Can a stereo head be installed under the seat/has anyone done this?

this is a subject that i have been also thinking about. my solution for myself is to build a nice center console with a built in stereo and speakers, that will be easily removable with maybe 2 small brackets holding it in place. i plan on making it all internally wired leaving only the power and ground wires with quick disconnects. i would like to swap the unit between cars as needed and easily store in the trunk during car shows.
