Bridging an amplifier is a method of taking a two-channel amplifier and using the output to power a single speaker. It's especially useful when you're using the amplifier to power a subwoofer. Bridging an amplifier doesn't require any special skills or tools, just an eye for details, simple tools and some speaker wire.

Strip the insulation of a piece of speaker wire so that each lead of the speaker wire has 1/2 inch of bare wire visible.

Loosen the set screws of the "Bridged" terminals with your screwdriver, and slide the bare ends of the speaker wire leads underneath the screws. Then tighten down the set screws so that each lead of speaker wire is securely fastened. Connect the positive lead of the speaker wire to the positive terminal, and the negative to the negative.
