Are these modules using Lateral Or Vertical Mosfets?
Your web page suggests the use of a 40 0 40 AC transformer so 56 0 56 DC To output 450w RMS into 4 ohms the Output needs to swing approx 120v peak to peak. Could you quote the Rail voltages that you use on your '900W' Module?

40 - 0 - 40 is a minimum and is playing safe. The module requires +/- 60 volts to get the maximum output. However the capacitors are 63 volt so some care needs to be taken not to go over approx 60 volts. I have done a couple of orders for modules with 80 volt capacitors.
