Parallel Wiring combines all positive leads together and all negative leads together. This reduces impedance and lowers the amp draw. Two 8 ohm speakers wired in parallel have a 4 ohm load MOL. It is important to know the parameters of the amplifier. Lowering the impedance beyond the recommended range can damage the amplifier.
Cathy grew up in NY, moved to Florida in 1975 and graduated from the University of South Florida, with a degree in broadcasting. She and her husband Glenn started The Speaker Exchange in 1977. (Glenn later moved into Audio/Video sales and installations).
