Can you add an amp to a powered subwoofer?

Can you add an amp to a powered subwoofer? 

While a powered subwoofer (active subwoofer) does not need to be connected to an amplifier since its amp is built-in, you can connect a powered sub to an amp for data transmission only. To do this, connect the two with RCA cables and plug the powered sub into the wall for its power source.

How do you replace a subwoofer amp? 

Do you need an amp for a powered subwoofer? 

Whether a subwoofer is passive or powered isn’t the determining factor on how good the subwoofer is. However, Powered subwoofers are by far the most commonly used as they have their own built-in amplifiers and are not dependent on any amplifier limitations of another receiver or amplifier.

How do I know what amp I need for my sub? 

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.

Can you add an amp to a powered subwoofer? – Related Questions

Should amp be bigger than sub?

An amp need not be bigger than a sub as long as its capabilities evenly match the sub’s specifications. However, it’s always better to get an amp that puts out a bit more power than your sub, especially if it’s a passive sub. If you have an active sub, you may not even need an external amp at all.

What size amp do I need for a 1200 watt sub?

You can run a “1200w speaker” with a 10 watt amp.

What if my amp is more powerful than my 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.

How do I match my speakers to my amp?

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.

What size amp do I need for 2 1000 watt sub?

For a 1,000 Watt powered sub, you would need about 10 Amperes at 120 Volts, assuming digital amplification.

What hits harder 2ohm or 4ohm?

In terms of which subwoofer hits harder, drawing from the explanation as given above, the 2-ohm subwoofer produces a louder sound than the 4-ohm subwoofer. So in that sense, technically speaking, the 2-ohm subwoofer hits harder than a 4-ohm subwoofer.

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.

What class amp is best for subs?

The very best amplifier for a subwoofer is a class AB or Class H amplifier. Class D amplifiers are too slow and cannot keep up with repetitive bass. A class AB has a toroidal transformer and coke can capacitors so when the kick drum kicks the woofer responds instantly. Buy the power amp that matches the subwoofer.

What does class D mean on a amp?

A class-D amplifier or switching amplifier is an electronic amplifier in which the amplifying devices (transistors, usually MOSFETs) operate as electronic switches, and not as linear gain devices as in other amplifiers.

What does Class D subwoofer mean?

Class D amps, also known as “digital” amplifiers, work by shifting the sample frequency at which they operate up to extremely high frequencies. In doing so, they use MUCH smaller power transformers which takes up far less interior space—something that is always at a premium in subwoofers.

What is better Class A or Class D amplifier?

Class A design is the least efficient but has the highest sound fidelity. Class B design is a little more efficient, but full of distortion. Class AB design offers power efficiency and good sound. Class D design has the highest efficiency but isn’t quite as high-fidelity.

What are class AB amplifiers used for?

The basic purpose of a Class AB amplifier is to preserve the basic Class B configuration while at the same time improving its linearity by biasing each switching transistor slightly above threshold.

Are Class A amplifiers the best?

Class “A” amplifiers are considered the best class of amplifier design due mainly to their excellent linearity, high gain and low signal distortion levels when designed correctly.

Why do Class A amplifiers sound better?

If in a decently engineered version of either distortion is low enough, then it is inaudible. If it is higher and then audible, then class A may sound better as more even harmonics due to no crossover distortion.

What is the difference between a Class A and Class B amplifier?

Class A amplifiers can be made very linear, but with limited efficiency. In theory, a class A amp can achieve 50% efficiency with inductive output coupling or 25% with capacitive coupling. Class B amplifiers are subject to “crossover” distortion, but efficiency runs theoretically as high as 78.5%.

Why are class A amplifiers so expensive?

Manufacturing costs between mass production and handmade exemplars differ dramatically. Good amps are so expensive because of common beliefs in what is good. As the result, mass produced amps contrary to common beliefs are bad, while really good amps are made in low quantities.

What is class H amplifier?

Class-H amplifiers create an infinitely variable (analog) supply rail. They are sometimes referred to as rail trackers. This is done by modulating the supply rails so that the rails are only a few volts larger than the output signal “tracking” it at any given time.
