The guy's at BSW sent me my order of the stage 1 speakers and the sub system for my 2006 E53 non DSP X5.
I self installed the systems and let me tell you how impressed I am with it.....
Better yet get you sum of your own!
All the guy's at BSW were wonderful and helped with my questions.

I am rockin out!
The speakers are much better than the factory system and the sub top's my expectations!

I can't wait for my Dice and Specdock to come in....

Special thanks to Jason @ BSW for your time and help.

Now I am cool!
