>>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...

Good ideas there. I'm thinking a return air grill going through the closet wall, above the rack maybe a foot below the ceiling. That would let warm air back into the room and encourage circulating air.

I would still punch holes in the amp shelves no matter what else you do. Don't punch so many holes the shelves break and dump your precious precious amps on the floor, of course.
