If all the mosfets fit you can use anything. It all depends on what load you put on it also depends how loud you put it. For a quick test you dont even need to put it on a heatsink. Just be carefull the metal side of the mosfets have the voltage rail on it. So dont put it on a conductive plate...
Thanks for your input Jim
But do you think it is wise to earth the modules negative side. The modules are basic +30 0 -30 in bridge mode. I have not tested the 2 diode mode yet.
You still need to earth the module. Not sure what will happen if the negative and earth is equal.
I am not that clued up with the math. But I need to know the difference between mosfet and hexfet amplifiers. It seems these days you can build a amplifier with less components than in the old days. So here is my questions. What makes a amp module beter. What are the key factors that you have...
