Sinbosen DS-20Q 4000 watt 4 channel professional bass power amplifier dual 18 inch subwoofer

Good news! We upgrade DS-20q amplifier successfully. The DS-20q amplifier temperature can be reduced 15-20 degree Celsius when working. 

What aspects did we upgrade DS-20Q?

Add more 8 small fans on the backside. Better cooling system

Increased the capacity of Siemens capacitor from 3300uf to 3600uf. Power supply board more stable

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!
