Matching amp to speakers.

Ok so I've decided to get some Focal acess 6.5" components, they are rated at 60W Nominal (RMS?) and 160W max, I want to get a Soundstream picasso amp but I don't know what one to get, should the RMS wattage of the amp be equal to or above the nominal (RMS?) wattage of the speakers?

Heres the focal site: http://www.focal-fr.com/accueil_en.htm

Heres the Soundstream site: http://www.soundstream.com/sub/products_amps_picasso.html

I want somthing I'll be able to get on ebay or whereever for cheep and a lot of the product numbers listed on the site I can't find for sale ANYWHERE, so yea somthing I'll be able to get. Ohh and if it comes down to me only being able to get a more powerfull amp than I need would that be ok (assuming I can afford it)? Is having a bunch of extra power left over a bad thing or a good thing?

It's always ok to have extra power. That's what gains are for :). It's better really, because you won't have to get a new amp later if/when you get different speakers. I'm planning to get an amp for my CDTs that are 75 watts rms per channel, they're rated about the same as yours. The more power the amp has to work with, the better you'll hear the lows in the woofer. Good luck finding a picasso, they're not the easiest thing to find. Oh wait... Here ya go!

thats a lil over powered, lol, but it can always be used for more powerful stuff later.

Should I get a 4Channel if the price is right? I seem to remember seeing one for like $20 more with similar power to each speaker.
