How to Connect Subwoofer to Car Stereo? [Step-by-Step]

No matter what kind of music you like to listen to, adding bass makes everything better.

So, have you recently upgraded your car sound system with a subwoofer?

Are you excited to go on a long trip with your friends while playing your favorite playlist at a loud volume that almost shatters the windows, but you don’t care because the excitement is next level, right?

But wait, did you happen to think about the connection process? Yes, the hard part of installing the best car subwoofer at the right place may be over, but you need to know how to connect a subwoofer to the car stereo while retaining your controls.

This article will walk you through the easiest process of connecting this pretty energy-consuming device to your car stereo. However, connecting the device to your car stereo is different for both passive and powered subwoofers, and we will discuss both types in detail. Let’s start.

Connect Powered Subwoofers to Car Stereo

As with a regular amplifier, the powered subwoofer plugs into the audio system’s auxiliary input. This is a simple procedure, and most active woofers already have the wiring you’ll need to get started:

Step 1: Disconnections

Before beginning to connect a subwoofer to a car stereo, never forget to disconnect the ground wire from the battery.

Step 2: Gather the Pieces of Equipment

You may need some tools while connecting a sub.

  • Tester
  • Screwdriver
  • Pliers
  • Hammer

Step 3: Battery Power

We can’t just rely on the engine for our power needs as the sub requires more stable power; we have to have a backup battery. It guarantees that more power is sent to the vehicle. Once it enhances the current flow and boosts the subwoofer’s signals, we can connect rear speakers as a subwoofer output.

Power the subwoofer from the automobile battery. The main power fuse must be near the battery. Run the power cord under the carpet to prevent damage.

Step 4: Remove the Car Stereo

To obtain access to the wiring harness and outlets on the stereo’s back panel, you will need to detach the stereo from its mounting dock in the vehicle. Be very careful as you have to attach it back.

Step 5: Run the Wires

Connect the car subwoofer to the RCA signal cables that come from the car stereo. The RCA wires should be routed underneath the carpet in the same manner as the power wire. Keeping the RCA and power cables separate is important because they may distort the sound and cause a disturbance.

Step 6: Metal for Subwoofer Ground

Install a subwoofer with its ground connection in the trunk of the vehicle. Make sure that you connect metal to metal and that there is no paint in the way of the connection between the vehicle body and the wire.

Step 7: Some Testing

If there is a control wire with the subwoofer, you will need to run it from the woofer to the location where you will be using it. It may be located on the dashboard or close to your seat. Just make sure that the control panel for the steering wheel will be simple to operate and will not interfere with your driving in any way.

Step 8: Connect Ground Battery Wire

After completing all of the connections, reattach the ground battery wire that had been removed earlier by screwing it back onto the battery’s negative terminal. Ensure a stable and secure connection flow.

Connect Passive Subwoofer to Car Stereo

A passive subwoofer, also known as a speaker with no built-in amplifier, can be linked to the car stereo in the same way you connect any other speaker to your car.

If you already have a complete setup of speaker wires where you will be putting the subwoofer, connect them with a subwoofer wire, and that’s it. You can run the subwoofer and enjoy the low frequencies to boost your music-listening excitement.

However, if there is no wiring for the speakers already installed, you will need to run wires from the head unit harness like you would run wires for the car speakers.

Make sure to disconnect a ground wire from the car battery to save the gear and yourself from facing any unfortunate event.
