Speaker Impedance Calculator
This is an Excel spreadsheet which caters for various wiring combinations, in series and parallel, of 2, 3, and 4 speakers. It will calculate the power rating required for each speaker, and the impedance of the whole combination.
You must enter the power output of the amp in watts and the impedance of each speaker in ohms. The program will calculate the total impedance and the individual power within each speaker. Pictures of the different configurations are displayed on the spreadsheet, so you can use these as a reference for wiring up the speakers.
