The amp is one of those fantastic ideas but was too expensive to complete properly. They added a female plug in for the fan, and expected everyone to add it. The amp used to get hot and snap off in the middle of a movie. Now it is working properly, and the glitches it used to have are gone. Using a fan to draw the heat through the vent holes, keeps the case cool, and even though it has a high power fan that works in high power conditions, built into the amp case, the low power states I usually use, never turned it on. The fan I added does a great job, and I don't even think about it during movies anymore...!!!
