How many watts RMS do I need?

An aftermarket receiver — you might want 200 to 300 watts RMS of power for your sub. Amplified speakers with around 50 watts RMS per channel — plan on 250 to 500 watts RMS for bass. A 100 watts RMS or higher per channel system — you’ll want at least 1,000 watts RMS for your sub.

Should Amp RMS be higher than speakers?

It’s OK to use an amp that’s rated at the same RMS as the speakers (which is sometimes useless since no two companies use the same methds), but it’s actually safer to get one slightly higher. As long as you don’t put a 150 watt RMS amp on a 50 watt RMS speaker. :shrug: You don’t want to do that.

How do you calculate RMS for amps?

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.

Is more RMS watts better?

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.

Is 30W 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 happens if amp is too powerful for speakers?

Amplifiers can be too powerful for speakers. Speakers are limited by the electrical energy that they can convert into audio. As a general rule, if the amplifier produces more electrical energy than the speakers can handle, it may cause distortion or clipping, but damage is unlikely.

What size fuse do I need for a 1500 watt amp?

150 Amp
A 2500 watt uses a 250 Amp fuse, while a 1500 watt uses a 150 Amp fuse.
