ok, i just bought a NINE.2X from ED, but after looking at the pictures, im somewhat confused, how do these mount? does the whole amp come off the bottom plate just to mount it? which in turn you screw down to your amp rack? thanks for any help

 

Look around the box there should be a little bag with the feet and screws to mount the feet to the four holes on the bottom cover.
If you didn't get them, call who you purchased it from and ask for them.
