Sounds solid. Nice 'burban, by the way.
Not sure what you had in mind for budget, but I hope that fit the bill. ONE minor change, though. IMO, to get peak power available to run a 12" sub, you need to run 2 ohm. That means a dual coil 4 ohm, or a single coil 2 ohm speaker. It is always a good idea to have max power available, and turn it down, than to not have enough power and push an amp to its limits.
Dual 4 ohm version: (wired parallel = 2 ohm)

Just to throw a curve ball out there, JL W3 series get good recommendations for small enclosures. However, they are single coil, so you would need the 2 ohm version:

I don't have an opinion either way, you'd probably get 50 different opinions on which one and it probably comes down to brand loyalty.
JL components are a solid choice. Rears are typically for rear seat listeners. If you just want them for hearing music behind you, you can save a couple $ by going coaxial such as JL c2-650x @ $130. Neither choice is wrong, but definitely go components in the front.
Good luck!
