In a space the size of a pickup cab you don't need rear speakers, just some decent fronts and a sub or two to get a great sound. I have a lot of friends heavily into their car audio who even compete here in the UK and they generally don't run rear speakers in a normal full sized car. Just a good set of component speakers up front and subs. I'm not into dance music or hip-hop etc so don't need ear bleeding bass, just want a better sound quality than I have currently hence the little 8" sub and eventually I will get a set of components up front either in a kick or custom door build.
