They can easily be modified to mount onto a computer chair or having a few on a false floor.I have them turned off when i am listening to music but when movies are on it is time for the shakers to shake.I made a board and fittings so it fits directly behind the back part of my couch and i fitted some foam between the board and the couch back where your back is.Under heavy bass the whole board shakes and pushes the foam into your back area and because the board is mounted to the sides it shakes the armrests.
I am using my old yamaha prologic amp which is rated at 80 watts per channel.These speakers are 4 ohms so MUST be connected in series to get 8 ohms to run them on most home stereos.So you can run two off your left front channel,two off your right front channel and two off your center channel.Make sure all wiring in your couch is secure either with tape or glue.
I had one problem though when setting mine up.I used a rca plug to two rca plugs splitter adapter to go from my main amplifier to my subwoofer and the second to the amplifier to operate the shakers.My main amp chooses the settings,volumn etc for all speakers including the subwoofer and the setting was -4db..But my shakers want +8db.If i turned my main amplifier to +8db it would be far to basy and horrible.Luckly i was able to get around it because my main amplifier has two seperate subwoofer outputs and i could seperate the two.
If your amp only has one subwoofer output buying a seperate subwoofer amplifier will be a better option because they the levels can be seperated.
These are actually made to put under the seats of cars to shake the seats while you are driving..
