Why buy new car speakers?
Are you unsure about replacing your stock speakers?
Quality aftermarket audio parts offer superior sound quality. Since vehicle manufacturers are often focused on the performance and safety features of a car, vehicle audio components are typically cast aside.
Fortunately, you can purchase sophisticated aftermarket parts that consist of high-quality sound-producing elements, including tweeters, woofers, midrange, and crossovers. These speakers are capable of working alongside your stock radio or other aftermarket stereo parts in order to create crisp highs and punchy lows.
While other audio system additions can be costly, a quality pair of 6.5 coaxial speakers are an affordable investment that can bring about noticeable improvements. What’s more, most people can install these components from the comfort of their garage or driveway
What’s the difference between coaxial and component speakers?
Coaxial speakers are full-range speakers. They combine mid-range woofers and tweeters to produce a full spectrum of sound. Most coaxial speakers feature an integrated crossover that helps separate highs and lows. The main advantage of this type of speaker is that all of the components are housed together, making them perfect for squeezing into a car door.
On the other hand, component speakers consist of separate woofers, tweeters, and crossovers. A large external crossover makes it possible to create more defined highs and lows. However, it is more difficult to install this type of speaker. Check out this informative YouTube video for a more detailed look at the differences between coaxial and component car speakers.
If you’re confident in your ability to install car audio parts and you have plenty of money to spend, you can’t go wrong with a high-quality component speaker set. If so, be sure to check out our component speaker buying guide.
How much power do I need for my new speakers?
One of the major differences between speakers is their power ratings. With that said, most manufacturers provide customers with both RMS (root mean square) and max power ratings. An RMS, or continuous power rating is what a speaker consistently uses during its performance.
Keep in mind that speakers with low RMS ratings pair well with low-powered factory-installed radios. Whereas, speakers with high RMS ratings work best with high-powered aftermarket amps. Do your best to find speakers that are compatible with your receiver or amp, as an attempt to pull too much power can damage these components. Keep in mind that it is always better to overpower rather than underpower your speakers.
Speakers also tend to be labeled with a peak power rating. This rating applies to the maximum amount of power that can be used during a short period of time. This amount of power can be safely used without causing any damage to the speakers. Of course, this number is not representative of how much power is required.
What 6.5 speakers are best for bass?
Even the best 6.5-inch speakers are going to struggle to put out a lot of bass. Deep bass doesn’t come without a good subwoofer.
6.5 speaker is not designed to produce good bass but for midranges or midbass.
A speaker’s sensitivity rating paints a picture of how easily power is converted into sound. Speaker sensitivity is a measurement of the number of watts produced at a 1-meter distance.
For example, a speaker with a sensitivity of 80 watts produces that amount of volume 1 meter away from the unit.
What materials are best materials for car stereo systems?
Speakers consist of several different parts that work together to produce high-quality sound. A speaker’s woofers are made from thin, yet stiff materials, such as polypropylene. They are often reinforced with metal thread and other resilient materials.
Meanwhile, tweeters are made from incredibly soft materials, including silks, metals, and ceramics. In addition, speakers typically feature surrounds. These parts are made from pliable materials, such as rubber and cloth.
|Tweeter||Silk, polyurethane for mellow sound. Metal, ceramics and graphite for brighter highs.|
|Woofer||Polypropylene best for bass. Woven fabrics or metal coated synthetics also be used.|
|Surround Materials||The best material is rubber. Foam and cloth surrounds are less expensive.|
Do speakers ever sport specialty features?
Audio part manufacturers are constantly adding unqiue features to help their speakers stand out. These features include pivoting tweeters, designer grills, and integrated controls. While elements like these can definitely improve a speaker, the core components should never be ignored.
Why does a speaker’s durability matter?
Car speakers are installed directly into car doors. As such, they often come in contact with rain, mud, and snow. What’s more, they are constantly at odds with vehicle vibrations. These conditions are often worse in off-road and all-terrain vehicles.
To help eliminate durability issues, manufacturers have developed water- and dust-resistant speakers. These speakers are typically marine certified or boast high a Ingress Protection (IP) rating. Keep in mind that an IP rating of 61 protects a speaker from minimal condensation, whereas an IP rating of 64 protects from water spray coming from every possible direction.
Quality 6.5 speakers serve as a major upgrade to factory-installed audio components. Whether you pair them with a stock stereo or an aftermarket amp, these impressive all-in-one speakers offer a full spectrum of impressive sound.
