u should be considering doing it chipamp way, using LM3886 in Bridge/parallel mode like BPA200 or 400, class D section u should be looking for LM4651/52, or LM4780 in brige/parallel application.

Have a look for ICEPower 500-1000ASP modules, these are readymade plug and play and just need a box, power cable, input and output terminals.

3886 is something around 100W.
buy some commercial amlifiers/modules or build a extremely big linear amp on a extremely big heat sink use extremely big transistors (or IGBT).
