Congratulations!!! You will not be disappointed at all with your decision. I've had my Viper for a little of a year now and I still go out to the garage at night just to take a look at it. It always brings a smile to my face. Welcome to the Viper Nation.
Not sure about the stereo in the newer Vipers but in mine I did replace the stock headunit and speakers. With the top off it was very difficult to hear and the sub between the seats was pretty much useless. Do some searches on the board and you will get some good ideas on some of the upgrades folks have done. If you think about changing your setup let me know - I have a Alpine receiver (CDA-7863) and Polk speakers I will be selling. I just upgraded my stereo again with a indash 5 inch monitor and dvd player. You will never run out of ideas for mods you want to make to the car.
