How to Bridge An Amplifier?

To bridge an amplifier, first read all the documentation that came with the amp to make sure it is bridgeable. Next know how many channels you need to bridge. If you have a 4 channel amp, you will be bridging it to 2 channels, if you have a 2 channel, you will be bridging it to a 1 channel. Now identify your terminals, for each channel you will have a positive and negative terminal, label these, A channel 1+, B channel 1- etc. Now connect your speakers. On a four channel amp you will connect the red wire to the A terminal, the black wire to the D terminal, and then connect terminal B and C together with a short wire to create the bridge.
