Randy,
Another idea...
Old technology but it probably would help.
Is the door going to the closet solid?
If so, you could possibly cut a hole in the door and put a grate over the hole
like they used to do on older houses for the return air for the AC. Or find a louvered door to replace the one that is on the closet.
Would help to facilitate the air flow from the front through the rack out the back and out the door...
Another option may be to put a return air duct in the closet (if there is not one already)...it would accomplish the same thing...pull air from the theatre through the rack out the ceiling of the closet...
I believe they also make smaller exhaust fans that could be mounted in the ceiling of the closet away from the rack that you could control with the amps turn on function...it would vent it into the crawlspace or redirect it outside similar to the flatulence vent in your bathroom...
Just my .02.
