How to Choose the Right One for Your Car – Buyer’s Guide
With a working audio system in your vehicle, you can listen to your favorite music. You can listen to updates on current events. You can even take a tour of the Everglades through the National Park Service.
The quality of your car’s audio system matters, and sometimes, you want an upgrade from the factory-installed system. Aftermarket 6×9 speakers are a great way for first-time audiophiles to try out speaker upgrades.
Just make sure that your new sets comply with local noise regulations. Some areas have restrictions on how loud your speakers can be.
Whether you’re looking for the best 6×9 speakers for bass or just trying to understand some basic terminologies, this buyer’s guide is a great place to start.
1. What specifications should I understand when researching?
When gauging the quality of a 6×9 speaker, pay attention to the following specifications:
- “Peak” or “Maximum” Power: the maximum amount of power a speaker can handle during a brief burst of music; measured in watts
- RMS Power: the maximum amount of power a speaker can handle on a continuous basis; measured in watts
- Impedance: the resistance of a speaker’s voice coil to the audio current supplied by the amplifier; measured in ohms
- Sensitivity: the speaker’s ability to convert power into acoustic sound; measured in decibels
All speakers require a power source from a receiver or amp.
The first two measurements of power-handling will help you determine whether the speakers will match well with your existing system.
Note the chief difference between RMS power and peak power. RMS power measures how much the speaker can handle continuously. Peak power measures how much the speaker can handle in one short burst.
For this reason, RMS power is a more useful measurement when determining speaker suitability.
Fun fact: RMS stands for “Root Mean Square,” the statistical measurement that generates RMS power measurements.
Impedance also measures the amount of power that the speakers can handle. The lower the impedance measurement, the more easily the electricity—the signal or music—flows through the speaker.
A speaker’s sensitivity measures its ability to convert that power into sound. The higher the number, the better—it indicates how much sound you’ll get at a given volume. Sensitivity is measured in decibels, usually noted as “dB.”
- RMS and peak power ratings gauge how much electricity a speaker can handle.
- Impedance measures how much the speaker will resist that power.
- Sensitivity measures how well the speaker will turn that power into sound.
You’re unlikely to find any specific measurements of sound quality, as objectively gauging sound quality presents certain complications.
2. What is a Three-Way and Two-Way Speaker?
The “driver” is the part of the speaker that produces the sound. Three-way speakers have three drivers; two-way speakers have two drivers.
In two-way speakers, one of the drivers is for high frequencies, and one is for mid to low frequencies. They usually include a tweeter and a midrange driver.
In three-way speakers, the three drivers support a set range of frequencies. This setup is easier overall for the speakers than the two-way setup. They include a tweeter, a woofer, and a midrange driver.
If you’re looking for the best possible sound, a three-way set might be your best choice. If you’re looking for better sound on a budget, a two-way set should be fine.
Three-way speakers produce better quality bass, due to the inclusion of a woofer.
3. What are “Coaxial” Speakers?
Also known as “full range” speakers, reproduce a larger range of audio frequencies from one unit. The drivers in them are combined, saving money and space.
They are usually two-way speakers, with a tweeter mounted on top of a woofer. Three-way coaxial speakers contain a woofer, a midrange, and a tweeter.
Compared to component speakers, full range or coaxial are less expensive and easier to install.
Component speakers provide better sound quality and more opportunities for customization. In a component speaker system, the woofers and the tweeters come separately with external crossovers. Because the tweeters and woofers are separated, you can mount them in ideal locations for the best sound imaging.

3. Editor’s Choice for Bass – Kicker 40CS6934
The Kicker 40CS6934 is a three-way, coaxial speaker that delivers an ultra-clean bass at high volumes. With an impressive RMS power of 150 watts and peak power of 450 watts, this set of four can handle a lot of power while filtering a delightful, car-rattling sound.
Information about car audio systems tends to confuse the novice audiophile. But now that we’ve defined a few terms and outlined some of the better speakers available, you should feel more comfortable deciding and tackling an installation.
Pay attention to the power handling measurements, the sensitivity, the impedance, and the tweeter/woofer setup. If you’re interested in heavy bass, you’ll want something with low impedance, high power handling measurements, and high sensitivity. In all cases, make sure that the ones you buy can handle the electricity they’ll receive from your car.
