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.
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.

    FAQ Frequently asked questions in Discontinued All Car Subwoofers with Boxes

    Car Subwoofers with Boxes Frequently Asked Questions (FAQ)
    Car subwoofers with boxes, often referred to as enclosed subwoofer systems, consist of a subwoofer driver and a specially designed enclosure or box. These systems are engineered to provide optimal bass performance and convenience. The enclosure's design enhances the subwoofer's output, producing deeper, more accurate bass notes compared to a free-air installation. Car subwoofers with boxes are a popular choice for anyone seeking powerful, well-defined bass without the need for extensive custom fabrication. They're designed to fit seamlessly in your vehicle, making installation easier and more efficient.
    There are several types of enclosures for car subwoofers with boxes, each offering unique characteristics: Sealed Enclosures: These enclosures provide precise and tight bass response, ideal for music enthusiasts who prioritize accuracy and well-controlled bass. Ported (Vented) Enclosures: Ported enclosures are designed for increased efficiency and louder bass output. They are suitable for those who want a more pronounced and impactful bass experience. Bandpass Enclosures: Bandpass enclosures are highly specialized and designed for extreme efficiency in a specific frequency range. They are less versatile but can deliver tremendous output within their limited range. The choice of enclosure type depends on your musical preferences, available space, and desired bass characteristics.
    To ensure compatibility with your vehicle, you'll need to consider several factors: Size: Measure the available space in your vehicle, particularly where you plan to install the subwoofer box. Ensure the dimensions of the box will fit without obstructing other components or cargo space. Power Handling: Match the subwoofer's power handling capabilities with your amplifier's output. Ensure that your amplifier can deliver an appropriate amount of power to the subwoofer for optimal performance. Enclosure Type: Choose an enclosure type that suits your musical preferences and available space. Sealed enclosures are versatile and work well in most applications, while ported enclosures provide more output but may require more space. Impedance: Verify that the subwoofer's impedance (measured in ohms) matches your amplifier's minimum impedance rating to avoid compatibility issues. By considering these factors, you can select a car subwoofer with a box that fits both your vehicle and your audio system.
    The installation of a car subwoofer with a box can be a DIY project if you have some technical skills and the necessary tools. However, it may require professional installation in certain cases. Factors that influence this decision include your vehicle's make and model, the complexity of the audio system, and your familiarity with car electronics. If you're confident in your abilities and have access to clear instructions and wiring diagrams, you can attempt a DIY installation. However, complex systems, such as those requiring custom enclosures or extensive wiring modifications, may be best left to professional installers. A professional can ensure that the subwoofer system is correctly integrated with your vehicle's audio system, minimizing the risk of damage or incorrect installation.
    To maximize the performance of your car subwoofer with a box, consider the following tips: Proper Placement: Carefully choose the location for the subwoofer box within your vehicle. Experiment with placement to find the spot that delivers the best bass response. Amplification: Use a dedicated subwoofer amplifier to provide sufficient power to the subwoofer. Make sure the amplifier's settings are appropriately tuned for the subwoofer's specifications. Sound Deadening: Reduce vibrations and rattling within your vehicle by applying sound deadening material to doors, panels, and other resonance-prone areas. Crossover Settings: Set the crossover frequency on your amplifier or head unit to match the subwoofer's recommended range, preventing it from trying to reproduce frequencies it can't handle. Phase Alignment: Ensure the phase of the subwoofer is properly aligned with your vehicle's main speakers for seamless integration and better bass response. By following these guidelines and fine-tuning your system, you can enjoy the full potential of your car subwoofer with a box, delivering powerful and accurate bass for your listening pleasure.
