Hey i'm new to the forums and hopefully will be getting a new 3 series within the next few months. Before I get too involved I was wondering how easy it is to do a speaker upgrade if I decide to get iDrive for the car. I know on my A4 i had to change out my head unit because the stock one was low-output. I can't remember the terminology completely but it was something like that. Am i better off not getting the iDrive and buying an in-dash display or will I be able to upgrade the car speakers, subwoofers, add an ipod, etc. with the iDrive and still maintain good audio quality.

Thanks
