how to bridge 1 X amp 2 channel?

Have you read your amplifier owner's manual?  What is the make/model of the amp?

A mono amplifier connection has only one "phase."  And, if you want to get technical, bridging a stereo amplifier does require one channel to be out of phase with the other.  Modern bridgeable amplifiers have an inverter module built-in.

Trini:  The proper speaker terminals to use for bridging a multi-channel amplifier can vary depending on the amplifier manufacturer, and not all amps are bridgeable.  Once a stereo amp has been bridged, it functions as a mono amp and there is only one phase.  Connecting multiple speakers to the single output is where it might be possible to have one speaker out of phase with the other.

reverse polarity = 180 degrees change in phase

so...saying "out of phase" is correct.  If it's not in phase, it has to be out of phase.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.
