Ensure your turntable has the necessary outputs to connect to a subwoofer or an amplifier if you’re using one.

Gain Control

Some turntables offer gain control, allowing you to adjust the volume of the audio signal sent to the subwoofer.

This can be useful for balancing the sound between your turntable and subwoofer.

Speed Settings

While not directly related to the subwoofer connection, the speed settings (33, 45, or 78 RPM) can affect the audio quality and bass response.

Check that your turntable is set to the correct speed for the record you’re listening to.

Ground Wire

Some turntables come with a ground wire to eliminate hum or noise.

If your setup includes an amplifier, make sure to connect the ground wire to the amplifier’s ground terminal for a cleaner sound.

Built-in Phono Preamp

If your turntable has a built-in phono preamp, you have the flexibility to connect it directly to a variety of audio equipment, including subwoofers with line-level inputs.

Troubleshooting Common Issues With Subwoofer-Turntable Connection

Even with the best preparations, you might encounter some issues when trying to connect a subwoofer to a turntable. Here are some common problems and their solutions:

No Sound from the Subwoofer

If you’re not getting any sound from the subwoofer, the first thing to check is your RCA cables.

Make sure they are properly connected to the correct outputs and inputs on your turntable and subwoofer or amplifier.

Distorted Sound

If the sound from the subwoofer is distorted, it could be due to incorrect crossover frequency settings.

Try adjusting the crossover frequency on your amplifier or subwoofer to better match your audio system.

Suboptimal Subwoofer Position

The position of the subwoofer can significantly affect your listening experience.

If you’re not happy with the sound, try moving the subwoofer around the room to find an optimal spot.

The goal is to evenly distribute the bass throughout the room.


To fix the humming sound, try plugging both the turntable and subwoofer into the same power outlet or power strip.

If this doesn’t work, you may need to purchase an isolation transformer or a wireless subwoofer transmitter.


If you notice a buzzing sound coming from your subwoofer, try connecting the ground wire from the turntable directly to the amp chassis.

If this doesn’t work, you may need to use a meter to diagnose the problem.
