I have a pair on Infinity sl-40's and a pair of infinity rs-125's. Both sets are 6 ohm speakers with the sl-40's being between 20 - 150 watts and the rs-125's being at 10- 60 watts. Now, I'm trying to get more of a 360 sound for my audio room. If I was too get a receiver with a A+B channel the problem is I haven't found any that allow that low amount of ohms. Would I be better running them in 5.1 or do they make something that changes the ohm resistance before the receiver? Sorry for the long question learning alot of this as I go!
How should/could i run these in parallel a+b?

You could use something like a Niles speaker switcher, this will keep the impedance at 6ohms, I suggest one with output controls for each speaker pair.
There's another option, a receiver etc with pre out/main in, this will allow connecting two power amps using RCA Y adapters, one for each set of speakers so no impedance worries. If going this route I suggest getting power amps with gain controls to allow balancing their outputs to each other.

You'll need at least one more amp. In my case, my primary receiver
won't drive my main speakers at all, so I use it like a preamp. I have
two more amps and send front speaker signals ("pre out" not speaker
output) from the primary receiver to one and rear speaker signals to
the other.

See, I learned the hard way about finding out my Receiver doesn't accept 6 ohms by damaging it permanently. I was using an older Pioneer M-770 and CX-770 thanks for all the information though, I'll be sure to do some more research and digging as well! Got any good recommendations for good power amps? "I'm not exactly audiophile quality funds either" haha.
Also, would something like that Niles speaker switch allow both sets to be played simultaneously?

Yes that's what it's designed for.

Class D pro power amps are relatively inexpensive these days for big power.

What you are describing is called all channel stereo, it's not really 360 sound. For that you need an AVR and surround sound source material.

It will be difficult to find a receiver that will allow you to play both pairs of speakers simultaneously without going into protection or melting down.
Most receivers parallel the outputs and that will actually present a lower impedance load than the amplifier can support
An external amplifier or speaker switching device with impedance matching will be your best bet.
There are many very impressive class D/chip amps available for short money that would be well worth your consideration.
