Adding an AMP ???

I was hoping that someone could lead me into the right direction on what amp to get.

I just bought a set of
Blaupunkt Component speakers for the front they are
recommended power range 2-80 watts RMS per speaker
Peak power handling 240 watts

And the rear

Polk Dx9-which are
Recommended power range 2-50 watts RMS
Peak power handling 160 watts

To be perfectly honest with you guys I have no clue on where to start. I am not sure about 4 ohm or 2 ohm. I know that I want to power these four speakers off of one amp using my factory 6 disc changer and I am not sure if a if can get a two channel amp and run the four speakers at 2 ohm or just get a four channel amp and run them at 4 ohms.

If anyone could please tell me their suggestions and what they have done would be great.

Thank you all
