Rated vs actual: car amp power
6 amps where the video states a rating. Sorted from the biggest shortfall to the biggest over-performer. Note: the rated figure's load isn't always stated, so compare with care.
Summary of these 6 amps: peak confirmed measurement ranged from 38% to 143% of the stated rating; 2 of 6 measured at or above it.
How it's computed: peak confirmed measured watts (at any tested load) ÷ the RMS rating quoted in the same video text. Only 6 of our 44 amps have a rating stated in the source, so this is a small sample, not an industry verdict. The 4 / 2 / 1 Ω results for every amp are in the power-by-impedance study.
