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

Too much power is like sex,you can never get enough.

Op it's not usually the amount of on hand power, it's the "quality" of power on hand...  If the amp is well behaved, and isn't driven to pass a bad signal, chances are your speakers, will never have a problem. 

Continual "clipping", fuse blowing, overheating, all the signs of abuse, will take their toll. Just like anything else... Keeping things tight, clean, routed, and off the ground, will pay dividends also...

You're more likely to damage your speakers with an underpowered amp.

Maybe.

No, really. Audiophile annals chock full of tales of speakers blown out by flea watt SETs.
