I believe that the Premium Audio is a 150Watts with an option of a subwoofer... I don't think that it is better, considering that the AU series had 250Watts, as did the E-series (except it had DSP too). I would imagine that the ICC will cause a headache for after market sound files who wish to put in a 'bigger system'.
I would presume that the BA system will tuned better and will suit the car better than any previous attempts, but for pure performance, I don't think that 150Watt will stack up. Consider the VY Calais - it's got 250Watt, but also has ten speakers!
If anyone has listened to the systems and run a comparo - how did the BA sound?
