How many watts is a stock radio?
Most dealers indicate the power rating of their standard factory car stereos to be 200w.
What is a good wattage for a stereo system?
If you like loud uncompressed music and your speakers are 90dB efficient, 200 Watts is likely plenty of power for you. If you only listen to light classical, jazz and don’t expect them to rock the house, 50 Watts is adequate. Higher efficiency speakers, like horns, take very few Watts.
Is 200 watts good for a stereo?
If the stereo you buy is the same as your car’s original factory stereo, you should be looking at 50 to 200 watts RMS of power. If you want to make your listening experience a little easier with an aftermarket receiver, though, you might want closer to 200 to 300 watts RMS.
