Without going into deep technical detail (which I can't. anyway), Bridging is when two channels are correctly joined in such a way that the combined output is at least the sum of those two channels.

This takes some engineering planning. You can't just "bridge" any stereo amp. Certain conditions and circuits must be present. But if an amp says it can be safely bridged, they provide directions andthe needed circuitry.

But, the down side to this great power is that distortion is somewhat greater and it "sees" the speaker load as one half of it's rating. i.e. it "sees" an 8 ohm speaker as a 4 ohm load. Usinga low impedance speaker may be cause for concern. So, some consideration must be made when choosing speakers for an amp that 's wired in this configuration.
