What does 50W x2 100W mean?
50W x 2 +100W means the maximum power delivered to the Loudspeaker. 50W to the Left speaker, 50W to the Right speaker and 100W to the Subwoofer.
How is amp capacity calculated?
Power = Voltage squared divided by Resistance. With a constant sine wave input, you measure 10 volts AC on the speaker output of the amplifier. Since you know the resistance (5 ohms) and the voltage (10 volts), you can calculate the power: Power = (10 times 10) divided by 5 = 100/5 = 20 watts.
What is the difference between 50W and 100W speakers?
The same thing holds true at higher wattages—a 100W amp is not going to sound twice as loud as a 50W amp; assuming identical speakers, it will only be 3 dB louder, which is noticeable, but definitely not a doubling of perceived loudness.
How do you match speakers to amplifiers?
Generally you should pick an amplifier that can deliver power equal to twice the speaker’s program/continuous power rating. This means that a speaker with a “nominal impedance” of 8 ohms and a program rating of 350 watts will require an amplifier that can produce 700 watts into an 8 ohm load.
How do I know what amp to get for my subs?
Step 1: How much power? Find out the “watts RMS” rating of the sub. Then, multiply the number of subs you have by the RMS rating of each, to get their total RMS rating. You want to make sure the amp you choose will supply no more than the sub system’s total RMS rating.
How loud is a 50 watt amplifier?
For music, 50 watts is pretty good. Just turn it down a bit, if it sounds a bit harsh. 200 watts isn’t going to give you a ton more headroom, see above. If you really want rock concert levels, go buy a pro amp, like from Crown audio or Peavey, or a good home audio amp like Outlaw or Emotiva.
Is 160 watts loud?
160 watts through a 15″ speaker won’t be perceivably as loud as the same through, say, 4 10’s. i had like this 200w lightbulb once it hummed pretty loud.
