Product Fitment Type
Speaker Size
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.
Design
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.
Total RMS Per Pair/Set
Total PEAK Per Pair/Set
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".
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.
Tweeter Design
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.
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.

    FAQ Frequently asked questions in Custom Car Speaker Kits for Specific Vehicles

    Custom Car Speaker Kits Frequently Asked Questions (FAQ)
    Custom car speaker kits are bundles of components designed to upgrade or replace the speakers in your vehicle's audio system. These kits include speakers, mounting brackets, adapters, and wiring harnesses tailored to fit your car's specific make and model. They allow you to enhance your car's audio quality by installing higher-quality speakers that match the factory locations and size requirements.
    Custom car speaker kits work by providing you with the necessary components to replace or upgrade your car's existing speakers. The included mounting brackets and adapters ensure a proper fit in the factory speaker locations, eliminating the need for extensive modifications. Wiring harnesses and connectors simplify the installation process, enabling you to connect the new speakers to your car's audio system without cutting or splicing wires. Once installed, the new speakers improve audio clarity, bass response, and overall sound quality for a more enjoyable in-car listening experience.
    Using custom car speaker kits offers multiple advantages. These kits provide a convenient solution for upgrading your car's audio system without the need for specialized tools or expertise. They ensure a proper fit in factory speaker locations, preventing the need for modifications that could damage your car's interior. Upgraded speakers deliver enhanced sound quality, with improved clarity and depth, allowing you to enjoy your favorite music with greater detail and realism. Moreover, custom speaker kits often come with all the necessary components, making the installation process straightforward and efficient.
    To choose the right custom car speaker kit, you'll need to consider factors such as your vehicle's make, model, and year, as well as your audio preferences. Look for kits specifically designed for your car's speaker locations and size requirements. Consider the type of speakers you want—coaxial or component—and their power handling capabilities. Reading user reviews, consulting online resources, or seeking advice from car audio professionals can help you find the right kit that matches your vehicle and audio preferences.
    Installing a custom car speaker kit is often feasible for individuals with basic automotive DIY skills, especially if the kit comes with detailed instructions and the necessary components. However, if you're not comfortable with car electronics or if your vehicle's wiring and speaker locations are more complex, seeking help from a professional car audio installer is recommended. Professionals can ensure proper installation, wiring connections, and speaker placement for optimal sound quality. This ensures that your custom car speaker upgrade delivers the best audio experience while preserving your vehicle's interior integrity.
