#Parallel equation calculator how to#
(I’ll explain how to do this.)Įxample #1: Let’s say we have three 4 ohms speakers wired in parallel. You can call this the “inverse sum of the reciprocals”, which just means we add up all the inverse (1/x) values then take one final inverse function to get the result. For parallel speakers of the same or different values, you can use the universal parallel speaker formula below.If the speaker Ohm ratings are all the same, you can just divide by the number of speakers used.When it come to finding the total speaker impedance for parallel wiring, there are two ways to do this: How to calculate the total Ohms load for parallel speakers. (I’ll go into more detail about this in another section below) 2. Note that if the total speaker load is higher than the maximum power output Ohms rating for your amp or stereo, the total power you can get will be lower. The amplifier, radio, or stereo’s power will be divided among them. When speakers are connected in series, they share the same electrical current. We’d just add these together like so: 8Ω + 8 234 + 16Ω = 32Ω
#Parallel equation calculator series#
To find the total speaker resistance (impedance) for series speakers, simply add them all together.įor example, let’s say we have 3 speakers we’d like to use: two 8 ohm and one 16 ohm. How to find the total series speaker Ohms value Using a combination of #1 & #2 for more complicated speaker systems.ġ.As you can see from my diagram above, there are 3 main ways to do this: How to calculate series, parallel, or series-parallel speaker Ohms (DIAGRAM and examples)įiguring out the total Ohms speaker load for nearly any wiring configuration isn’t as hard as it may seem. Power to each speaker (“S x“): Power, in Watts, each speaker will receive.String (“Str x“) ohms: The series Ohms value for each string of speakers, 1 to 4 speakers each.NOTE! If the total speaker load would draw excess current (exceed the power rating you specified), this means an unsafe condition would happen and you’ll see “–” to indicate an error/invalid power amount.Total power draw from the amp or stereo: This shows the total amount of power the calculated speaker Ohms load will draw from the amp or stereo.Total speaker Ohms: This is the total speaker load the amp or radio will see based on the speaker Ohms you’ve entered.“Peak” or “maximum” ratings are misleading and will give the wrong results. If using the power option, use the RMS or continuous power rating in whole Watts for your amplifier or stereo. You can use whole numbers (2, 5, etc.) or decimal values (6.3Ω, etc.) for Ohms as needed. This will allow the calculator to determine power to each speaker in any configuration. Ohms rating: Input the amplifier or stereo’s power (RMS or continuous) power rating and the min. Speaker impedance (Ohms): Fill in the speaker Ohms value for as many or as few speakers as you’d like.Input your speaker Ohms and power values: Parallel-series: up to 4 speakers in parallel which are then in series with 1 or more speakers.(*Using 1 speaker in each string will effectively be the same as the Parallel speaker option)
