I think experience varies a lot on these and satisfaction depends on your expectations.
I have 4 bass shakers (2 under each seat) with 200 watts driving shakers. I have 4 MB Quarts (5") replacing the HK's. I have 2 of the MB's mounted where the HK sub-woofer used to be, the other two in the footwells. Also replaced tweeters in doors with MB's neo-dynium tweeters. 300 watts total to MB's 5" speakers and 60 total to the tweeters.
I couldn't be happier with the sound level and overall sonic impression in the cabin. The bass shakers add a nice level of "thump" behind the the MB's which are tight and crisp. I can feel the bass shakers over road vibration with no problem. Sometimes it's a little strange because I think my vibrating pager is going off when the side seat bolster vibrates against my side! Anyway, I like them, but I wouldn't rave about them. I'd still like to add a small sub-woofer under it all.
I heard another car with a show class stereo that had 4 bass shakers along with all the other options and it sounded incredible.
I think the key is maybe to have 4 so you have more mass moving and power them sufficiently.
Robert's experience with the punch-through of the mounting hardware is definately a lesson to be learned from.

: I am trying to improve the sound effects of the Harman-Kardon system in my Z3. I would like some advice with where I should mount bass shakers (there is no space under the seats!). I welcome any ideas. Thanks!
