Contrary to the opinion of many, these body sound generator would only be felt, I must admit. They are more than that. Attached I have the easy part centered under the backseat of my old BMW. Direct clamped in series to the radio, adjust EQ and behold: Especially in the deep bass range you can feel the vibration clearly, the bass is much more aggressive, toxic noticeably. How come? Precisely because the entire vehicle floor is set in motion by the vibration of the pump. The whole thing is not only tangible but just too audible.
Of course, this pump can not replace a sub. Should they also not at all. You should just feel as works convey something big. In my opinion, this pump can do that well.
Some might wonder why the pump is also audible. Now: It transmits the vibrations directly to your plate and I think only the vibration which works similar to a membrane here. Ironically, not tinny roar but really a clear, tangible and just crunchy deep bass experience.
Who is looking for an inexpensive alternative should view the Bass Pump quite even.
Car Hifi true enthusiasts do I yet his heart: The pump is not a full replacement for a woofer. In effect, it acts like a placebo effect because as the bass woofers just also on the body and the entire vehicle can be felt. But what exactly you wish for that? Sensible, healthy bass. And that manages this device out of the question.
Clear recommendation.
