Too little information given!
"Speaker system" is too generic - is it passive or active? What kind of connectors do the speakers / amplifiers have? What is the power being used? (by the size of the room, seems like a powerful one) How many speakers / amp channels are there? Is there a spider / distribution box or just an empty room?
If all this seems too complicated, try to find a technician with the proper knowledge in sound system design and implementation.
