is the amp too powerful..and would it hurt or damage my speakers?

Its crucially important they be matched because as everyone knows the amplifier puts out its maximum power the whole time and will quickly burn out the speakers unless carefully matched. Unless that is you got one with a volume control that works. In that case no, its irrelevant.

No. If you are actually listening.

Never enough power!

 My speakers are max peak at 250.
 Amps are 650 RMS@8ohm, 1000W@4 ohm.

never an issue.
 The more power the better!

  

It would work fine.

So would 100 Watts.  Probably so would 50.

Go with your best sounding best deal.

Best,

It's no problem to run 150 watt speakers with a 225 watt amps.  The amp is only going to output as much power as your volume setting determines.  Most listening is actually going to be in the 5 to 15 watt area.

Getting a more powerful amp is generally desired.  It's not because you want all that power.  It because you want the large power supply with larger transformer and capacitance bank.  This provide a much smoother sound with better current delivery to support strong bass and midbass signals, even if it's at low to medium volume levels.
