concerning those under seat subwoofers...

[Doel]

I'm trying to understand what's going on with the speakers in the Harman Kardon system. I know each door has a tweeter, mid range speaker, and woofer. When you have bass in a song, you can feel the vibration in the door, you can see your mirrors vibrate. The one place I can't feel any vibration is under the seat where the subwoofers are, I'll stick my hand down there and touch the grate, nothing. I've had subs in my other cars, in my house, those sucks vibrate like crazy when they work. I know the stock ones are little, but so little that you can't feel a single thing? I've tried the dollar bill trick and they will move a bill, so I know they're working, but if they're doing so little that you can't even feel them vibrating, are they realistically doing anything at all?

There is a very long thread on this already. Please search.
