What Subs/Amp and box will fit perfect in a regular cab truck?

I have a 08 GMC Sierra regular cab, and what is the best sound system setup? I'm 5 6 so I'm not that tall so I will have room behind my seat, I'm wanting to put two 10's behind each seat, what are the top subs and amp that will work perfect and box designs or prefab box, pretty much what is the best setup for two 10's,
