You will waste your money and time changing from the STK4332 to a 4412.

The STK4332 runs off 24 to 30 volts maximum voltage.
If you fit a 4412 straight in there the output power will be the same.
You have to increase the supply voltage to 45 - 50 volts to get any increase in power out. Not practical or sensible for the rest of the units functions...
