Subwoofer wiring does not have to be confusing. The way voice coils and multiple subwoofers are connected determines the final impedance—or load—presented to the amplifier. Choosing the correct series, parallel, or combined wiring arrangement helps the system operate safely and allows the amplifier to deliver its rated power.

Before selecting a wiring diagram, identify three things: the number of subwoofers, whether each subwoofer has a single voice coil (SVC) or dual voice coils (DVC), and the impedance of each voice coil. Enter that information into the appropriate wizard below to calculate the final load and view the corresponding wiring connections.

Always compare the calculated load with the amplifier manufacturer’s minimum stable impedance. Wiring below that rating can cause overheating, protection-mode shutdowns, distortion, or permanent amplifier damage. If the calculated impedance is not supported, choose a different wiring configuration or a properly matched amplifier.
