Price Range
Speaker Location
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.
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.
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.
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.
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 6.5" Component Speakers

    6.5" Component Speakers Frequently Asked Questions (FAQ)
    6.5" component speakers are a type of car audio speaker system that separates the audio drivers (woofer and tweeter) into individual components. Unlike regular coaxial speakers, where the drivers are mounted together in one unit, component speakers provide better sound quality and more precise imaging. The woofer is typically installed in the door panel, while the separate tweeter can be mounted in a location that optimizes high-frequency performance. This design allows for improved sound staging and a more immersive listening experience.
    The main advantage of 6.5" component speakers is their ability to produce clearer and more detailed sound compared to coaxial speakers. By separating the woofer and tweeter, each driver can focus on its specific frequency range, resulting in better sound separation and reduced distortion. The result is enhanced clarity and imaging, making it easier to distinguish instruments and vocals within the music. Additionally, component speakers are often made with higher-quality materials, which can contribute to improved durability and overall audio performance.
    Most vehicles can accommodate 6.5" component speakers, but compatibility may vary depending on the make and model of your car. Before purchasing component speakers, it's crucial to check the available space in your vehicle's door panels or dashboard to ensure a proper fit. You may need mounting adapters or brackets to install the separate tweeters in a suitable location. If you are uncertain about compatibility, it's best to consult with a car audio specialist or use an online fitment tool to find speakers that are compatible with your specific car model.
    The installation of 6.5" component speakers can be more involved than that of coaxial speakers, especially if separate tweeters need custom mounting. While some experienced car audio enthusiasts may be comfortable with a DIY installation, others may prefer professional installation services. Proper installation is crucial for optimal sound performance and to prevent any damage to your vehicle's interior. Professional installers have the expertise and tools to ensure a secure fit and proper wiring, giving you peace of mind and saving time and effort.
    The power handling and sensitivity of 6.5" component speakers can vary depending on the brand and model. Power handling refers to the maximum amount of power a speaker can handle without getting damaged. It is usually expressed in watts (W) and comes in two measurements: RMS (continuous power) and peak power (maximum power for short bursts). Sensitivity, on the other hand, measures how efficiently a speaker converts power into sound. Higher sensitivity ratings (measured in decibels or dB) mean the speaker requires less power to produce the same volume as a lower sensitivity speaker. When selecting 6.5" component speakers, consider matching their power handling capabilities with your car audio system to ensure proper performance and avoid overdriving the speakers.
