	~~==Impedance==~~

	Driving the load between two signals of opposite electrical polarity (often incorrectly called antiphase, or 180° out of phase - one signal is ''inverted'', there is no phase change) makes each amplifier see only half the load's [~~[electrical impedance]]. In practical terms, an eight-ohm loudspeaker could be safely connected to a bridged amplifier that was capable of driving four ohms per channel.<ref>{{cite web \|url=~~http://~~www.rocketroberts.com/techart/amp.htm \|title=Audio Power Amplifier Fundamentals \|year=2007 \|work=Joe's Tech Notes \|last=Roberts \|first=Joe \|accessdate=September 28, 2011}}</ref>~~

	~~==Benefits and drawbacks==~~

	~~Since two amplifiers are being used in antiphase, using the same power supply, there is no need for the use of a DC blocking capacitor between the amplifier and the load~~. ~~This way, it will be more linear and less expensive, use less space, and there is no power loss through the capacitor.<ref>{{cite book \|url=http:~~//~~books.google.com~~/~~books?id=Qpmi4ia2nhcC&pg=PA367 \|page=367 \|title=Audio Power Amplifier Design Handbook \|last=Self \|first=Douglas \|publisher=Focal Press \|year=2009 \|isbn=0-240-52162-5 \|edition=5}}</ref>~~

	Bridging an amplifier increases the power that can be supplied to one loudspeaker, but it does not increase the amplifier's total available power. Because a bridge amplifier operates in mono mode, a second identical amplifier is required for stereo operation. For bridged amplifiers, [[damping factor]] is cut in half, so [[speaker cable]]s should have a large diameter conductor or be kept as short as possible for minimum resistance. Because the amplifier's bridged output is floating, it should never be grounded or it may damage the amplifier.<ref name=Bartlett/>

	~~This output configuration is useful in applications where battery size dictates a lower supply voltage, e.g., automotive or handheld applications.~~
