Or, one  can tape a big plastic garbage bag to the top of the amplifier and   
time how long it takes to fill the bag with air. If a 20 cubic foot  bag  
fills  
in 20 seconds then you have a flow of 60 cubic feet  per minute.  Should 
agree 
with the temperature calculations.

I  think credit goes to G3SEK for this technique.




Wouldn't the flow  actually be GREATER than 60 CFM because as the bag 
inflated it would be ramping  up the back pressure the fans would be working 
into?
