohms, and class A/B clean power. Full range D or G/H class can also be an option. I would not worry much about amp efficiency as this is for a daily driver. Or like someone else suggested getting something regulated like JL HD750. But if it's that important to you, grab a 1 ohm stable class D amp and run that puppy at 1 ohm, but I would not worry about it at around 1000 watts or so. Just make sure you get something with subsonic filter, so you can use it at around 25-30hz with 24db slope. Loud and clear, buddy! Thats all I got

p.s. Only problem, I would not like to run regulated on bass and non-regulated on front stage, as the reged amp may be reged for output as well at various voltages, and that would put your system balance out of whack while driving or idling, but that may be marginal, but still food for thought.
think about how you'd repair that FI sub when and if it breaks. Don't think there are any Canadian store fronts or retailers that sell it.
with all the subs that you mention you'd need 1000 rms of amp power or more.
W7 is ok, but probably the most expensive route to go since you will probably need a JL amplifier to power the sub properly (stupid 3 ohm coil config).
