# What are RMS watts?

by Alison Hoffman | views: 137

Root mean square or simply RMS watts refers to continuous power handling of a speaker or a subwoofer or how much continuous power an amplifier can output. RMS values are usually lower than peak watts ratings, but they represent what a unit is truly capable of handling.

# of SpeakersEach Speaker Rating (RMS)Recommended Amplifier Power (RMS)
1100 watts30-100 watts
2100 watts60-200 watts
3100 watts90-300 watts
4100 watts120-400 watts

With that in mind, how many rms is 1000 watts? The figure you're looking for is what the amp can do RMS at 4 ohms and that's what the wattage is for your amp. In this case, about 1000 watts RMS, SSL's website rates it at 1250 RMS.

Adding to that, what does rms power mean? The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. RMS power is derived from Root Mean Square which is a statistical measurement of the magnitude of a varying quantity and is applied to voltage or current.

What does 150w RMS mean?

RMS stands for Root Mean Square. It's a math term that describes the average output of a speaker over time. For example, 150w RMS means a set of speakers can comfortably play 150w over several hours without a problem. Peak power is the maximum theoretical output of a speaker.

##### Does RMS mean louder?

Root mean square is a measurement of how strong an electric current is, with higher RMS power generally meaning more powerful sound.

##### What is a good RMS for a subwoofer?

It is recommended that you go with at least 100 watts RMS in order to get a decent amount of power for your subwoofer. This will make sure that your speakers are loud and clear, but it can be improved by using an amplifier as well.

##### How many RMS is 3000 watts?

Assuming the standard 50% less power for RMS ratings, the 3,000-watt amplifier as advertised really only has around 300-watts of RMS output.

##### How do you calculate RMS on a speaker?

RMS Power:

When measuring a pure sine wave, RMS voltage can be calculated by measuring the peak voltage level and multiplying it by 0.707. This value can then be used to calculate RMS power.

##### What is 200 RMS in watts?

200 watts RMS is per pair of speakers (100 watts each speakers + 100 watts each speaker) this is the REAL power of this speakers. In summary each speaker has 100watts of RMS power (REAL power).

##### Is more RMS watts better?

RMS values are usually lower than peak watts ratings, but they represent what a unit is truly capable of handling. Think of RMS power as the average power that a speaker can handle on a daily basis without compromising sound quality or experiencing any distortion.

##### How much over RMS can you go?

When you look for an amp for your subs, you will need about 15-20% of headroom. Headroom is extra power above the combined RMS. If your subs are 300 watts RMS combined, then you need 345-360 Watts RMS to have safe headroom. If you go above that, then you will overpower your subs, and damage them.

##### Why is RMS useful?

The RMS value is the effective value of a varying voltage or current. It is the equivalent steady DC (constant) value which gives the same effect. For example, a lamp connected to a 6V RMS AC supply will shine with the same brightness when connected to a steady 6V DC supply.

##### Is 60W RMS loud?

They are too loud in small room, but usually you can't crank up the volume to maximum without distortion, and the small size does not properly "fill" the room. 60W (30W per speaker) is not really adequate though it will probably give you a reasonable background noise. Just likely not overly loud.

##### What is 250w RMS?

RMS power handling refers to how much continuous power the speaker can handle. A speaker with a 30W RMS rating but a peak rating of 60W will be able to run with 30 watt continuous power with occasional bursts of up to 60 watt.

##### What's a good RMS for speakers?

RMS ratings realistically measure how much power the speaker can handle on a continuous basis, not just for a short period of time. A speaker rated at "up to 50 watts RMS" will make a better match for your low-powered stereo than another speaker rated "10-80 watts RMS."

##### What is a good car speaker wattage?

If your car stereo has an RMS wattage that is twice as much as the amplifier power output, then it would put out a clean and clear sound. Anything over 60 watts per channel is usually enough for most vehicles, but if you want to hear music at its best quality, 100-watts or more might be needed.

##### Do more watts mean louder subwoofer?

Yes, it's true that the higher the power (watts), the louder and cleaner the speakers will play. Small differences in power, however, don't make much of an audible change. In order to perceptively hear a difference (a 3dB increase), the power would have to double.

##### Is peak power or RMS more important?

RMS values are typically much lower than peak power ratings, but they more accurately represent what an amplifier or speaker is truly capable of. Think of RMS as a true listening rating. Although not a perfect means of comparison, most RMS ratings are comparable – especially when measuring among name brand products.

##### What subwoofer has the deepest bass?

• #1 Rockford Fosgate P300-12 – Best Car Subwoofer for Deep Bass.
• #2 Pioneer TS-WX130DA – Best Enclosed 8-inch Sub for Deep Bass.
• #3 Kicker 44CWCS124 CompC – Best Low Bass Subwoofer.
• #4 Rockford Fosgate P3SD2-8 – Best 8 inch Deep Bass Subwoofer.
• #5 Skar Audio ZVX-15v2 – Best Bass Subwoofer for Car.
• ##### What if my amp is too powerful for my sub?

Turn the deck up with the amp gain at/near minimum till the speakers distort or you reach your "loud" listening volume. Now raise the gains on the amp till either the sub distorts or you achieve the amount of bass you desire. You'll have to tweak it a bit further likely, but this will get you in right area.
