Step 1 – Control the power

As mentioned earlier, your primary cause of concern with this DIY project is frying your woofer by running it on 110 volts, when it is designed to only run on the 12 volts generated by the battery of your car.

Thus, the first thing you must do when trying to convert your car’s subwoofer for home use is buying a power inverter that will enable you to control the power.

You need a power inverter that is capable of converting 12 volts, with 2 plugs: one plug for the woofer and the other for the wall outlet.

Although, you need to keep in mind that despite the fact that your first step is buying a power inverter, the last step will be plugging it.


Step 2 – Connect the subwoofer to the car amplifier

The next thing you need to do is taking a twelve- or sixteen-gauge speaker wire (this depends on the model of your subwoofer, so check the specifications of the manufacturer if you are unsure of which exact one to utilize).

Connect your subwoofer and amplifier to the wires.

The wires can be connected to the brackets beneath the terminals on the appliances. Keep in mind that the red wires must be twisted with red wires and the dark wires must be twisted with dark wires. Although, you may need to first strip the wires.


Step 3 – Connect the car subwoofer to the home amplifier

The next thing you have to do is connecting the wires to the input terminals of your car’s audio subwoofer, before connecting to the output terminals of your home amplifier.

For this situation, you will have to pair red with red and white with white.


Step 4 – Now connect your other speakers

You now finally have to connect the remaining speakers in the home system.

If you want to have a really powerful surround sound experience, two speakers are needed on the left, two speakers are needed on the right and one needed in the center.

Make use of RCA wires to connect these to the main amplifier of the home theater (home performance center principle speaker (however, keep in mind that this isn’t the amp the woofer is connected to)


Step 5 – Plug in the power inverter

As mentioned, while describing the first step, the last step involved is actually plugging the subwoofer into the power inverter and then connecting the inverter to the outlet on the wall. Afterward, play a couple of songs and get ready to have your neighbors banging on your door, either to join the party or complain about the loud music coming from your apartment.

Disadvantages of Using Your Car Subwoofer in House
