All of my wired speakers are 4 wire speakers with colors white, green, pink and black
How do I connect to Sonos Amp or to CONNECT amp which only supports 2 wires.
Is there such a thing as a converter? I’ve searched for one but can’t find

Your speakers are likely stereo (dual voice coils) so one pair of wires will be the left coil and the other the right coil.
Yo sort out the wires you could use an AAA, AA or other 1.5 volt battery, or if hard to hear a 9 volt one.
Put one wire on the battery bottom and touch the other wires, one at a time to the top. The wire that makes the speaker click is the matching wire. Now look at the speaker cone and see if it moves out or in when the battery is connected. If it moves out then the wire on the battery + is the positive, in then it is the negative. Mark the two and test the other pair, then other speakers.
If two out of the three wires give you a click then you probably have a mono speaker and a cheap installer that used all four conductors to make up for having a too-small wire.
