I've had many vehicles with many types of custom audio systems. I have to say I'm very pleased with my B&O 12 speaker system. The balance is incredible, clarity is very good, and bass response is perfect. I prefer the surround setting, but it does lose a little bass. I find, keeping surround on, if I bump the bass up almost all the way in the EQ, with mid setting at a little above center and treble around 75%, I have the perfect listening experience at pretty much any level. Add to that the noise cancelling and speed adjustment features, I feel it sounds more balanced than my last vehicle's custom 12 speaker with sub. The only thing that was better was the 2 12" subs in the rear doors of my Excursion.
