What is the difference between parallel and series subwoofer wiring?
Parallel Wiring This is a wiring configuration that applies the same voltage to all the connected components. The current from the amplifier is then divided equally among all the drivers according to their respective impedances. When wired in this manner, the overall impedance of the system drops. As more speakers are added to the parallel configuration, the lower the impedance. Series Wiring This is achieved by creating a single electrical current path across all the components. When multiple speakers are wired in series, the total impedance of the system increases. Series wiring is realized by connecting the positive (+) speaker terminal of the amplifier to the (+) terminal of speaker A, the negative (-) speaker terminal of speaker A to the (+) speaker terminal of speaker B, the (-) speaker terminal of speaker B to the (-) negative terminal of the amplifier. Any number of speakers can be inserted into the series of speakers that are wired together.
