Listen to him. You are going to ruin your staging and imaging if you install components in the rear. Use the money to get a better component set and/or amp for the front. If you insist on replacing the rear speakers don't spend a lot and just run them off the head unit. FWIW I only run my rear speakers when I'm watching movies (used as surround), when listening to music they are turned off in the head unit.Don't install speakers in the rear
