Has anyone swapped their speakers out yet? I, like everyone else loves the sound of this car, but on a long ride down the highway I enjoy listening to my tune. These speakers really do suck so I'm going to swap them out with the Pioneer TS-D6802R. They arrive by Weds. and they will go in that night. If anyone has done this how did it sound, did you change the rear deck speakers too, thoughts on a custom sub for the back. I'm not looking for something that could be used to call Elephants 100 mile away but something to bring up the low end in my music. Any help is much appreciated.
