2 10 kickers in mustang

I have a 2002 Mustang GT coupe. I am wanting to put 2 10" kickers in the truck. I am new to the scene as far as subwoofers go. I know kind of what i want Kicker - CompVR 10" Dual-Voice-Coil 2-Ohm Subwoofer or Kicker - Comp 10" Single-Voice-Coil 4-Ohm Subwoofer and then what is a good amp, doesn't have to be kicker. I am wanting good sound quality, the loudness of the bass means nothing without it sounding good. My mustang also has the Mach 460 stereo system in it and has the two amps in the back. Also, I know I probably wouldn't need a separate power supply but are they nice to have? I'm looking to get the differences between the two subs or if you have any other brands in mind feel free to shoot them out and why. I am looking for 2 10" no bigger, thanks again -Joe ps sorry for the long post
