How to Correct Power Amp for Speaker
Correcting a power amplifier to work with a speaker means configuring that amp to deliver the appropriate power for the speaker. For example, if the speaker is rated at 500 watts and the amplifier is 1000 watts, the amplifier will need to be adjusted to work with the speaker. In addition, an amplifier may need to be bridged to power more speaker than a single channel can provide. Not every amplifier can work with every speaker, but it is possible to make corrections in some cases.

Bridge the amplifier. Bridging occurs when a single channel of an amplifier is not powerful enough for a speaker. The two channels combine to produce more power. For example, if the speaker is 500 watts and the amplifier is 2 (channel) x 250 watts, a single channel will not be powerful enough. If the amplifier is bridged, then the speaker will receive 500 watts.

Connect the speaker wire to a left channel positive terminal then connect that wire to the positive terminal on the speaker to bridge a two-channel amplifier. Connect the negative terminal on the speaker to the right channel negative terminal. Connect the left channel negative with the right channel positive. The amplifier will now have been bridged. Always read the instruction manual for the amplifier before bridging, as some amps may require different methods.

Adjust the power supply on the amplifier. Some amplifiers have adjustable power settings. This is usually a switch or button that regulates the power which flows to the speaker. Most power switches have only two settings, for example, 250 watts or 200 watts. Locate the power switch on the amplifier and press it.
