If you are going up to the 6.5", you will need to add the cost of the brackets ($50), and an amp ($150 up plus wiring harnesses and mounting hardware for the Rockford Fosgate PBR 300......more $$$$ for the Hog Tunes or Titan), but does make a huge difference. Stay away from the cheapie amps sold on ebay.
