I think car audio all depends on the vehicle, tbh. I have the upgraded sound package in my 2011 Mini Cooper, and the speakers are H/K. They sound legit, better than any standard sound system, and most likely, better than any post-manufacturing upgrades I could install myself. Then again, I doubt my Mini would require nearly as much audio capability as a bigger vehicle, an SUV for example. The upgraded H/K system sounds great in a mini, but might not sound as good in a bigger vehicle.
