2 Ohm vs 4 Ohm Subwoofer: What Are The Differences?

Music is an indispensable part of life, so many people prioritize choosing quality equipment to have comfort when listening to music. You will need a subwoofer with low volume. 

Two of the favorite products in this area are the classic 2 Ohm vs 4 Ohm subwoofers, where ohms is a resistor that represents the ability to hold power and the level that can make a sound.

Some people will have difficulty choosing and evaluating the difference between these devices. The article helps you find the fastest and most accurate answer.

Many experts and users rate the 2 Ohm Subwoofer as a powerful subwoofer. It works with audio systems with more current, resulting in larger loads and increased power output.

A 2-ohm Subwoofer can produce a louder sound, suitable for large spaces and with many audiences. It means that if you give it more current, it will have a more audible sound.

Therefore, if you want good sound quality with high volume, a 2 Ohm subwoofer will fulfill all your aspirations.

What Is A 4 Ohm Subwoofer?

From the name of the 4 Ohm device, it is easy to see that it has a higher resistance. At the same time, the device needs to use less energy to operate. Therefore, the life and durability will be better than the lower resistance type.

The sound that a 4 Ohm device produces is somewhat limited in volume but superior in quality. You can quickly get this product for your car or house for $20 to $180. It will largely depend on the brand you want to have.

Which Is Better Between A 2 Ohm And 4 Ohm Subwoofer?

Sound Quality

If you experience both subwoofers, you need to check for more than one factor.

While 4 Ohm is the perfect solution for a smooth period when hitting tunes, the volume produced by the sound system is quite loud. It means that the 2 Ohm has a low resistance, and the output power represents its power.

The answer to which type of product is better will largely depend on what you like and expect.

A 2 Ohm device will be a perfect and ideal device when placed in a large room, and you want everyone to hear the sound coming from it. The 4 Ohm type was born for rooms with a smaller space or often placed in cars.


Price is an essential factor for everyone before deciding to own a product or use a service. Therefore, it means that the cost to purchase audio equipment is necessary to consider.

People give preference to products with lower costs. But you also need to pay attention to the quality and value they bring to you.

The 4 Ohm vs 2 Ohm subwoofers don’t have much price difference, and the 4 Ohm is more reasonably priced. The difference lies in the brand you use and its features. The average price to own a product ranges from $20 to $200.

If you own a cheap product, you need to take care of it more than a good piece of equipment.


In theory, a 2 Ohm device takes more current, so the system fails. At this time, the amplifier must be overworked because it has a low source resistance that leads to overload and is easy to explode. 

The top famous brands are equipped with systems to help limit this situation. You also need to consider the material. If it looks cheap, you should not buy it because of its quality and safety.

What Is Breaking In A Subwoofer And Is It Necessary?

Breaking into the device will help loosen the device’s suspension. It also allows you to improve overall performance and bass output.

Moreover, it will help increase the durability and extend the life of your device.

Can you run a 2 Ohm subwoofer at 4 Ohms?

Running a 2 Ohm load with the same amplifier at a 4 Ohm load can cause the potential power to drop markedly by up to 50% of the potential energy.

It will have the same problem if you do the opposite of running a 4 Ohm load with the amplifier at a 2 Ohm load.
