This app calculates approximate voltage drop on cables and power sources in 12 V car audio environment. Calculation equations are based on real world testing from successful car audio competitors.
App also calculates final voltage on car audio amplifier and recommended fuse size.
App can also consider voltage drop on power sources (battery and alternator).
App can be very useful for everyone who wants to estimate battery and cable size, needed to support powerful car audio amplifier.
Units can be changed under settings (metric or imperial).
