First off, I am new to X5World and never really made an introduction. I am completely new to X5's and just picked up an 05 4.8is. I am coming from an E46 M3 and am really excited to learn all about this truck. You guys seem like a great group so I hope to talk with alot of you.

Now onto my newbie question! I keep seeing everyone talking about DSP in their trucks. I am assuming that is the premium sound system? And if I have the rear passenger side mounted OEM sub enclosure, I am guessing that means I have DSP? Thanks for the confirmation!!
