what is bridging?

[npham]

taking a pair of channels and making it 1 channel....

ie, 2 channel amp(left and right) can be bridge to make 1 mono channel

There's millions of sites that explain it. Basically, you drive one load using two of four terminals, commonly using the positive terminal of the left speaker and the negative terminal of the right to form a single high output. Mostly used to drive a sub with a 2 chanel amp, utilizing both channels instead of just one, and thus increasing total output capacity.

if you want to get all technical, bridging uses one channel to do one half of the waveform and the other channel to do the other half. so pretend 0dB is silent and you have a sine wave that is 20dB, you will get 10dB on one side of the line at 0dB and 10dB on the other side. each channel will play only one side, and it will play that side to its full capacity meaning you will get a lot more power out of your amp at a particular load.

as well, all amps bridge differently. some have a switch, most use the one positive one negative way. if you have certain kinds of mono amps, you can use two mono amps to bridge together to act as one mono amp and get huge power... briding two Rockford 1500bds, for instance, will get you over 3,000 watts at 4 ohms.
