Speaker sensitivity is a measurement of how well a speaker converts the amplifier power to to acoustic energy. Basically, when you bridge an amp you use the + terminal from one channel and the - terminal from the other. I have two one thousand watt woofers and a sixteen hundred watt two channel amp. Also if the speakers each have a different impedance, then there will be different power levels available to each speaker. Make sure your amplifier can be bridged. When you bridge an amp you combine two channels into one, bridging a 4 channel amp combines the 4 channels into 2. Amplifier power is probably the most misunderstood and abused parameter of amplifiers and speakers. Two amplifiers, each rated 100 watts maximum for an impedance of 4 Ω (four Ohms); in bridge mode they will appear as a mono amp, rated 200 watts into 8 Ohms.This is the most commonly misunderstood mode of operation and it requires additional circuitry to implement if the pair of amplifiers does not have the facility built in. When all cables are run back to the amplifier location. Both the theory and practical points on how to connect 2 speakers are discussed. Now you need to calibrate the speakers using the AV amp’s built-in, mic-driven set-up. Thanks! 2) Both speakers connected to one side of the amp.
