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.
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" Speakers

    6.5" Speakers Frequently Asked Questions (FAQ)
    6.5" speakers are one of the most popular speaker sizes used in car audio systems. The primary difference between 6.5" speakers and other sizes, such as 6x9 or 5.25"", is the cone diameter. The 6.5" size strikes a balance between larger speakers, which may provide more bass but can be challenging to install in certain vehicles, and smaller speakers, which may lack low-end frequencies. The 6.5" size is versatile and can fit in most standard speaker locations, making them a popular choice for car owners looking to upgrade their audio system without extensive modifications.
    6.5" speakers offer several advantages that make them an attractive choice for car audio upgrades. Firstly, they generally provide a better sound quality compared to stock factory speakers, enhancing the overall listening experience. They offer a more extended frequency range, allowing for clearer highs and more defined lows. Additionally, 6.5" speakers often come with improved materials and design, resulting in better durability and longer-lasting performance. They are also relatively easy to install, making them a practical choice for DIY enthusiasts.
    To determine if 6.5" speakers are compatible with your car, you need to check the speaker size of your vehicle's factory speakers. You can do this by measuring the diameter of the current speakers or consulting your car's user manual for the specifications. Alternatively, you can use an online car speaker fitment tool or contact the manufacturer to confirm the compatibility. If your car's stock speakers are also 6.5"", it's a straightforward drop-in replacement. If they are a different size, you may need mounting adapters or brackets to fit the new 6.5" speakers.
    Yes, 6.5" speakers are versatile and well-suited for various music genres. Their balanced sound reproduction allows them to handle both high and low frequencies effectively. Whether you enjoy bass-heavy hip-hop tracks, the intricate instrumentals of classical music, or the crisp vocals of pop songs, 6.5" speakers can deliver a pleasing audio experience. However, the overall sound quality also depends on the speaker's construction, materials used, and power handling capabilities. It's essential to choose speakers that match your musical preferences and offer the desired audio characteristics.
    The installation process of 6.5" speakers will vary depending on your car's make and model. However, the general steps involve removing the door panels or speaker grilles, disconnecting the factory speakers, and connecting the new 6.5" speakers using the provided wiring harness or adapters. It's crucial to follow the manufacturer's instructions and use the correct tools to avoid damaging your car's interior or the speakers themselves. If you are not confident in your DIY skills, it's recommended to seek professional installation services to ensure a proper and secure fit.
