Additional combinations and values may be calculated with our Parallel and Series Calculators. If you do not find the information you're looking for, please post your request at the12volt's install bay - Mobile Electronics Forums. We will NOT respond to any requests by e-mail.

Below are the available wiring diagrams for the speaker configuration you selected. The resulting impedance (ohm load) is considered the "Nominal Impedance" seen by the amplifier.

Note: One or all of the wiring options shown in this application may not be compatible with your amplifier because of low impedance loads. Please check your amplifier owner's manual to determine the best wiring option and verify the overall impedance load is compatible with your amplifier before making any connections. When making any connections, observe proper polarity to prevent damage to your amplifier and/or speaker system. *The location of positive (+) and negative (-) speaker terminals have been reversed in one or more diagrams for easier readability.
