Yes, it works as you described, but this is a very weak amp. It could be enough for pucks or half powered auras though. Great for an introduction to simvibe and tactile feedback. My only concern would be if there is any high pass filter inside (which I don't think there would be).Give it a try.
Simvibe differrentiates each channel position wise. One channel for shifter, one for seat, one for pedals (the three are extension mode) and 4 channels for the four wheels (this is chassis mode). In each channel you can change the effects and intensity of them. e. g. for seat channel you add rpm, road texture, bumps etc. for pedals road texture rpm, gear shift, brakes, wind noise. What you feel and how you feel it.
