What is a Subwoofer?

There is a frequency for every noise in the world. The frequencies of higher-pitched sounds are higher, etc. Low-frequency sounds are difficult to recreate with standard speakers and immersive sound systems. A lot of music and films sound flat as a result of this.

A subwoofer (or “sub“) is a speaker that concentrates on producing lower frequencies in music, such as bass and sub-bass, which the speaker enhances.

While normal voices can make the bass audible, a subwoofer helps the audience to experience the bass. Instrumentation such as bass guitars, violins, and kick drums are highlighted in the frequency range of 20 and 200 hertz.

How to Powering the Car Subwoofer at Home

Here’s your solution to powering the car subwoofer at home. It’s not difficult to power a car subwoofer, but you’ll need to put in some effort to get it to work. To make your automobile woofers powerful at home, follow these easy instructions.

If you have a car subwoofer and want to connect it with your home theatre, you can take a few simple steps.

Easily switch your AC voltage at home into DC voltages using a computer power supply or any AC to DC converter to run a car subwoofer at houses.

As you may be aware, the subwoofer in your car is powered by a battery that supplies 12 volts to your entire audio system. Our house, on the other hand, has an AC of 110 volts or greater.

Obtaining a Power Inverter is the First Step:

Purchase a power inverter as the initial step. A power inverter turns the large current (120 volts) in your household outlet into the desired current (12 volts) required by your woofer.

There are two plugs on it. One is for your subwoofer, while the other is for an outlet. You must first purchase the power inverter, but that is not the end of the process.

Connecting Car Subwoofer and Amplifier Together:

The next step is connecting the car subwoofer and amplifier. Depending on the specifications of your woofers, you’ll need 12 or 16 gauge speaker cables for this connection. Again, to discover more about the specifications of your subwoofer, consult the handbook.

Connect the cables to the appliance brackets now. To make a secure connection, strip the wire and twist the red wire with the red one and the darker wire with the darker one.

Check Connected To The Home Amplifier:

Check Connected To The Home Amplifier:

After you’ve secured your subwoofer and car amplifier, you’ll need to connect the car amplifier to your home sound system’s main amplifier.

Connect the input terminal of your car’s subwoofer amplifier to the output terminal of your main amplifier for this reason. Make sure the red wire is connected to the red wire, and the white wire is connected to the white wire. This step is required to connect the automobile subwoofer to your home audio system.

Adding Additional Speakers:

After you’ve connected the amplifiers, you’ll need to connect your home sound system to some of the greatest center speakers. Make sure the extra speakers are connected to your house sound system’s primary amplifier, not your cars.

Five speakers are required to create a great sound system. Place two of the finest outdoor Bluetooth speakers on the left, two on the right, and one in the middle. This connection also necessitates the use of RCA cables.

Connect Power Inverter:

Finally, your car subwoofer will be integrated into your home audio system. Connect one of the power inverter’s plugs to your car subwoofer and the other to a residential outlet. Your automobile subwoofer is now ready to be powered by a standard domestic outlet.

Is it 100% Safe to Power a Car Subwoofer from your Home?

No, it isn’t a safe practice, particularly when you’re doing it yourself, because it could blow one of your audio components. However, if you choose to do it alone, be prepared to face the consequences if something problem occurs.

Making a car subwoofer part of your home sound system requires a great deal of consideration. Any incorrect connection can cause the entire system to fail.

Connect all of the wires in the proper locations and tighten all of the connections. So, if you want to use your automobile subwoofer at home, make sure you pay attention to all of the connections.

Most automotive subwoofers are designed to operate at 12 volts, which is insufficient compared to the power supply in your home outlets.

Your domestic outlet offers 120 volts AC, which is too much for your automobile subwoofer, which requires only 12 volts. If you plug your automobile subwoofers directly into a residential outlet, they may explode.

To decrease the energy and make your automobile subwoofer function at home, you’ll need DC power.

Drawbacks of Using a Car Subwoofer at Home

Drawbacks of Using a Car Subwoofer at Home

The only negative is that you will have to spend a significant amount of time completing this task. Buying all of the necessary equipment to power a car woofer is an expensive task.

You may have to spend $40 or more to power your car subwoofer, whereas a home subwoofer costs only $50. This may appear to be a bit pricey, but if you want to utilize your car subwoofer regularly, go ahead.

The very first downside of using your automobile subwoofer in your home is that if done incorrectly or if something goes wrong, you risk blowing up your entire system.

Sadly, there is no assurance that it would all work smoothly, so be prepared to face any scenario if you choose to convert your car woofer to a house subwoofer.

Furthermore, because there are so many things to buy while attempting to accomplish this shift, it is always incredibly costly in the long run.

For example, imagine investing around $40 to customize your automobile subwoofer for home use when reasonably used house subwoofers are around $50? Sometimes it just doesn’t seem rational to spend that much money on a project like this.

Finally, please remember that the intensity of the sound produced by your new apartment subwoofer will be affected by the materials utilized, which might work in both directions.

Does Using Car Subwoofer at Home Costs A Lot?

The majority of typical subwoofers are priced between $100 and $200. Many will come with an enclosure, although large speakers in this price point can also be found without one. Over $200, you’ve entered the realm of entire automobile subwoofer packages.

Subwoofers are costly due to their features. However, the higher cost is attributable primarily to the electronics sector’s specialist nature. Because only a few customers buy this equipment, producers have difficulty trying to recoup their investment.

Installing a subwoofer costs roughly $100, but more extensive installation work can cost over $300. Even better, buy some or all of your parts, such as the subwoofer, from a vendor who will also build it for you as part of the arrangement.


Final Note

There is nothing wrong with hooking up your automobile subwoofer to a home theatre or using it for house functions. However, there are certain disadvantages.

The sound will be of inferior quality, and you’ll need additional equipment to make it all work. However, if you don’t have any other options, this is a viable solution. If you’re not too familiar with the technology, there can be setbacks to powering a car subwoofer at home. It can even be dangerous, but if you have a basic idea of what you’re doing and follow the instructions, you’ll be able to do it without facing many difficulties.
