Can the 2200 handle a 5ohm load?

This is probably a simple one, but I asked anyhow. I see the spec for a 4 and 8 ohm load, so I am assuming 5 ohms will work fine and land right in the middle around 225watts output roughly?

Yes, it can handle 5 ohms just fine. They just rate it at 8 ohms and 4 ohms because those are standard points to spec.
