I know I could probably search but im ordering tomorrow so I want some quick answers. I drive a Grand Cherokee and I'm tall and big so my seat sits back and is tilted back so depending on how I sit while driving I can tell where the change in which speaker is dominant, so I was owndering if I should only run a component set up front, run compoents both upfront and back, or if I should run a coax off of headunit power for the rear?
