What is series and parallel wiring?
Parallel wiring is a wiring scheme that connects two or more components by connecting all positive terminals together and all negative terminals together. The load impedance drops when speakers are wired in this fashion. The greater the number of speakers that are connected in parallel, the lower the total impedance. In general, amplifier output increases with lower load impedances. The number of speakers that can be connected in parallel is limited by the minimum load impedance of the receiver/amplifier that powers the system. Typically, 6 or 8 ohms is the minimum load impedance for receivers. Most power amplifiers are capable of operating at 4 ohms or 2 ohms. Series wiring has the opposite effect of parallel wiring on the total impedance. The greater the number of speakers that are connected in series, the higher the total impedance. With series wiring, components are connected in such a way that current flows through the first component before it can flow through the second componen
