Gauge Power Calculator
Calculates the lost power due to cable composition & dimensions.
Helps you compare different cables and determine the least lossy configuration for your amplifier setup.

Type: Indicates the type of Amplifier, different types have different degrees of efficiency, and therefore consume more power for a given rated input.
Rated: The RMS rating on the box.
Consumed: The actual usage of electricity to generate the RMS output.
Volts: The voltage that the rating was tested against, typically 14.4V
Amps: The amount of current required (Ohms Law)
Output: The actual output when taking into account the Cable Loss
Colored Table: (W is the amount of Lost power for each combination of Cable type and Gauge, Total Loss should equal difference between Rated W and Output W)
- Green: Almost no loss, amazing.
- Yellow: Acceptable loss.
- Red: Unacceptable loss, if everything is Red & Black, consider a shorter run!
- Black: Dangerzone! Your amplifier could be damaged running this!
- Fuchsia: The voltage has dropped below zero at this point, so I'm assuming your amp has exploded
Note: 00 in this instance does not refer to 2/0 wire, but actually two separate runs of 0 wire, which would have the dimensions of 4/0.
