Actually, many car subwoofers are designed to work better with home stereos and deliver the best quality bass performance than home subwoofers. Therefore, many music enthusiasts prefer to power up their home audio system with the car subwoofer for extra punch.

Let’s get into the details about how to use your car subwoofer at house and what factors to consider before getting into this business. 

How to Power a Car Subwoofer at Home?

The power supply in the home sockets is far too much than the car subwoofer can handle. Yes, subwoofers for a car are designed to work at 12 Volts (DC), whereas the house sockets usually provide up to 220 volts (AC), so if you power up the device with them, it will blow up. 

In this case, you need DC power to lower the house socket power, so you can easily run the car subwoofer at home without exploding. It will manage the power running and provide the necessary voltage to the subwoofer while filtering out the remaining. Hence, it is the only and safest way you have to power a car subwoofer at home. Let’s see how you can do it in an easy way.

Step 1: Power Inverter

You must have heard about the power inverter, right? 

It will be the safest purchase you could make to turn this car device into one to use at home. It will convert the high current into the desired current, which is only 12 volts that your subwoofer requires to power up. 

It would come with two plugs, one has to attach to the subwoofer, and the other will go into the outlet. But that’s not the only issue you need to worry about. 

Step 2: Subwoofer to Car Amplifier Connection

Now let’s make some connections, and you might do some complex wiring in this step.

Connecting a subwoofer to a car amplifier is next in the line; for that, you will need 12 or 16-gauge wires (according to your subwoofer) and connect both devices by finding the brackets beneath the terminals. 

However, you must strip the wires and ensure the red ones must twist with the red wires and black to the black ones. In this step, know that your subwoofer and car amplifier are connected. 

Step 3: Car Subwoofer to Home Amplifier Connection

A little more work with wires here. Now, in this step, locate the car subwoofer amplifier’s input terminal and connect it to the output terminal of the main home amplifier. It will connect the car subwoofer to the home audio system, but ensure the red cable connects with the red ones and the same with the white. 

One wrong move with the cables can put your car subwoofer and home audio system in danger, so you better be careful with that. 

Step 4: It’s Time to Connect the Speakers

Both your devices are now connected, and you are set to connect the other speakers to get the party going. 

According to your home audio specs, you can pair speakers at the front, rear, and side to have a rich surround sound experience. The car subwoofer will perform with full authority and deliver a hard-hitting, deep, and rich bass while blending with the mid and high-level notes. 

Step 5: Power up the Subwoofer

Let’s remember the first step where we mentioned the power inverter comes with two plugs, right?

Connect one plug of the inverter to the car subwoofer and a second to the outlet in your home. Turn on the sound system, play some music, and enjoy the banging bass with the next-level clarity and excitement in your house.

Disadvantages of Using a Car Subwoofer at Home 

Every technology-oriented device comes with its own pros and cons. Where it can save you space and cost while offering a heart-pounding, distortion-less bass at your comfort place, it also raises questions about safety and other stuff. Let’s discuss the risks you are bringing with the car subwoofer at home. 

  • Car subwoofers have much lower impedance than those used in home entertainment systems. So, matching and satisfying the power consumption of a subwoofer with amplifier power output demands much attention. And if both devices have a variance, you better think twice. 
  • You may have to purchase lots of equipment to get the task done. And if you are not into technology or electronics, you may need to hire professional help. 
  • Any wrong connection attempt can blow the subwoofer, speaker, and entire sound system.
