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 Discontinued 12" Car Subwoofers

    12" Car Subwoofers Frequently Asked Questions (FAQ)
    A 12’‘ car subwoofer is a specialized speaker designed to reproduce low-frequency bass sounds in a car audio system. It measures 12 inches in diameter and is one of the most popular sizes among car audio enthusiasts. The 12’‘ subwoofer offers a balanced combination of deep bass response and overall audio performance, making it suitable for a wide range of music genres. Its larger size allows it to move more air, producing powerful and impactful bass. If you enjoy music genres like hip-hop, EDM, or rock, a 12’‘ subwoofer will enhance your listening experience by adding depth and realism to the low frequencies, creating a more immersive soundstage in your vehicle.
    Before purchasing a 12’‘ car subwoofer, it's crucial to ensure that it will fit in your car's available space. The first step is to measure the area where you plan to install the subwoofer. Measure the width, height, and depth of the available space, and compare it with the dimensions of the subwoofer you intend to buy. Keep in mind that some subwoofers require enclosures, so consider the total space required for both the subwoofer and enclosure. Additionally, consider the mounting depth of the subwoofer to ensure it won't interfere with other components in your vehicle. If you're unsure about the compatibility, consult with a car audio professional who can help you find the best 12’‘ subwoofer that fits your car and audio preferences.
    Most car audio systems' built-in amplifiers are not powerful enough to properly drive a 12’‘ car subwoofer. Subwoofers typically require more power to produce deep and impactful bass. For a 12’‘ subwoofer, you will need a dedicated external amplifier that can deliver sufficient power to the subwoofer for optimal performance. The power rating of the subwoofer, measured in watts RMS, will give you an idea of the amplifier power needed. It's essential to match the subwoofer's RMS power handling with the amplifier's output to prevent underpowering or overpowering the subwoofer, both of which can affect sound quality and potentially damage the equipment. A compatible external amplifier will ensure that your 12’‘ car subwoofer delivers the best bass performance possible.
    The type of enclosure significantly impacts the performance of a 12’‘ car subwoofer. There are three main types of enclosures: sealed, ported, and bandpass. Each enclosure type has its characteristics, and the choice depends on your audio preferences and the desired bass response. A sealed enclosure provides tight and accurate bass, ideal for music genres that require precise bass reproduction. Ported enclosures deliver louder and more boomy bass, suitable for genres like hip-hop and electronic music. Bandpass enclosures offer a combination of both sealed and ported characteristics, providing the most powerful bass output. To determine the best enclosure for your 12’‘ subwoofer, consider your music preferences, available space, and desired bass response. Consulting with a car audio professional will help you select the ideal enclosure type for your specific subwoofer and vehicle.
    Installing a 12’‘ car subwoofer involves more than just connecting wires, so professional installation is often recommended. Properly installing the subwoofer, selecting the right enclosure, and tuning the audio system for the best sound quality can be challenging for those without experience in car audio installation. A professional installer has the expertise and tools to ensure that the subwoofer is mounted securely and tuned correctly to provide the desired bass performance. They can also help integrate the subwoofer into your car's interior seamlessly, giving your audio system a polished and professional look. Additionally, professional installation reduces the risk of damaging your vehicle or audio equipment during the installation process. Investing in professional installation guarantees that your 12’‘ car subwoofer performs at its best and provides an exceptional bass experience.
