thanks heaps directedfx. really appreciate the feedback. i think i might just leave out the 6x9s. when it comes down to installation, it would be a professional due to the fact that im getting 5.8" screens into the headset and my rear arm rest modified to get the dvd to sit inside the arm rest and with the push of a button release up. similar to the 06 caprice's. so im really looking forward for those mods. also importing a module from the states to watch what ever the rear passengers are watching on my front sat nav screen.
