I'm using a solid state 800w/4ohms amp head and a 8x10 2000w/4ohms speaker cabinet. Is this okay for the cab and head? My head also says it runs 450w at 8ohms on the master dial. Is this okay to run on my cab or should I keep the master at 800w at 4ohms (max) and keep the volume down. Thanks in advance.

Read the sticky thread about ohms at the top of the amps forum. It doesn't sound like you understand what they are and how they work.
I did it for years w/o any problem, a 18 Watt tube amp into a 400 Watt 8 Ohm cabinet.
You match the impedance, don't switch your amp to 8 Ohms into a 4 Ohm cabinet.
That 450 Watts at 8 Ohms just means that if you plug in a 8 Ohm load the amp will only output up to 450 Watts.
If you're using a 4 Ohm load, then the amp can output all 800 Watts.

Your 2000 watt cabinet is perfectly happy with a 10 watt amp. Your 200 watt cabinet is perfectly happy with a 3000 watt amp. It's really not rocket surgery.
There is no such thing as "underpowering" if that is your concern.
Might want to rethink that last statement
OP, the watt rating on your speaker cabinet indicates the amount of power your cab can take safely. "underpowering" it is the same as turning down the volume to it. As long as the Ohms rating isn't too low for your amp (assuming it's solid state) you will be fine.
The only caveat that I can think of is that you might not be able to power the 2000W cabinet into it’s best sounding region.
If I may be so bold as to address Paula’ post. A 200W cabinet connected to a 3KW amp will be happy until it isn’t. Get the volume level high enough and the 200W cabinet will indeed fail!

Happily trending in my own peculiar direction.
You would be safer to think of it as a 500w cab, at least until you properly get your head around watts and ohms and RMS vs peak etc adfinitum.
Absolutely not a 2000 watt cab
Well that changes things. You may very well be OVER powering that cab which brings another set of problems, as it's nowhere near a 2000w capable cab.
Not even 2000 Behringer watts LOL.
Liars! It IS a 2000 watt cab...for at least 28 milliseconds!
Every time you turn your amp off you are underpowering your cab.
Just meditate on that until you achieve understanding.

It's a PERFECT match with a 2000w. Berhinger amplifier.

Notice in cab specs, the sensitivity specification is usually measured using one watt.
