Help with body shaker

[Rocky_53 1,579]

Following a recent sim rebuild, I decided to install a body shaker. I found a 100w transducer and have wired it up to a Yamaha amp that was originally driving a full 5.1 surround system with subwoofer. While it works reasonably well, connected to the orbital speaker outputs, this is hardly ideal, as it is not receiving the lower frequencies normally driven by the subwoofer outlet. Unfortunately, if I connect directly from the subwoofer outlet on the amp, I get nothing. I understand that there needs to be a separate amp driving the subwoofer? This is where I fall down.I'm unsure what It is I need. Can anyone offer any advice. thanks fellas.

Those body shaker transducers need to be powered from an amp just like any other sort of passive (i.e. non-powered) speaker element.  Seems that the sub output from your home theater amp outputs a line level output for its sub channel, which is probably meant to drive a powered sub.  If you are lucky maybe your amp can be configured to drive that sub out at speaker level (i.e. to drive a passive sub).  Otherwise you'll need to get a sub amp to drive that body shaker, or cannibalize the amp from the sub that goes with your amp.

Thanks for the advice, appreciated.
