2/4 way bridged mode can't figure out

[95GST]

My amp is a power precision A404.. I want to hook two speakers up in 2 way mode. it has this button "2/4 way" and I'm not sure which one is two way. I want to use the 2x200 mode which has better power, but also make sure I'm not running the 4x50 mode by mistake.

How does the speaker wires go in two way mode?

Does the connection block have any markings on it? When you bridge most amps one of the channels is reversed, so, one speaker would use the + from say channel 1 and the + from channel 2. The bridge button will invert the second channel 180 degrees so the + becomes a -.
Some of the amps I've seen have the bridged polarity marked inside of circles.

there's a block for front and a block for rear

I think it's - + + -

I just hooked to the 2 speakers to each of these blocks.
I noticed only one of the + will have sound. So maybe I am already in the 2 speaker mode. Not sure about polarity. It sounds OK to me?

if someone have a manual for their power precision amp of similar models.. Please let me know.

You will probably have to use the two outside connections ie - and -. The bridge switch will invert one of them. If you hooked up speakers to both of the connections it won't work. In two speaker mode you will use the front pair for one speaker and the rear pair for the other speaker.
