Beginner’s Guide to 6.5 Speakers

What Are 6.5 Speakers?

6.5-inch car speakers are not always the best component 6.5 speakers to use in a car, but they tend to be reasonably priced. Usually, top 6.5 component speakers are an aftermarket stereo upgrade that car owners can install to enhance their car’s sound system for a decent price. Stock speakers are often made of common materials and with a wide variety of sizes available. Plus, this means great speakers that will go with your headrest DVD player.

Factory-model speakers installed in cars can often produce lackluster results, as they’re not always the most durable speakers, even if you grab the strongest 6.5 speakers for bass. For a music lover who appreciates crisp sound, investing in aftermarket audio speakers is a good way to go. For serious audio enthusiasts who love quality speakers made with durable materials, this can be frustrating. Music and even general audio output can sound muddled and lack depth or clarity when using factory car speakers.

To help, many manufacturers are releasing car audio systems that feature extra power to drive the audio performance and give rubber sound a more significant presence in the output.

Rather than undergoing an expensive upgrade from standard car speakers, 6.5-inch car speakers offer an affordable solution that, in many cases, can be easily independently installed — even by relative novices. Additionally, these speakers are typically small, so they don’t overpower your car or require modifications and attachments.

6.5 Speakers vs. Other Car Speakers

A wide array of car speaker options on the market provide excellent sound. But 6.5-inch speakers tend to be one of the more popular options given their affordability, ease of installation, and consistent sound quality with crisp highs. Some models, like the Alpine R-series, also have a decent frequency response. They’ve considered a versatile option with wider automobile compatibility thanks to its smaller size.

However, depending on the car owner, and how important sound quality is to them, even the best 6.5 bass speakers may not be sufficient. In that case, 8-inch bass speakers offer a better sound experience with decent volume, and smooth highs, and most are at a reasonable price. While 6.5 car speakers are fairly universal, they’re not without drawbacks. The biggest issue you’ll find with this type of speaker is that it can struggle to provide consistent quality sound when listening to bass-heavy music. Basically, with a lack of watts per speaker, they’ll be unable to produce the full-range sound that audiophiles love.

Although this might not be an issue for someone listening to a genre such as classical music, anyone who prefers to listen to genres such as house music or even hip hop may find that 6.5-inch speakers are lacking. In this case, they might find themselves wanting a speaker with a wide audible range and more detailed sound.

How 6.5 Speakers Work

All speakers work by relying on a cone that has an electromagnetic coil that creates a magnetic field when exposed to a current. As the current moves, the field can attract or repel the electromagnet, which causes the speaker cone to move, creating audio waves. With 6.5 car speakers, there are two options to choose from — coaxial and component.

Coaxial car speakers (also known as full-range) are ideal for anyone working on a budget or wanting a quick and simple install. They feature a built-in tweeter and rely on subwoofers to support low to mid frequencies. Meanwhile, highs are controlled by the speaker. Coaxial speakers can be ideal if you want to replace the speakers in your car door, given their compact size and all-in-one design.

Component speakers are considered a premium 6.5 option. Unlike coaxials, they support a full sound system with a subwoofer, tweeter, super-tweeter, and mid-range speakers. And as a result, they support ultra-high and ultra-low frequencies. Because of this, component speakers are more expensive and will usually require a bit more effort to install since you’ll need to work with multiple individual parts.

But beyond ease of installation and cost, a pair of speakers needs to be compatible with your car. Typically, this factor revolves around power consumption and is referred to by the root mean square (RMS) and peak power ratings. The RMS power represents the continuous power rating for a speaker — meaning how much power the speaker draws when it’s in use. Meanwhile, peak power refers to the maximum power a speaker can handle in short periods without damaging the components. Both figures are usually listed as watts of power. The speaker wire is used to connect the woofer cone to an amplifier that will provide the power necessary to recreate a realistic sound stage.

The RMS and peak power ratings need to be compared against your car’s amp to determine compatibility. Keep in mind that RMS is more important, as this is the consistent power usage figure. But most car experts would agree that it’s always better to pick a speaker with a lower RMS or peak power rating than your car’s radio to avoid experiencing underpowered speakers struggling to perform properly.

However, there’s a caveat. Complete audio system reinstalls that also replace the radio with high-quality materials can be paired with speakers featuring higher RMS or peak power ratings. But of the two figures, the watts of peak power rating tend to be less important.

Why You Should Buy 6.5 Speakers

Some people are serious about their listening experience, which can also extend to time spent in the car. If you have a compact car and want crisp, quality sound, 6.5-inch car speakers may be just what you’re looking for. But this doesn’t necessarily mean that everyone should run right out and buy them.

Are 6.5 Speakers Worth Having?

