1. CEA-2006 Compliant — Standardized “Voluntary” Testing & Measurement Methods for
Mobile Audio Ampliers. This standard advocates a uniform method for determining an
amplier’s RMS power and signal-to-noise ratio. Using 14.4 volts, RMS watts are measured
into a 4-ohm impedance load at 1 percent Total Harmonic Distortion (THD) plus noise, at a
frequency range (for general purpose ampliers) of 20 Hz to 20,000 Hz.
