This was running music at max power into 2 ohms both channels driven for 1 hr 
continuous. All temperatures were well in control and stabilized. The thermals are very 
good considering the extreme levels used during this test. Most customers will never run 
this much power for this sustained time. Additionally the voice coils would have heated 
up and become like 4-ohm resistors.
