How can I augment the cooling of my amplifier racks using external fans?

Crown amplifiers draw air in the front and exit out the sides (CE Series and Contractor Series (CH/CL Series) amplifiers exit air out the back). For this reason do not install auxiliary fans POINTING IN toward the amplifiers. The following are two suggestions:
  1. Place the fan in the back of the rack pointing out or away from the amplifier(s)
  2. Seal the back of the rack with the road case cover. Mount the fans to the TOP of the road case back cover POINTING OUT.
