I’ve used the Nobsound G2 100 Watt Mono Amplifier to drive 2 bodyshakers using the pre-out subwoofer channel my receiver provides, so I’ve made a mount for it as well.
Note: The whole frame was made from dimensions found in the Amazon listing, so it’s close but not exactly fitting. I have added rubber mat/pads between the mount and the amp, which was planned to do anyway. The whole chair vibrates (duh!) so you want the amp not rattling around obviously. (...)
