What does it mean to bridge speakers?
Primarily a live sound term, “bridging” is a means to configure a 2-channel amplifier to drive a single loudspeaker with more power than the two original channels. Typically, amplifiers operating in bridged mode can only do so with speakers that have twice the impedance of the minimum rating load on the amp.
