Listening to your favorite music with your stock speakers can be a pain. There is no clear separation of the frequencies, the music may sound distorted, and the vocals often sound muffled. You may also just crave the fuller sound that can be achieved by installing more speakers in your car. 

You can step up your car audio experience by replacing your factory speakers with a new set of 6.5 speakers. Most standard car speakers are between 6 and 6.5 inches in diameter. That’s very convenient because you won’t have to make a lot of modifications, if any, when installing new aftermarket speakers. We’ve put together a buying guide to help you choose between some of the best car speakers on the market.

The Best 6.5 Speakers

The Pioneer TS-A series is a three-way speaker system that will appeal to the taste of any music lover. It plays music loud and clear, and the manufacturer didn’t cut corners when making these speakers good-looking. Each speaker is made with a lightweight yet sturdy elastic polymer that enhances sound distribution and reproduction. A multilayer mica matrix cone design optimizes the unit’s frequency response, and you can expect to receive a well-balanced sound across all frequency ranges.

The speaker has an integrated tweeter to improve mid and high frequencies. It also minimizes distortion at higher volumes. Moreover, they can run cool during longer play times, thanks to the heat-resistant voice coil wire that dissipates heat. It may not have the best bass response, but that can be solved by adding a compatible subwoofer to the speaker setup. The downside to these speakers is that you have to buy mounting hardware separately.

Best 6.5 Speakers Buying Guide & FAQ

To further help you in your quest for the best 6.5-inch speakers, we have created a simple buying guide. It’s a breakdown of everything you need to know before you buy. We’ve also answered a few questions that you may have.

Why You Need 6.5 Speakers

Upgrading to 6.5 speakers can make a significant difference in your car’s audio system. Some of the benefits include:

  • Better sound quality than your factory speakers.
  • Appealing designs that complement your vehicle’s interior.
  • A compact design that can fit in the door and dashboard of most vehicles.
  • They are compatible with most factory and aftermarket head units for playing audio or video files.
  • A more affordable car audio upgrade than buying larger speakers.
  • They come with other components like tweeters, midrange, and crossovers to produce a fuller sound.
  • Can be easily installed from the comfort of your garage.

Types of 6.5 Speakers

There are two main types of 6.5 speakers:

  • Component Speakers 

Component speakers have physically separated drivers to optimize sound quality. They typically comprise of mountable tweeters, independent mid-range speakers paired with crossovers, and a separate woofer cone for the low frequencies (bass). The drivers can be mounted on different parts of your car. Component speakers excel at producing well-balanced and detailed sound across all frequencies.

  • Full Range (Coaxial Speakers)

Coaxial speakers have all the drivers built into one unit. The design consists of a woofer with a tweeter attached to the top of the cone. Most full-range speakers have a crossover built into the tweeter. They can produce sound across all frequencies, but aren’t that great at producing detailed and clean sounds. That’s mainly because the drivers are too close together, which results in distortion or interruption of frequencies.

What to Look for When Buying 6.5 Speakers

There are a few things to consider before settling on a 6.5 speaker. Be on the lookout for the following features:

  • Power Handling Rating 

6.5 speakers come with different power ratings depending on the manufacturing design. Each speaker has a maximum power rating and a root mean square (RMS), or continuous power rating. If you intend to power the speakers with your factory stereo, you should consider a unit with a low power rating to prevent blowouts. High-powered speakers are usually powered by an external amplifier. 

  • Sensitivity 

In a speaker system, some of the power is converted to sound, and the rest is mostly converted to heat in the magnet assembly and voice coils. The sensitivity rating of a speaker determines how well it can convert the power input into sound output. It’s given as the measure of watts produced at a distance of one meter. The resulting figure is expressed in dB (decibels). A car speaker rated at 90 dB is efficient and loud enough for a contained space. 

  • Material 

The construction of the speaker determines the quality of sound produced and how long it will last. The best material for making the woofer cone is polypropylene; it’s thin yet stiff enough to withstand constant vibration. It’s typically reinforced with a resilient material such as a metal thread. Tweeters, however, are best made from a soft material such as silk or ceramic for the smooth flow of high frequencies. The best speaker surround material is rubber since it’s more flexible than foam and cloth surrounds. 

  • Mounting Depth 

Most 6.5-inch speakers have a basket design, but the mounting depth varies depending on the  woofer cone design and the size of the magnet assembly. Ensure that the speaker can fit in your door panel, dashboard, or any other speaker enclosure in your vehicle. Measure the depth of your enclosure and get a compatible speaker. Alternatively, you can buy OEM replacement speakers for your vehicle model for a guaranteed fit. 

  • Frequency Response 

The frequency response, or range, is something worth considering, especially if you plan to install only one pair of speakers. It should cut across all frequencies to deliver a richer and fuller sound than your factory speakers. Component speakers have the best frequency response. However, if you have limited space, you can get coaxial speakers with a high frequency range of about 20 to 25,000 hertz. 

  • Weather Resistance 

The speakers will be exposed to extreme weather conditions and it’s good to know that they can stand it. If the speakers will be on your door, you will obviously have to open that door in the rain, and your speakers will be exposed to rainwater. If the speakers are on the dashboard, intense sun rays may damage it. Be sure to get waterproof speakers with a rubber surround that can withstand heat. 

Tips for Buying and Using 6.5 Speakers

Here are a few tips on how you can buy the best speakers and get the most from them:

  • Measure both your old speakers and the mounting hole to make sure that 6.5-inch speakers will be a good fit.
  • Prioritize speakers with a low impedance; they have less resistance to the voltage and current in your car’s electrical system.
  • If you don’t want to remove your factory speakers, you should install the new speakers at the door panel where there’s more space.
  • Buy speakers from recognized brands to get the best quality.
  • Consider upgrading your stereo or head unit to get better sound quality.
  • Play high-quality, uncompressed digital music in your car to get cleaner sounds.
  • Install sound-dampening materials at your door panel to block out road noise.

Best 6.5 Speakers FAQ:

Q: Do I need an external amplifier for my aftermarket speakers?

A: It depends on the speaker’s power rating. A low-power speaker can be powered by your stereo speaker, and you don’t have to buy an amplifier in that case. Only buy an amplifier if there’s a risk of underpowering the speakers with your head unit.

Q: Do I need to replace the wiring?

A: It’s not necessary if the original wires are in good condition and compatible with your new speakers. However, if you plan to add an amplifier that has a higher RMS than your stereo, then you should replace the entire wiring for your car audio system. 

Q: Will the new speakers improve the radio reception? 

A: The speakers have minimal impact on the quality of your radio reception. FM signals are largely affected by the interferences surrounding your driving conditions. They are also affected by poor weather. You may notice that the signal fluctuates between strong and weak throughout your drive.

Q: Do car speakers drain car battery?

A: If the speakers are installed correctly and you only use them when the engine is on, they won’t drain your battery. However, if you upgrade to a high-end aftermarket sound system with a powerful stereo and speakers that can be heard a couple of blocks away, that may strain your battery. 

Our Top Pick 

The Pioneer TS-A Series 6.5” Car Speakers stand out as the best 6.5-inch car speakers mainly because they promote enhanced sound quality from your head unit. This system promises improved frequency response, better sensitivity, and high power handling capability in comparison to the other models.
