Mixing Speaker Impedance?

I am considering purchasing either an onkyo pa-mc5501 or integra dta 70.1.

My question is that both of these power amps have a 4/6 impendance switch on the back of them. How will this effect my speaker setup if I am using speakers that have mixed ohms? My front L/R monitor audio RX8s are 4 ohms, my center gxc150 is 8 ohms, and my surrounds gx1 are 6 ohms.

Thanks,

in advance for any advice.

Resurrecting this very old thread...

I use the DTA 70.1 amp to run everything but mains & subs in a 7.2.4 setup. Currently the center, height and surrounds are all 6 or 8 ohms. I am getting some Tekton MOABs and a Double Impact Center. The DI Center is 4 ohm. Not sure what setting to use. The DI center is very efficient and likely would be fine at 1/2 or 1/4 power.
