Avoiding the need to buy additional amps if you’re reusing old electronics.Using one 4-channel amplifier as a 2 channel amp to drive component speakers with more power and lower distortion at high volumes.Powering both front or front and rear speakers and a single subwoofer from a single two or four channel amp.

In the case of car audio installations, some of the most common uses are: What are bridged power amplifiers used for? This makes bridged amplifiers flexible for different speaker systems and especially for driving power-hungry bass subwoofers. The end result is effectively a mono amplifier with two times (or more) the power output of a single channel. When a pair of bridgeable amplifier outputs are wired to a single speaker in bridged mode, the two channels work in a push-pull fashion, sharing the speaker load impedance between them. While this feature is extremely common in car amplifiers, you can also find some home stereo amplifiers, PA amps, and other power amplifiers. Bridgeable amplifiers usually use the positive terminal of one channel and a negative terminal from the other channel for the speaker wiring connections.
