Kuan and Whiskey Dan have my head spinning now. I don't get electricity.

I looked at my amp. It is a Sony STR-DE197 stereo receiver. On the back it says it has 190 watts. It has 4 sets of speaker terminals - an "A" set of left and right, and a "B" set of left and right (total of 8 wire connectors on the back of the amp). 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?
