  • How many watts do I need in my car? - Tempotopaz.com

    How many ohms are car stereo speakers? Impedance of Car Speakers In car audio, 4-ohm speakers are the norm. That's because car audio systems run on 12 volts DC instead of a 120 volts AC. A 4-ohm impedance allows car audio speakers to pull more power from a low-voltage car audio amp. Car audio amps are designed for use with low-impedance speakers.

  • Can you use a voltmeter to determine Watts to a speaker

    Mar 10, 2021 · Doubling the wattage input into the speaker will result in approximately 3dB of volume increase. In this case, 2 watts of power results in 88dB, 4 watts of power will produce 91dB, and so on. At 10 watts of power, you would be producing about 96dB of volume. That's about as loud as a jackhammer from 50 feet away.

  • How Much Amplifier Power | Crown Audio - Professional

    A speaker's peak power handling is typically 4 times its continuous power handling. So the speaker can probably handle 1000 watts peak. That means you can use a 1000 watt amplifier to drive that speaker -- as long as you use that power for peaks, and do not drive the speaker continuously with 1000 watts.

Therefore with for a speaker of any given power rating it would seem that max voltage could be determined by the formula: V = sqrt(P * R) Therefore for an 8ohm speaker with a power rating of 10 watts, it would seem that max voltage is around 9 volts. (sqrt(8 * 10 = 80) = 8.944 ~= 9)

    Sep 15, 2014 · This is equivalent to a sinewave amplitude of 1.265 volts RMS or about 3.6 volts p-p. If you used a push-pull circuit and a capacitor decoupler, a 1 watt speaker at 8 ohms impedance could be expected to handle about 2.828V RMS or 8 volts peak to peak. The better circuit would be about 7dB louder and have less distortion.

  • Is a speaker of 300 watt rms 3 times louder than that of

    No. The rating of a speaker is power handling and is pretty much useless. So, this is logarithmic. Your speaker has a rated efficiency; let's assume 87db/w. That means with an input of 1 watt (2.83 volts), measured from 1 meter away, playing a 1,000 Hz tone, your speaker will produce 87db. Increase to 2 watts and you get 90db.
