Why are some car cd players CEA COMPLIANT?

Question

i WANT TO BUY A NEW RECEIVER BUT IT SAYS IT IS CEA COMPLIANT, AND ONLY 14WATTS RMS(50 MAX), AND i HAVE LAST YEARS MODEL THAT IS NOT CEA COMPLIANT AND IT SAYS 22 WATTS RMS, AND 50 MAX. ARE THEY STILL BOTH THE SAME STRENGTH OVERALL?

Answer 1

On May 28, 2003, the Consumer Electronics Association published standard CEA-2006, "Testing & Measurement Methods for Mobile Audio Amplifiers." This "voluntary" standard advocates a uniform method for determining an amplifier'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 amplifiers) of 20 Hz to 20,000 Hz. Signal-to-Noise ratio is measured in weighted absolute decibels (dBA) at a reference of 1 watt into 4 ohms. This applies to both external amplifiers and the amplifiers within in-dash receivers.

CEA-2006 allows consumers to be able to compare car amplifiers and receivers on an equal basis. Manufacturers who choose to abide by the new standard are able to stamp their products with the CEA-2006 logo that reads: "Amplifier Power Standard CEA-2006 Compliant."

Answer 2

it means that the power they say they have is pretty accurate
