Good news! We upgrade fp20000q amplifier successfully. The fp20000q amplifier temperature can be reduced 15-20 degree Celsius when working.
What aspects did we upgrade FP20000Q?
|Increased the capacity of Siemens capacitor from 3300uf to 3600uf.|
Power supply board more stable
|Add more 8 small fans on the backside.|
Better cooling system

Must know before buying:
Full-range speaker [line array speaker, professional speaker]: the power of the power amplifier should be greater than 1.5 times or more;
Subwoofer speaker: The power of the amplifier should be more than 2 times or more, because the current of the low frequency speaker is larger than that of the full frequency speaker!
