Got my replacement 500 amp yesterday and got it installed. The replacement amp came in a wood crate sealed with 4 inch wood screws.

Did some initial level matching and then popped in war of the worlds. Can't say I care for the movie much, but man did it show off the axioms . My girlfriend kept saying "It's shaking my !@# right through the couch!".

Also I listened very closely for any vibration or rattle in the 500 and couldn't find any.
