Mounting CNAMPX-16x60 by rack ears?

[Heath Roberts <htroberts@xxxxxxxxx>]

Does anyone have experience mounting these amps in a rack? They're
fairly heavy (90lbs), and ordinarily I would expect anything designed
to be rack-mounted that weighs this much to have rails for a four-post
rack.

I noticed in picking the amp up that the center of gravity is only a
couple of inches behind the front faceplate, and I wondered if maybe
it *is* safe to rack-mount it by the front ears only--they're pretty
substantial.

So, anyone have experience mounting one of these by the rack ears
only? Or how did you support the rear?

Thanks,
Heath
