What factors are involved in bridging my amplifier?

Bridging an amplifier allows you to tie two channels of you amplifier together into one output, essentially turning a two-channel amp into a one channel amp, or a four-channel amp into a two-channel. The benefit of this is that it gives you more power output than just a single stereo channel being used to run a single speaker. It is usually used in the case of running subwoofer(s), since a bridged amplifier just has a mono output.

Not all amplifiers are capable of being bridged, and those that are will have specific minimum impedance and connection requirements.

Unfortunately, the wiring configuration required for bridging is not the same for all amplifiers, preventing us from providing exact information for your amp.

  • First, refer to the operation instructions for the amp to make sure that it is capable of being bridged.
  • If bridgeable, make note of which speaker terminals are specified as the bridged output connections. These terminals will either be identified on the speaker output terminal of the amp, or in the operating manual.
  • Finally, find out what impedance requirements the amplifier has for bridged loads, and be sure to stay within that range. Most two-channel amps will only accept a four ohm bridged load.
