What wattage speakers do I use with europower ep2500

Wow thats a serious system you have there.God help the neighbours!Anyway here is an example.you need a pretty serious speaker.At 8ohms,you would need something like a 8ohm 450watt speaker system.Anything smaller will stress your amp if you turn it up.The amp would kill smaller speakers or the amp internals(channels)at higher volume.It would be like hooking up a garden hose to a fire hydrant.Something would have to give.hope this helps and happy listening
