Just had a buddy install a new radio on my 4320. You must remove the roof. It is not hard (13 nuts) but you will need some help to lift the roof without messing up the seal. When replacing the roof just be sure you set the roof down w/o sliding to insure a good seal. A/C will not work right without a proper seal. Don't know if speakers come without a factory radio. I replaced mine with AM/FM/CD/Satellite. As I said it is not a hard job. You can do it...
Ditto...... Several of us folks have had to deal with roof seals leaking after having the roof off to install radio and speakers. Two people are absolutely needed to remove and install the roof. You must lift straight up to remove and straight down to install. Radio install is not difficult. Good luck.
