If your amplifier has an A and B speaker selector, you can use this for a simple way of connecting two sets of speakers in parallel. To calculate the total load impedance of speakers in seriessimply add the impedances together. If both speakers are less than 8 ohms, or the amplifier requires a total load impedance greater than 4 ohms, then it is best to connect the speakers in series.
Speakers in Parallel
This is because two 4 ohm speakers in series makes the total load impedance 8 ohms. Two 6 ohm speakers in series makes the total load impedance 12 ohms. Most amps work fine with a load impedance of ohms. Below is a table showing how to wire up two speakers in parallel and series for common scenarios.
You may have noticed that no matter which scenario is used, all the parallel diagrams are technically wired the same as each other - if you doubt me, trace the connections with your fingers on any two of the parallel connection methods. You can do the same for the series connections below as they are also the same as each other. Keep in mind that changing the total load impedance of an amplifier will increase or decrease the power output of the amplifier.
Connecting in parallel normally increases the output power, while a series connection normally decreases the power output of an amplifier. Each speaker may have a different sensitivity which may mean there will be a level difference between them.
For more on this see Understanding Speaker Sensitivity. Also if the speakers each have a different impedance, then there will be different power levels available to each speaker. My calculators for Speakers in Parallel and Speakers in Series also calculate the way speakers with different impedances share power.
There are only really two ways to connect 2 speakers to one amplifier - either in parallel or series. If each speaker has an impedance of 8 ohms or more, then you can generally connect them in parallel. If you still have a question on how to wire two speakers, please read the FAQs before submitting your question. You may also find an answer in the questions and answers below.
European and Australian readers can use the links on the side panel - Thanks for the support. Hi I have two 8 ohm speakers and two 6 ohm speakers what is the best way to wire them to a stereo amplifier. The amp ssys 4- 16 amps thank you. Hi David, The best way to connect them is in series as shown above. If you connect a 8 ohm speaker in parallel with a 6 ohm speaker, then the total load on the amp will be 3. If you connect them in series, the total impedance will be 14 ohms, which the amp will cope with nicely.
If you want them permanently connected, then you can wire them as per one of the diagrams above. Hi Sir I have read your articles about connecting multiple speakers to one hi-fi amp.
In my system I am trying to connect 6 Boss MR4. I want two of the speakers to be connected with impedance matching volume controls. The rest of the speakers will be directly connected to the amp.
My plan is to sum my incoming audio signal. Then connect 4 4ohm speakers in series to make 12ohm on the left side of the amp.
Hi Todd, You seem to have sorted it out. My main comment is on your math.
Apr 20, Before sharing the tips on how you can hook up powered and passive speakers together, let us briefly discuss the differences between the two. Passive Speakers A passive speaker is the type of speaker that consists of crossover components that split the audio signal and sends those signals directly to the loudspeakers. Mar 09, Connection TV and speakers using audio converter. I went to shop that sells audio technology and they sold me Cabletech ZLA digital to analog audio converter. It's small black box that comes with USB cable to power it. All other cables were separate buy. I bought Toslink cable and RCA cables. Here are nice illustrative images of these. This diagram helps show why speakers connected this way are call "in series" As you can see, the two speakers are in "series" with the each other. How to Connect 2 speakers in Parallel and Series. Below is a table showing how to wire up two speakers in .
Also be aware that the impedance volume controls will only reduce the volume from whatever the amp volume control is set to. So on a typical stereo amp which only has one volume control you will need to set the volume for the four speakers.
Hi Coola, There are two options for connecting two speakers, they can be connected in series or in parallel. Connecting them in series adds their impedance together, that is your two 3 ohm speakers wired in series would give you a 6 ohm load to the amplifier. The other way would be to wire them in parallel. In parallel the total impedance is half of the impedance of the speakers, so that your two 3 ohm speakers would give a total load impedance of 1.
Hello Geoff, Thanks for your mostexcellent articles. They have helped me narrow down my issue so that I feel I can properly articulate my questions for a hi-fi of 75 W rms per channel that support 6 ohm speakers where I want to add one 4 ohm speaker per channel : 1 can I use different guage speaker wire to help balance the power to the speakers; either to increase power to the 4 ohm or decrease to 6 ohms if wired in series - which seems to be the lessons I learned on your pages.
I have noticed that none of the diagrams online show this kind of configuration. Thanks for your comment. I would like to put 3 speakers on The left side of my room and 3 on the other. How should I mount these? Then do I wire them in parallel or series? I plan on putting a volume control on the patio as well to control from outside. Your email address will not be published. Adding Speakers in series increases the overall resistance of the circuit.
How to Connect 2 Speakers to 1 Amplifier
The formula for Parallel Wiring is: When n is the number of Elements Note: If more than 2 Speakers are connected in Parallel, so long as they are all the same impedance then the net impedance of the load is equal to the impedance of the one Speaker divided by the total number of Speakers.

Example: You have the same two speakers, but the amplifier has a 4 ohm output. Plug the negative terminal - of the amplifier to the negative terminal of speaker 1. It depends on the impedance of the speakers, or the electrical load the speaker puts on the amp.
Check the back of the speaker unit or box to look for the number of ohms listed. Then, check the back of the amp to find its impedance range. If the sum of both speaker's impedance is within the range of the amp's, then they can be connected.
Yes No. Not Helpful 0 Helpful 0. A 4-ohm speaker with an ideal amp has a maximum output power of watts.
Speakers in Series. Two or more speakers can be wired in series. That is, one wire is used to to go from each speaker to the next. This is not normally used for more than 2 speakers. For a practical discussion on wiring 2 speakers in series, see the article on Connecting 2 speakers to an amplifier. To calculate the total impedance of speakers. Jun 01, Wiring up Speakers correctly to provide the best possible sound, requires some knowledge of Loading, Phase, and Impedance, while understanding Ohms Law will help you to connect your speakers properly. Although we discuss here two ways to wiring Speakers - Series and Parallel, we should mention Series/ Parallel Combination, so we have. For speakers in series, you add the impedances of the speakers together. To determine the wattage, you add the wattage of the speakers together If you were using ohm speakers, you'd have a 16 ohm cabinet. If you were using watt speakers, you File Size: KB.
A ohm speaker has a maximum output power of 50 watts. However, the number of watts a speaker can put out is affected by the amp that powers it. Not Helpful 0 Helpful 2. Not necessarily.
How to hook up additional speakers in your car
Many speakers don't need more than a few watts to sound great, and most listeners won't notice if a speaker has more watts. Higher wattage usually means lower distortion, but you can still have speakers that produce a great quality sound that's also low wattage.
Hooking up speakers is prettyeasy after you've carefully positioned the speakers in your surround-sound home theater. To hook up speakers, you just connect the speaker wires to the appropriate outlets on the A/V receiver. Before you plug and play, though, there are a few points to remember. Keep your speakers in phase. Each speaker wire [ ].
