Speaker Wiring Calc is an offline speaker impedance and amp-load calculator for car-audio hobbyists, installers, and small PA setups that use series or parallel speaker wiring.
Use it to:
- calculate the ohms for each series branch
- combine parallel branches into a final amp load
- compare the final load against your minimum safe load
- split amplifier watts across the total speaker count
- share a plain-text result sheet before you wire a setup
Why people pay for it:
- speaker wiring math is easy to second-guess on site
- the app makes final amp load obvious before you connect hardware
- watts per speaker, total drivers, and load margin stay visible in one sheet
- no account, ads, subscription, analytics SDK, brand database, or server dependency
Speaker Wiring Calc is a math aid only. It does not inspect hardware, certify compatibility, replace amplifier manuals, or provide electrical safety guidance.
