Wiring the same woofer or multiple woofers in these three different wiring configurations will result in different impedance loads. Series: Is the method of wiring of alternate positive with negative terminals (string method) (Illustration below) Parallel:Is the method of wiring where you wire match 2 speaker terminals with positive to positive terminal and negative to negative. Series/Parallel: This configuration is a combination of both series and parallel. We recommend series for the terminal and parallel for the leads to amp.