  • You Dislike the Factory-installed Speakers: In most cases, unless you purchased a top-of-the-line car, most factory-issued speakers aren’t competitive. So even if you’re not a crazy audiophile, your car’s speakers might lack audio output quality.
  • You’re Ready to Upgrade Your Car’s Radio Deck: If you’re thinking about updating your car’s deck, it’s also worth considering a speaker upgrade.
  • You’re an Audiophile: Especially for people who feel like music is the soundtrack to their life, there’s nothing more frustrating than listening to audio through speakers with sub-par quality. Upgrading to better speakers is a no-brainer.

Why 6.5 Speakers May Not Be for You

  • You Don’t Own a Car: Unsurprisingly, you do not need to buy a set of 6.5 car speakers if you don’t own a car. If you’re more into motorcycles and want some good speakers, you can look into the best Bluetooth motorcycle speakers on the market today. Or, instead, you might be on the hunt for the best smart speaker.
  • Your Car Has a Premium Sound System: As mentioned above, top-of-the-line cars (think luxury models) usually have powerful sound systems. If you own a luxury car, you might even have a Bose system which is considered top-of-the-line. For this car owner, swapping out the sound system might be unnecessary.
  • You’re Not Comfortable with Aftermarket Car Speakers: For anyone concerned about voiding their car warranty, or performing an install that could potentially damage their car, it’s understandable that a DIY project like a sound system install might be intimidating or unappealing.

How Long Will 6.5 Speakers Last?

Most car speakers — regardless of speaker size — are designed to last several years before they need to be replaced. This can range from as little as five years to much longer than the life of the car. But as with anything, your experience will vary based on user behavior and speaker compatibility. And while it won’t really help with sound too much, you can make sure your vehicle looks as nice as it sounds with one of these great soft tops for your Jeep.

As we mentioned earlier, regardless of the type of speaker you select, you need to match the speaker’s RMS to your car’s amp. Picking a speaker with an RMS that’s higher than your car can support means you’ll experience poor performance. In that respect, your speakers will last longer, but it’ll be irrelevant since the sound quality isn’t that great. In contrast, picking an RMS that’s lower than your car’s amp can give you consistent performance.

On the other hand, if you’re the type who blares music at loud volumes, you’re going to end up damaging your speakers and significantly shortening their lifespan. Also, keep in mind that other factors, such as speaker quality, materials used, and even installation location, can also impact how long your speakers last. For example, door installations tend to be most susceptible to water damage, which will shorten functionality over time.

How to Choose 6.5 Speakers

Hands down, your biggest factor in picking the right speakers is selecting a set with an RMS compatible with your amplifier. However, other considerations, such as coaxial versus component car speakers, and even materials, can all impact your experience.

Best 6.5 Speakers Factors to Consider

1. Do you prefer component or coaxial speakers?

As we mentioned earlier, 6.5 car speakers are divided into two categories — component and coaxial. Component speakers are more expensive and composed of separate woofers, tweeters, and external crossovers. While these can take more time to install, they usually offer better sound output and quality.

Conversely, coaxial speakers incorporate mid-range woofers and tweeters. They’re often referred to as a full-range speaker and rely on an integrated crossover to help separate high and low frequencies. Along with being cheaper, coaxial speakers are usually considered easier to install and ideal for replacing door speakers.

2. What are the power ratings?

Keep in mind that speaker power ratings are listed in terms of RMS and peak power. Of the two, RMS is the more important figure as it references the consistent power draw when the speaker is in use. For best results, be sure that your speaker’s RMS doesn’t exceed your car’s receiver or the external amplifier output. Picking speakers with an incompatible RMS can cause premature damage to the speakers.

3. What is the sensitivity rating?

Once you’ve confirmed the style and that there will be plenty of power output, you’ll need to decide on the sensitivity rating. This refers to how easily the speaker converts power into sound. Higher sensitivity ratings typically translate into better sound performance because less power is needed. Sensitivity ratings are generally listed in terms of decibels (dB). Even basic speakers can provide a sensitivity that’s around 87 to 88 decibels. But if only the best will do, look for speakers with a sensitivity rating of 90 decibels or higher.

4. Is the speaker made from quality materials?

No matter how great your speakers sound, if they’re made from cheap materials, you can’t expect to get more than a few years of use before they need to be replaced. For example, a polypropylene cone will last longer than one made from paper. Along with durability, don’t forget to consider where you’ll be installing the speaker and pick accordingly.

5. Are they water-resistant?

This question is especially important if you’re replacing door speakers. You’ll want to focus on models incorporating water-resistant materials or having a water-resistance rating. For best results, prioritize speakers that have an IP64 or higher rating.
