How do You Bridge An Amplifier?

First thing you want to do is consult the documentation that came with the amp to determine if it is bridgeable, some amps are not. If your amp is bridgeable all you have to do is wire the speaker wires to that you have the right channel positive connected to the right channel positive on the amp. The negative wire should be connected to the left channel negative on the amp. Follow the same procedure for all channels.
