Parallel Series Speaker Wiring Diagrams & Explanations

Which type or wiring parallel or series will give you the most power? Find out all the information you need on parallel and series speaker wiring. Includes easy to read and understand speaker / subwoofer wiring diagrams.

Parallel Hook-Up

Connect speakers in parallel to reduce impedance. Connect all speaker positives to positive terminal on amplfier. 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. For a series connection, connect the positive terminal of speaker "A" to positive terminal of the amplifier. Next connect the negative terminal of speaker "A" to the positive terminal of speaker "B". Now connect the negative terminal of speaker "B" to the negative terminal of the amplifier. The load in a series connection is all of the individual impedances added together. Example : Two 4 ohm speakers wired in a series connection will result in a 8 ohm load.
