SC600-T Maximum output power of Class-D amplifier


In the manual of SC600 it has written that "The maximum output power is 1.5W when load is 8Ω.
What would be the output power for the load of 4Ω?
In my application I want power output of 3W and load is 4Ω.
Can I interface speaker through another class D amplifier at pin 54 and 55 of module to get 3W power output?

Thanks & regards

you can connect a 4 Ω , but the output will not achieve 3W.

Maybe you can only get 2W for 4 Ω
