As far as underrating goes...

If an amplifier says that it does 125 x 4 at 12v, then what number should i use at 14.4v for the gain setting tutorial?

If an amplifier says that it does 1100 x 4 at 12v, then what number should i use at 14.4v for the gain setting tutorial?

Is there a general rule for determining how much power an amplifier puts out at 14.4v if it is rated at 12v?

Depends....regulated or unregulated power supply?? //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif

Use this equation to determine the watts at the higher voltage IF its an unregulated power supply:

P = VI
