Too much bass? Absolutely.
Every new car I've purchased in the past 15 years or so with "premium" sound systems (Land Rover, Lincoln, BMW, Volvo, Nissan, Toyota, VW) has had horrible, boomy bass. The H/K stereo in our current X5 seems to have less of that problem, thankfully.
Oh, you meant home stereo?
Nope, no bass issues with any of our three systems thanks to careful speaker placement and bass-friendly rooms.
