flip out radio
 

does anyone know if a flip out radio fits in an 05 dodge ram? i am being told that it will hit the overhang. but i also have seen people that have them in it. is there something that needs to be done? also i have the infinity speaker system. do i need a special wiring harness to hook up? i am being told that i need a harness that is like 160 dollars or the factory stuff wont work???
