I ordered the Fox Box from Foxacoustic for the dodge ram quad cab. I have two JL 12w3v3-2 in it with an Alpine 1000x1 and it's more than enough. In fact my amp is only half way up and it's crazy. I paid 200 for the box, and for a couple hundred more you can have the JL subs which are far better than those kickers in the box your link had or the power acoustic stuff.
Keep in mind that this is just my opinion, but spend a little extra and get the mid level JL 2-way or Infinity Kappa 6.5's those are nice and not too expensive and forget the polk audio stuff. Just make sure you get the adapters to save you time on the door speaker install. I'd think you would also want an amp to power all your door speakers to keep up with the sub's. 50 watts each speaker. Then hush mat or something like it. Again, this is just my opinion and I'm sure there is 100 different ways to look at it but I think that's a good balance between quality and volume.
