Product Type
Price Range
Number of Subwoofers
This value represents the number of subwoofers that the enclosure accommodates or that are included in the package or bundled kit.
Box Type
Represents the style of the enclosure. Be sure to purchase the appropriate enclosure type and internal volume that will be compatible with your subwoofer's recommendation.

Sealed - Sealed boxes are those that have no holes or vents in it. The only hole in a sealed box is where the subwoofer is installed. Smaller sealed boxes require more power than a larger sealed box. They provide a tight, accurate bass, while the larger sealed enclosures provide a "boomier" and louder bass.

Ported / Vented - Ported/Vented Enclosures provide an even boomier, louder bass, but less accurate then a small, sealed box. Ported enclosures typically require more airspace per sub and also less power output from an amplifier to perform correctly.

Bandpass - Bandpass enclosures make subwoofers perform efficiently, but loose. The bass is not as "boomy" as a ported enclosure nor as punchy as a sealed enclosure. Bandpass enclosures work well with lower to mid-level subwoofers.
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
Subwoofer Cutout Shape
This is the shape of the enclosures cutout hole and defines the style of subwoofer that can be installed.
Box Exterior Color
The color of the enclosure's exterior/outer finish.
Total Box Volume
The internal volume measurement in cubic feet before subwoofer magnet displacement.
Cutout Diameter or Length
The actual diameter of the hole in the subwoofer box. Length is the measured length per side of a square subwoofer or speaker opening.
Maximum Speaker Depth
Your subwoofer or speaker must not exceed this dimension in order to properly mount in this enclosure.
Box Style/Shape
The box style or shape refers to the actual shape of the box. Square and rectangular boxes are straight-edged boxes on all sides, whereas hatchback and truck style enclosures feature an angled front or back design that allows for installation in places short on depth such as single cab pickup trucks. You can also use such enclosures in hatchback cars or other vehicles where space is a premium. Tube and cylinder shaped boxes were made popular by Bazooka and are a great option for those looking for a nice amount of bass without sacrificing lots of space. They may even fit in locations that slim truck boxes cannot fit in. If the enclosure is vehicle specific, we encourage you to read the product description to find out which vehicles the enclosure is made for.

    Empty Car Subwoofer Enclosures & Boxes
    Empty Car Subwoofer Enclosures & Boxes Frequently Asked Questions (FAQ)
    An empty car subwoofer enclosure, also known as a subwoofer box or cabinet, is a specialized enclosure designed to house a subwoofer driver. Unlike pre-loaded enclosures that come with a subwoofer already installed, empty enclosures allow you to select and install the subwoofer of your choice. This gives you the flexibility to choose a subwoofer that best suits your preferences and audio needs. Empty subwoofer enclosures are available in various sizes and designs, such as sealed, ported, and bandpass, allowing you to match the enclosure type with your desired bass response. If you already have a subwoofer or prefer a specific brand/model, an empty enclosure is the perfect solution to ensure a custom-tailored audio setup with optimal sound quality and bass performance.
    Selecting the right size of an empty car subwoofer enclosure is crucial for achieving the best audio performance. The enclosure's size is typically determined by the subwoofer's recommended air space, as specified by the manufacturer. It's essential to match the subwoofer's requirements with the available space in your vehicle. Measure the area where you plan to install the enclosure, considering the depth, width, and height. Ensure that the enclosure fits securely and does not obstruct any other vehicle components. If you are unsure about the appropriate size, consult with a car audio expert or refer to the subwoofer's specifications provided by the manufacturer. Choosing the correct enclosure size ensures that the subwoofer operates efficiently, delivering accurate and powerful bass without distortion.
    While empty car subwoofer enclosures are designed to be versatile and accommodate various subwoofers, there are still compatibility considerations to keep in mind. The enclosure's size and design must match the subwoofer's recommended air space to ensure proper operation and sound quality. Some subwoofers may require a sealed enclosure, while others work best in a ported or bandpass design. It's essential to check the subwoofer's specifications to determine the ideal enclosure type and size for optimal performance. Additionally, consider the subwoofer's power handling capabilities and impedance rating to ensure it matches your amplifier's output and impedance load. If you have any doubts about compatibility, seek advice from car audio professionals who can recommend the best subwoofer options for your chosen empty enclosure.
    Using an empty car subwoofer enclosure offers several advantages over pre-loaded enclosures. First, you have the freedom to choose any subwoofer that suits your audio preferences and power requirements. This means you can select a premium-quality subwoofer or one with specific performance characteristics that match your desired audio setup. Additionally, empty enclosures allow for more customization in terms of enclosure type (sealed, ported, bandpass) and size, enabling you to fine-tune the bass response to your liking. Installing a subwoofer in an empty enclosure also allows for easier upgrades or replacements in the future without changing the entire enclosure. Overall, using an empty car subwoofer enclosure grants you greater flexibility and control over your car audio system, resulting in a personalized and optimized audio experience.
    The ease of installing an empty car subwoofer enclosure can vary depending on your experience with car audio installations and the complexity of your vehicle's interior. Basic installations, such as placing the enclosure in the trunk or rear cargo area, can be relatively straightforward for those with some DIY skills. However, more complex installations, such as custom mounting or integrating the enclosure into the vehicle's interior, may require professional assistance to ensure proper fitment and wiring. It's crucial to properly secure the enclosure to prevent any movement or rattling while driving. If you are unsure about the installation process or lack experience with car audio installations, seeking help from a certified car audio installer is recommended. They have the expertise and tools to install the empty subwoofer enclosure correctly, maximizing its performance and ensuring a seamless integration into your vehicle's audio system.

These enclosures are designed to house subwoofers of various sizes, giving you the flexibility to choose the subwoofer that best suits your desired bass response and power handling requirements.

    One of the main advantages of using empty car subwoofer enclosures and boxes is the freedom to select the type of subwoofer and amplifier combination that perfectly matches your audio preferences.
