Series Parallel Speaker Impedance Series, Parallel and Series/Parallel Resistance. This page is for those who don't fully understand how to connect their speakers to their amplifiers to present a safe load to the amplifier. Most people want to connect their speakers in the lowest possible safe load to get the most power from their amplifiers. Parallel Series Speaker Wiring Diagrams - DiscountCarAudio Repeat with negative connections. If all speakers have the same impedance, the total impedance is the impedance of a single speaker divided by the total number of speakers. Two 4 ohm speakers in a parallel connection will have a impedance of 2 ohms. Series Hook-Up. Connect speakers in series to elevate impedance.
