Well for what it's worth, I went to a Kenwood Excelon system, with a DSP, X802-5 amp, XP184C components in front and XR-1800 coaxials in the rear doors. I'm still looking for a sub, but I'm very happy with the sound quality and volume. I like to ride with the windows down and sunroof open using my phone on USB, volume was needed from factory non Bose system.
