There is no Droning in the car. It is not really loud in the car at all. You can tell its there when you tip into the throttle or accelerate. It sounds really good with the window open as well. It has the OEM sound these cars should have come with (more exotic and expensive sounding). Under normal driving you will not get tired of it, but it will get your attention under heavy acceleration. This is the system for the guy who wants a really deep sweet sound without being too loud.
