Query: These don't work we'll

I got the audio source amp 100 that puts 75w per channel @ 4ohms to go with it but but the 2 bass shakers I got will not rattle my teeth at all at max volume, at least in my set up they don't. One of the reviews stated that at around 15w the bass shakers rattled his teeth, that was not my case.I would not buy these again
