What ampli to use with 4 speaker?

[yobagas]

Hi I just moved in a new house and I found 4 ceiling mount loudspeaker. I would like to know what ampli to use so they don't blow up. I also would like to know how to know which wire goes where because both of them are of the same color. The only difference is that one of them has a white part on it.
