Would you be able to build your own box? Take a look at the sundown SA8 sub. If you can build your own box itll save you money and probably sound better than that type r. They have some great output and sound nice. In a single cab you may get all you need out of a nice component set in the doors and the sub. no need for the 6x9s. Honestly in my crew cab i dont feel i even need my coaxials in the rear doors, especially with my 10" sub under the seats.
