oam Impedance matching question?

I gotcha im not so much worried about the speakers as I am the amp the amp was $600 when I bout it I can replace speakers for $60 bucks but my man questions is by putting 4 speakers on a 2 channel zone 2 will omes be to much for the receiver?

I recommend that you install one of the controls / pair of speakers to the main speaker outputs, and the other to the zone 2 speaker outputs. That way you are safe no matter how high the volume is set (intentional or by accident).

You can use zone 2 for all of them, but you need to be careful as to how high the volume is set - and accidents often happen when the speakers are all remote and people at the receiver can not heard them until they are being over-driven and damage begins to happen, at their the receiver, controls or speakers.

You should not run all four speakers on zone two ONLY. Two on zone one and two one zone two should be fine.
