I have to say, our experience at Bimmerfest this year was absolutely phenomenal. The weather was gorgeous, albeit a bit windy, and the people were a'plenty. We had hundreds of visitors at our booth, and from the feedback we received both during and after the show I can only surmise that you all enjoyed yourselves.
Our Stage 1
equipped E90 3 Series was VERY well received by the crowds as well. Not one person got out of the car without an ear-to-ear grin on their faces after having heard the dramatic improvement over the factory audio system that we "showcased" in an identical car for comparative purposes.
Yes, it is that easy and effective, and yes, you can do it yourself. In fact, I'm thinking about having a sort of BSW "listening experience" in several other cities around the country. Any ideas where I should start?
