RMS Power Handling
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 powering your speakers or subwoofer with 80%-120% of its recommended RMS rating. The RMS power handling specification is typically rated per speaker unless otherwise noted.
Peak Power Handling
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. The Peak power handling specification is typically rated per speaker unless otherwise noted.
Series
Many brands group their products into series or lines of products to help customers know the level of quality (good, better, best for example). You can filter by series and the brand using our guided browsing.
Subwoofer Size
Refers to the diameter of the subwoofer, measured in inches.
Shallow Mount Installation
This means that the subwoofer/speaker is designed to be installed in areas that do not have a lot of space. Shallow mount subwoofers are typically found under a seat or behind the seat in some trucks.

Shallow mount speakers will typically have a mounting depth of 2" or less, while shallow mount subwoofers will typically have a mounting depth of 3" or less.
Top-Mount Depth (Mounting Depth)
The depth when installed on top of the mounting surface. Measured from the bottom of the speaker's magnet to the bottom of the mounting holes on the rim of the speaker.
Voice Coil(s)
Dual voice coil subs have more wiring flexibility than single voice coils subs; however, single voice coil subwoofers provide easier hookup options for wiring multiple subwoofers in parallel or series. You may also run a dual voice coil (DVC) sub in parallel, series, or combination. A quad voice coil has four voice coils and is equal to two dual voice coil subwoofers as far as wiring goes.
Impedance (Per Voice Coil)
The load value (in ohms) that the speakers present to the amplifier per voice coil - the amount of resistance to the current flow. This is a key specification as subs wired in parallel or low impedances can create problems with your amplifier and potentially void all warranties. We encourage you to ask our support department prior to purchase if you do not understand which impedance level will suit your application best.
Subwoofer Design
This is the design of the subwoofer or the opening of the subwoofer enclosure. Each design has it's own benefits, whether it is a square, circle, or oval.

Round/Circle: This is the typical and common subwoofer design. They have a round cone and are a circle in design.

Square: These woofers are able to achieve a greater cone area in a smaller space. Because of the greater surface area, some square subwoofers will be louder than a round subwoofer of the same size.

Minimum Sealed Box Volume
This value indicates the minimum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Maximum Sealed Box Volume
This value indicates the maximum sealed box volume that the manufacturer recommends for the subwoofer. The volume is typically displayed in cubic feet.
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
  Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
Main Cone Color
This is the color of the speaker's or subwoofer's cone.
Recommended Enclosure Type
This is the recommended type of enclosure that the subwoofer should be installed into. Some subwoofers are specially designed for particular enclosures.

Sealed: These enclosures completely enclose the air inside the box. These boxes produce a tight bass.

Ported/Vented: These enclosures have a slot of air to escape from the box. The result is a sound that has more "boom".

Bandpass: These are a combination of both sealed and ported enclosures. They can be very efficient, but require tuning for the best response.

Xmax (millimeters)
Typically measured in millimeters, the Xmax value is the measure of a speaker cone's maximum excursion in one direction while maintaining a linear behavior.

    FAQ Frequently asked questions in 15" Car Subwoofers

    15" Car Subwoofers Frequently Asked Questions (FAQ)
    Yes, 15"" car subwoofers are suitable for all types of music, but their performance may vary depending on the genre and your listening preferences. These large subwoofers are designed to deliver deep and powerful bass, making them ideal for genres like hip-hop, rap, and electronic music that heavily rely on low-frequency sounds. However, their ability to handle low frequencies also allows them to enhance the bass impact in other music genres, such as rock and metal. If you enjoy music with prominent bass lines or prefer a more immersive audio experience, a 15"" subwoofer can be a great addition to your car audio system. Just make sure to pair it with an appropriate amplifier and enclosure to optimize its performance and prevent overpowering other speakers in your system.
    Before purchasing a 15"" car subwoofer, it's essential to ensure that it will fit in your vehicle's available space. These subwoofers are quite large and typically require a significant amount of trunk or cargo space. It's essential to measure the available space and consider the dimensions of the subwoofer and the enclosure you plan to use. If your vehicle has limited space, you may need to explore alternative options, such as using a smaller subwoofer or a custom-fabricated enclosure. Some vehicles may also have specific subwoofer enclosures designed to fit 15"" subwoofers without sacrificing too much space. Ensuring a proper fit is crucial to avoid any potential installation issues and to maintain the practicality of your vehicle's interior.
    The type of enclosure that is best for a 15"" car subwoofer depends on your desired bass response and the available space in your vehicle. The two common types of enclosures are sealed and ported (vented) enclosures. A sealed enclosure provides accurate and tight bass, making it suitable for music genres that demand precision, such as rock and jazz. On the other hand, a ported enclosure enhances low-end output, delivering a more resonant and boomy bass that complements genres like hip-hop and electronic music. However, ported enclosures require more space compared to sealed enclosures. If you have enough space in your vehicle's trunk or cargo area, a ported enclosure can provide a more powerful and impactful bass experience. Ultimately, the best enclosure type for your 15"" car subwoofer will depend on your musical preferences and the available space in your vehicle.
    The power requirements for a 15"" car subwoofer depend on its power handling capabilities and the desired bass output. It's essential to match the subwoofer's power handling rating with an amplifier that can deliver the appropriate amount of power. For example, if the subwoofer has a power handling rating of 500 watts RMS, the amplifier should ideally provide around 500 watts RMS at the same impedance to avoid overpowering or underpowering the subwoofer. Underpowering can lead to distorted sound and possible damage to the subwoofer, while overpowering can cause overheating and potential failure. Consider the subwoofer's sensitivity rating as well; a higher sensitivity means the subwoofer can produce more sound with less power. By ensuring proper power matching, you can optimize the subwoofer's performance and enjoy clean, powerful bass in your car audio system.
    Yes, you can install a 15"" car subwoofer in a factory audio system, but it may require additional components and modifications to achieve the best performance. Most factory audio systems lack the low-frequency output needed to produce deep and impactful bass, which is where a 15"" subwoofer excels. To integrate the subwoofer with a factory system, you'll need an amplifier that can provide sufficient power to the subwoofer. Additionally, you may need a line output converter (LOC) to connect the amplifier to the factory head unit. It's essential to adjust the amplifier settings and tune the audio system properly to ensure the subwoofer complements the factory speakers without overpowering them. Professional installation is recommended to ensure a seamless integration and to prevent any potential issues with the factory system. When installed correctly, a 15"" car subwoofer can transform your factory audio system into a powerful and immersive audio experience with deep, impactful bass.
