Bavarian Stage 0? stage 2?
 

I am looking at the Bavarian soundwerks stage 1 package for my BMW x5 non DSP. I was wondering is there a stage 2? or a stage 0? i see a stage 1 but i dont see anything else. How good are these speakers? have anyone gotten them? I just ordered a JL500w/1 amp with a Infinity Kappa Perfect 12 sub, was thinking of ordering the stage 1 speaker package also.
Any comments are welcomed thanks

P.S- When i drive my BMW sometimes the music turns down by itself and turns back up again, its really annoying. Like when i'm driving 40mph and all of a sudden you can notice the music get turned down, but after 15-20 seconds the comes back up. Is this normal?

Thanks

I don't have the BSW upgrade, but the sound change has to do with the amount of road noise, which the car compensates for (I believe it is speed and noise variable)

wow that is so annoying, is there a way to turn it off?

wow I'd never heard of that before, is it documented?

The stereo will compensate for the speed of the vehicle. Yes, it is adjustable. Hold down the button under the cd cover for a few seconds and the speed volume adjustment should appear.

what button is that? the select button?

I do not have the NAV system. The button under the cover on my business cd is labeled "tone". Press and hold and it should present the speed adjustment.

i tried it, it didn't work, it just makes my screen go crazy. Do all the x5 come standard with this feature? maybe mine does not have it? and the radio system is just weird?
