Which way to face subwoofer in trunk

Which way to face subwoofer in trunk? The direction in which a subwoofer in a trunk should face depends on several factors, including the size and shape of the trunk, the type of subwoofer being used, and the desired frequency response. In general, subwoofers can be placed facing forward, backward, upwards, or downwards in a trunk.

There are several ways to face a subwoofer in a trunk, each with its own pros and cons.

Facing Up:

Pros – more directional, the sound waves will hit the roof of the trunk first, providing more reflection and helping to distribute the sound more evenly.

Cons – takes up more space in the trunk.

Facing Down:

Pros – conserves trunk space, provides a more focused, punchy bass.

Cons – the sound waves will hit the trunk floor first, potentially causing some distortion and reducing the overall sound quality.

Facing Forward:

Pros – provides a balanced and directional bass, helping to fill the cabin with sound.

Cons – can cause the subwoofer to vibrate and potentially damage the car’s interior.

Facing Backward:

Pros – helps to conserve trunk space and provides a balanced bass.

Cons – the sound waves will have to travel through the back seat, potentially causing some sound quality degradation.

Based on the pros and cons of each orientation, it’s recommended to face the subwoofer forward or up for the best sound quality. Of these two, facing forward is generally considered the better option, as it provides the most balanced and directional bass.

The best position for subwoofer in the trunk

The best position for a subwoofer in the trunk of a car can vary depending on the car’s interior design and personal preference. Here are some common positions with their pros and cons:

Middle of the trunk:

Pros: provides an equal distribution of bass throughout the car, making it suitable for most music genres.

Cons: may not fit in smaller cars and can block access to other items stored in the trunk.

Corner of the trunk:

Pros: maximizes the available space for the subwoofer and provides a deep, powerful bass.

Cons: can cause the bass to sound boomy and overpower the other frequencies.

Behind the rear seats:

Pros: provides a tight, accurate bass, especially in sedans with ample space behind the rear seats.

Cons: can affect rear passenger comfort and block access to the trunk.

Under the rear deck:

Pros: provides a clean, integrated look and saves trunk space.

Cons: may not provide enough space for larger subwoofers and can affect the overall sound quality.

Ultimately, the best position for a subwoofer will depend on the individual car and personal preferences. Experimenting with different positions and fine-tuning the subwoofer’s placement and settings can help achieve the desired sound.

Why should I place a subwoofer in trunk?

Placing a subwoofer in a trunk has several advantages, including:

Improved Sound Quality: Trunk placement allows for a subwoofer to have more room to produce deeper, stronger bass tones.

Increased Volume: Placing a subwoofer in the trunk provides more space for air to move, resulting in increased volume and overall sound output.

Customizability: Trunk placement allows for more flexible subwoofer placement options, allowing for a better fit for different car models.

Better Integration: Trunk placement can help to integrate the subwoofer more seamlessly into a car audio system, as the subwoofer is not visible from the inside of the car.

Better Sound Isolation: Trunk placement helps to reduce the amount of bass that enters the cabin of the car, which can result in improved sound clarity for the listener.

How can I make my subwoofer sound better in my trunk?

Here are some tips to improve the sound of your subwoofer in your trunk:

Positioning: Place the subwoofer in the center of the trunk for balanced sound distribution.

Sealing: Make sure the trunk is sealed properly to prevent sound leakage.

Insulation: Use sound-deadening material such as mats or foam to reduce road and engine noise.

Amplifier: Make sure the amplifier provides enough power to the subwoofer.

Crossover: Use a low-pass crossover to filter out higher frequencies that the subwoofer can’t reproduce accurately.

EQ: Use an equalizer to adjust the subwoofer’s frequency response and fine-tune the sound.

Wiring: Make sure the wiring is done correctly to avoid electrical interference and ensure maximum power transfer.

Volume: Set the subwoofer’s volume and crossover point carefully to avoid overloading or damaging the subwoofer.


The best way to face a subwoofer in a trunk depends on several factors, including the size and shape of the trunk, the type of subwoofer being used, and the desired sound quality. In general, it is recommended to face the subwoofer forward, towards the rear of the vehicle, for a balanced and well-defined bass sound. However, some enthusiasts prefer to have the subwoofer face upwards or towards the side for a more powerful bass that emphasizes the lower frequencies. Ultimately, the best orientation will vary based on the individual’s specific needs and preferences.
