I looked at my amp. It is a Sony STR-DE197 stereo receiver. On the back it says it has 190 watts.

Below the speaker connections it says "Impedence - Use 8-16 [ohms]", except it used the symbol for "ohm" instead of the word.
I have never heard of bridging an amp, so I did some googling on it. How do I know whether this amp is bridgeable?

OK, Your Sony is not bridgable. Some pro PA amps combine the A&B channels (left and right) to make one big power amp.
Since the amp will only handle a minimum impedance of 8 ohms you will have to wire two speakers in series and hook them to the left channel "A" . Then the two remaining and connect them to the right channel "A".
The Sony you have is rated at 100 watts per channel into 8 ohms. I doubt that will be anywhere near enough power for this application.
How big is the arena? How loud is the ambient noise?
