    FAQ Frequently asked questions in Car Speakers


    There are two main types of car speakers: component speakers and coaxial speakers. Component speakers consist of separate tweeters, midranges, and woofers, which can be installed in different locations in your car for the best sound quality. Coaxial speakers combine all three speakers into one unit, which is typically mounted in the door panels.
    The most common mistakes people make when installing car speakers include:
    1. Not using the correct speaker adapters: If your car speakers do not fit the factory mounting locations, you will need to use speaker adapters.
    2. Not connecting the speaker wires correctly: The speaker wires must be connected to the speakers and the car stereo in the correct order.
    3. Not securing the speakers in place: The speakers must be secured in place to prevent them from rattling or vibrating.
    4. Not testing the speakers after installation: It is important to test the speakers after installation to make sure they are working properly.
    There are many benefits to installing car speakers, including:
    1. Improved sound quality: Car speakers can significantly improve the sound quality of your car stereo.
    2. Increased bass response: Car speakers can provide you with deeper bass, which can make your music sound more powerful.
    3. Better clarity: Car speakers can provide you with clearer sound, which can make it easier to understand lyrics and other audio content.
    4. Increased volume: Car speakers can provide you with more volume, which can be helpful if you like to listen to your music loud.
    5. Customization: Car speakers can be customized to your specific needs, such as the type of music you listen to or the size of your car.
    The cost of installing car speakers can vary depending on the type of speakers you choose, the complexity of the installation, and the location where you have the speakers installed. In general, you can expect to pay anywhere from $50 to $300 to have car speakers installed.
    There are a few factors to consider when choosing car speakers, including:
    1. The type of music you listen to: If you listen to a lot of bass-heavy music, you will need speakers with good bass response. If you listen to a lot of classical music, you will need speakers with good clarity.
    2. The size of your car: If you have a small car, you will need smaller speakers. If you have a large car, you can get away with larger speakers.
    3. Your budget: Car speakers can range in price from a few dollars to a few hundred dollars. It is important to set a budget before you start shopping.
    4. The installation process: If you are not comfortable installing car speakers yourself, you may want to hire a professional.

    All About

    Car Speakers

    Upgrading your car speakers is a tried and true method to improve your sound system. A set of aftermarket speakers is able to handle a wider range of frequencies, giving the lower notes greater depth and making the higher notes sound more defined. 

    Aftermarket products are built with more durable and temperature resistant materials than the OEM (originally equipment manufacturer). For example, most auto speakers include a rubber or foam surround for enhanced durability. 

    Sonic Electronix’s selection includes various sizes of full-range 2-way, 3-way and  component speakers.

    The most important figure when gauging a speaker's quality is sensitivity rating. A sensitivity or efficiency 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 given a set amount of input power. An efficient speaker helps you maximize your available power. 

    Selecting the Proper Speaker for Your Application

    In order to select the proper set of speakers for your sound system, look at the RMS (root mean square) power-handling rating. The RMS power is the amount of power the speaker requires to operate safely. It also refers to the amount of power a speaker can handle on a continuous basis. Sonic Electronix recommends giving speakers 75 - 90% of its recommended RMS rating to help prevent blowing your speakers.

    Full-range car speakers – which contain all elements in one for lows, mids and highs feature a woofer and tweeter both molded into the speaker. Some include midrange drivers. 

    In contrast, component systems feature separate woofers and tweeters. This allows you to mount the tweeters in an optimal location for generating a more realistic sound. They also have midranges and external crossovers, which send separate frequencies to the woofer and the tweeter for a more efficient reproduction.

    Whether you're a car audio novice or the biggest audiophile on the block, you should be able to find a pair of speakers from our wide selection that will help you build the system of your dreams.
