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.
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
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.
Type of Enclosure
Some of our Vehicle Specific enclosures are loaded with a subwoofer and an amplifier, some are only loaded with a subwoofer, while some are empty boxes.
Total Peak Power Handling
This is the Total Peak Power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total peak power handling for all of the subs combined.

Peak power handling refers to the amount of power a speaker can handle during a brief musical burst. The RMS power range figure is a much more reliable rating for determining the speaker's power requirements.
Total RMS Power Handling
This is the total RMS power handling of all the subwoofers included in the package or enclosure.

If the loaded enclosure or amplifier and subwoofer package includes more than a single subwoofer, then this is the total RMS power handling for all of the subs combined.

The RMS power is the amount of power the speaker requires to operate safely and properly. RMS Power Handling refers to the amount of power a speaker can handle on a continuous basis. We recommend giving your subwoofer(s) 75% - 90% of the recommended RMS rating.
Deals
Promotions we have offer More Ways to Shop for items that are on clearance, last chance, special offer and sales, Made in America, and more!
Final Wired Impedance
This is the final impedance of the system as the amplifier will see it. If the final impedance is for two sets, it means that the enclosure has two sets of terminals at the listed impedance.
Box Finish
The material used on the outside of the box. Most boxes are carpeted to prevent exterior scratches; however vinyl is popular as it can often be color-matched to a near exact look of your leather factory interior.

    FAQ Frequently asked questions in All Custom-fit Subwoofer Boxes

    Custom-fit Subwoofer Boxes Frequently Asked Questions (FAQ)
    Custom-fit subwoofer boxes are specially designed enclosures that are tailored to fit specific vehicle makes and models. These boxes are crafted to utilize the available space in your vehicle most efficiently, ensuring a seamless integration that doesn't sacrifice valuable trunk or cargo space. They provide several advantages, including optimal bass response, enhanced audio quality, and a polished, factory-like appearance. By choosing a custom-fit subwoofer box, you can enjoy a clean and professional-looking installation that complements your vehicle's interior while delivering impressive bass performance. These boxes eliminate the need for complex fabrication work and customization, making them an excellent choice for those seeking hassle-free, high-quality bass solutions.
    Determining the availability of a custom-fit subwoofer box for your vehicle is straightforward. Most reputable manufacturers and retailers provide online tools or compatibility guides. You typically input your vehicle's make, model, and sometimes the year, and the tool will display compatible options. Alternatively, you can reach out to the manufacturer or retailer directly for assistance. They can verify compatibility and guide you in selecting the appropriate custom-fit subwoofer box for your vehicle.
    Custom-fit subwoofer boxes are designed with ease of installation in mind, making them suitable for DIY enthusiasts. They come with clear instructions and mounting hardware, simplifying the installation process. In most cases, you can secure them to the vehicle using basic hand tools. However, the level of installation difficulty can vary depending on your vehicle's make and model, your technical expertise, and the complexity of your audio system. Some installations may require minor modifications or the removal of existing components. If you're not comfortable with these tasks, or if your vehicle has unique challenges, it's advisable to seek professional installation. Professionals can ensure a secure and seamless integration while avoiding potential issues.
    While custom-fit subwoofer boxes are designed to accommodate various subwoofer sizes and styles, it's essential to choose a subwoofer that matches the box's specifications and your audio preferences. Consider factors such as the subwoofer's size, power handling, and impedance. Ensure that the chosen subwoofer complements the custom-fit box for optimal performance. Before making a selection, consult the box's specifications and guidelines provided by the manufacturer or retailer. This information will help you choose a compatible subwoofer that maximizes the box's potential, resulting in excellent bass output and audio quality.
    Custom-fit subwoofer boxes offer several advantages over generic, universal boxes: Precise Fit: Custom-fit boxes are precisely designed to match your vehicle's dimensions, ensuring a seamless and unobtrusive installation without the need for extensive modifications or wasted space. Enhanced Audio Quality: These boxes are engineered for optimal bass response, providing better sound quality and bass performance compared to generic enclosures.

Simplified Installation: Custom-fit boxes come with specific mounting hardware and instructions, making installation more accessible, even for DIY enthusiasts. Ultimately, custom-fit subwoofer boxes offer a superior solution for those seeking the best possible bass performance and aesthetics in their vehicle audio systems.
