![]() A more detailed discussion on speaker impedance and power output can be read in the article Speaker Impedance Changes Amplifier Power. The maximum power output of an amplifier is dependent on the amplifier design and total load impedance of the speakers connected to it. The speaker will also work when driven at lower power. The power rating of a speaker is normally indicating the maximum power you can safely drive the speaker with. If the amplifier can only deliver a maximum of 50 watts of power, then the amplifier can still only deliver a maximum of 50 watts of power irrespective of the power rating (capacity) of the speakers. It is true that 2 speakers rated at 50 watts gives you a speaker system with the capacity to handle 100 watts of amplifier power. Many people think that if they have a speaker rated at 50 watts, then adding another 50 watt speaker will give them 100 watts of power. The rated power of speakers is a concept often misunderstood. So if you want to connect 4 speakers in total, you are only going to connect 2 speakers to each amplifier. That is, either the left or right channel amplifier of your hifi. ![]() This article looks at how multiple speakers share power from the amplifier, whether they are wired in series, parallel or series and parallel.Īs in most articles, we are going to talk about speakers connected to one amplifier. However, in most cases, adding speakers will reduce the power in any one speaker. Often people are wanting to add speakers to their amplifier to increase power.
