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.

    All About Car Speaker Packages & Bundles

    Speaker Packages & Bundles

    This speaker packages and bundles category to help you find bonus deals with extra items included to help make your installation of car speakers even easier. You can get adapter mounting brackets, speaker wire, harnesses to eliminate cutting your factory wires

    Most car manufacturers come with stock sound systems that lack power and quality. The most common way people upgrade their car stereos is by installing a new head unit.  This is the in-dash component that allows you to control everything from CDs, AM/FM radio, communication and sometimes vehicle climate control. 

    Amplifiers and subwoofers are necessary to increase the power of the audio system and maintain music fidelity. The amplifier that comes in most head units cannot power upgraded speakers. To get these features while keeping enough energy flowing to the speakers, an amplifier will be needed to ensure each component is getting enough power. Especially if you want to add an aftermarket subwoofer or any specialized speaker. 

     A set of subs increases the base output. Most people associate these with loud music that rattles the bumper – which subwoofers are more than capable of generating. Even so, subs were created to make low frequency sounds that mid-range and factory speakers can’t. You can crank up the bass for a chest thumping experience, or to bring new depth to any musical genre. 

    Replacing the main speakers with excellent tweeters provides the same boost in power and quality for high frequencies.

    Coordinating all the different components necessary to upgrade your car stereo can be tedious. This category is dedicated to packages Sonic Electronix has created to match your desired amplifier and subwoofer, subwoofer and its enclosure, head units and backup cameras, and so on. There are also premium car audio kits that come with a new stereo, subwoofer and speaker box, front speakers, amp, and all the necessary wiring.
