Wiring in series means that you start by connecting the positive output terminal of your amp to the positive wire on speaker A. Then you connect the negative wire of speaker A to the positive wire of speaker B. Finally, the circuit is complete when you connect the negative wire of speaker B to the negative output terminal of your amp. This can be done for any number of speakers, so long as you follow the pattern (amp+ +speaker- +speaker- +speaker- +speaker- ……… +speaker- -amp). [1] X Research source Wiring in parallel means that you will connect the positive output terminal of your amp to the positive wire of all speakers in your system. Then you would connect the negative output terminal of your amp to the negative wire of all speakers. [2] X Research source
Wiring in series increases the impedance of your system. This decreases the amount of power received by each speaker. Each speaker added will also raise the impedance of the system. [3] X Research source Wiring in parallel decreases the impedance of your system. This means more power will go to each speaker because adding speakers to the circuit will lower the impedance of the system.

The formula for finding total impedance for speakers wired in series is Z1 + Z2 + Z3 …. = Ztotal. Where Z is the impedance of a given speaker. For example, if you have three speakers with impedance values of 4 Ohms, 6 Ohms, and 8 Ohms your total impedance wired in series would be 18 Ohms (4+6+8=18). The formula for finding total impedance of speakers wired in parallel is a little trickier. It is (Z1 x Z2 x Z3…) / (Z1 + Z2 + Z3…) =Ztotal. So say you have two speakers with impedances of 6 Ohms and 8 Ohms. This time it would look like this: 1) Multiply the values. 6 x 8 = 48 Ohms 2) Add the values. 6 + 8 = 14 Ohms 3) Divide the top by the bottom to find your total impedance. 48/14 = 3. 43 Ohms (rounded) You can also use an impedance calculator such as this one http://www. speakerimpedance. co. uk/.
You can wire some speakers in series and some in parallel within the same system to reach the desired impedance/power values. [10] X Research source
