Enter your Number of Speakers, Individual Speaker Impedance, Voice Coil Type, and Wiring Configuration into the Speaker Impedance Calculator to find your system's Total Impedance, along with Power Handling Capability and Amplifier Compatibility — so you know exactly what your amp can handle before anything starts smoking.

The optimal speaker load depends on your amplifier's specifications. Most amplifiers produce maximum power at their lowest stable impedance rating (usually 2Ω or 4Ω). Check your amplifier's manual for the recommended impedance range.
If the speaker impedance is lower than your amplifier's minimum rating, the amplifier can overheat, go into protection mode, or even be damaged. Always ensure your total speaker impedance meets or exceeds your amplifier's minimum stable load.
High impedance loads are generally safe but will result in reduced power output from your amplifier. Your system will work but won't achieve maximum performance potential.
In series wiring, connect the positive terminal of one speaker to the negative terminal of the next. In parallel wiring, connect all positive terminals together and all negative terminals together. Series increases total impedance, parallel decreases it.
Single voice coil (SVC) speakers have one set of terminals, while dual voice coil (DVC) speakers have two separate coils with two sets of terminals. DVC speakers offer more wiring flexibility and configuration options.
While technically possible, mixing speakers with different impedances is not recommended as it creates uneven power distribution and can affect sound quality. Use speakers with matching impedance ratings for best results.
Impedance matching ensures safe operation, maximum power transfer, and optimal performance. Mismatched impedance can lead to equipment damage, reduced power output, or poor sound quality.
Series-parallel wiring combines both methods - speakers are first grouped in series, then these groups are connected in parallel (or vice versa). This allows for impedance values between pure series and parallel configurations.
