Audio Systems: Amp placing, speaker box, screws

Question
Is there anything wrong with mounting my amp on my sub box?

Answer
some people say the vibrating from the box isnt good for the amp but I dont think there's anything wrong with it at all.  Actually if your box is built so badly that it vibrates that much, you've got bigger problems than your amp getting rattled right?  Just make sure the holes you make in the box with the screws dont break the seal (a speaker box needs to be air tight) so put them in and dont take them back out.  and if you take the amp off in the future, put screws right back in the holes to fill them up so there are no leaks.
