Question Mark Icon of Question Mark
Refers to the size of the speaker measured in inches. Every vehicle has standard application sizes. Please use our vehicle fitment guide for your vehicle's specific speaker sizes if you do not know them.
Question Mark Icon of Question Mark
The number of individual drivers in a car speaker. Speakers with 2 drivers are known as a 2-way, and 3 drivers are known as a 3-way. Component systems are often referred to as "separates" because the tweeter is not attached to the midwoofer (main speaker driver) and mounts separately in a location such as a door post. Component systems typically come with an external crossover so you can easily adjust the high and low frequencies sent to both the midwoofer and the tweeter. Center channel speakers are great for those looking to have surround sound in their vehicle.
Question Mark Icon of Question Mark
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.
Question Mark Icon of Question Mark
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.
Question Mark Icon of Question Mark
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".
Question Mark Icon of Question Mark
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.

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.

Question Mark Icon of Question Mark
Designs such as cone, dome, semi-dome, balanced dome, and whizzer are most popular. Cone tweeters are simple, efficient and typically are the most reasonably priced. Dome tweeters are used in most home speakers, and provide a smoother and more accurate sound. Semi-dome design is one with a dome placed inside a cone. A Balanced dome driver is a semi-dome with equal reproduction area given the cone and dome portions of the driver. A whizzer tweeter is a separate tweeter cone driven by the voice coil of the woofer.

    All About Discontinued 4" Speakers


    4” Car Speakers

    4" car speakers, also known as 4" coaxial speakers, are designed to fit into small spaces in your vehicle, such as the doors or dashboard. Marine and power sport vehicles commonly use 4" speakers because of their durability and reliability in harsh environments. As far as factory-installed car speakers go, the maximum tweeter size is 4 inches. They can produce highs, mids, and lows, allowing for crisp vocals and a thumping bass.

    4" car speakers typically have two components: a woofer and a tweeter. The woofer produces low-frequency sounds, such as bass and drums. At the same time, the tweeter handles high-frequency sounds, like vocals and cymbals. Some 4" speakers have a built-in crossover network that divides the audio signal and sends the appropriate frequencies to the woofer and tweeter.

    Upgrade your car's sound system with these convenient and affordable 4" car speakers. Though diminutive in size, they can produce high-quality audio with crisp vocals. Sonic Electronix carries a wide variety of aftermarket 4-inch automobile speakers from industry-leading brands, including NVX, Kicker, JL Audio, JBL, Rockford-Fosgate, Alpine, Kenwood, Cerwin-Vega, and many more.

    4" Speakers Frequently Asked Questions (FAQ)
    4" speakers, also known as 4-inch speakers, are compact audio drivers designed to reproduce mid-range frequencies in car audio systems. They are a common speaker size found in various vehicles, especially in the dashboard or door panels. 4" speakers are often used as factory or OEM speakers due to their small size and ability to fit in tight spaces. These speakers play a crucial role in delivering clear vocals and mid-range frequencies, contributing to a balanced soundstage. While they may not produce deep bass like larger subwoofers, 4" speakers are essential for achieving a well-rounded and enjoyable listening experience.
    Upgrading to aftermarket 4" speakers offers several advantages over factory speakers. Aftermarket speakers typically feature higher-quality materials and construction, resulting in improved sound clarity and accuracy. The use of premium components, such as polypropylene or mica-infused cones and silk or Mylar dome tweeters, enhances the overall sound performance. Aftermarket 4" speakers can handle more power, reducing distortion at higher volumes and delivering a cleaner sound. Additionally, some aftermarket 4" speakers come with swivel or pivot tweeters, allowing you to adjust the sound direction for better sound staging. Upgrading to aftermarket speakers also allows for customization, as you can choose speakers that match your preferred sound signature. Overall, the upgrade to aftermarket 4" speakers significantly enhances the audio quality and listening pleasure in your car.
    To determine if 4" speakers are compatible with your vehicle, you'll need to check the available space for speaker installation. Measure the diameter and mounting depth of the existing speakers or speaker locations in your car's dashboard or door panels. Most 4" speakers have standardized measurements, but some vehicles may have unique speaker mounting requirements. If your car came with factory-installed 4" speakers, it's usually a straightforward replacement with aftermarket 4" speakers. However, some vehicles may have non-standard speaker sizes or mounting configurations, requiring additional adapters or modification for a proper fit. To ensure compatibility and a hassle-free installation, consider consulting a car audio professional or using an online fitment guide.
    While 4" speakers can reproduce mid-range frequencies with clarity, they are not designed to produce deep bass like larger subwoofers or woofers. Their compact size limits their ability to move a significant volume of air required for low-frequency reproduction. However, many 4" aftermarket speakers are designed with improved bass response compared to factory speakers. They use advanced engineering and materials to optimize the mid-bass performance, providing a more balanced sound. Additionally, if you seek enhanced bass, consider pairing 4" speakers with a subwoofer or a larger speaker system. The combination of 4" speakers for mid-range and high frequencies, along with a dedicated subwoofer for low frequencies, can result in a more robust and satisfying audio experience with full-range sound reproduction.
    The installation of 4" speakers can vary depending on your car's make and model, as well as your level of experience with car audio installations. If your vehicle has straightforward and accessible speaker locations for 4" speakers, you may be able to handle the installation yourself with the right tools and know-how. Many aftermarket 4" speakers come with installation instructions and mounting accessories, making the process more manageable. However, some vehicles may have more challenging installation requirements, such as custom mounting brackets or adapters. If you are unsure about the installation process or lack experience, it's advisable to seek professional installation. Car audio experts can ensure a proper and secure fit for optimal sound performance and prevent any damage to your vehicle's interior. Professional installation also provides peace of mind knowing that your new 4" speakers are set up correctly for the best audio experience.

Due to their smaller footprint, they can be easily mounted in various locations within your vehicle, making them suitable for cars with limited space for speaker placement. Additionally, their compact design allows them to integrate seamlessly into the existing audio system.

    4” speakers are also known for their excellent mid-range performance, which is crucial for reproducing vocals and instruments with exceptional clarity and detail.
