Top Picks of Best 3-1/2" Speakers: Upgrade Your Car Audio

Upgrading your car’s audio system by changing the speakers can greatly improve the sound quality. But picking the best 3-1/2″ speakers can be tricky because so many options are available online and in stores. In this article, we’ll help you choose the best & right  3-1/2″ speakers for your car. Even though these speakers are small, they can still produce plenty of volume. 

Plus, they have good power handling to give you maximum sound output. They also have features like subwoofers to enhance lower frequencies and tweeters to handle high notes. But with so many models and brands out there, it can be hard to decide which ones are the best. So, let’s take a look at the top 3-1/2″ speakers available in the market.

Types of 3-1/2" Speakers

Coaxial Speakers

Coaxial speakers are a basic upgrade from factory speakers. They combine a tweeter and a woofer in one unit, sometimes with an added mid-range speaker for better sound quality. Coaxial speakers are easy to find and install.

Component Speakers

Component speakers, on the other hand, have separate parts for better sound. They typically include a tweeter, woofer, and sometimes a mid-range speaker. This separation improves sound quality but can be more expensive and take longer to install compared to coaxial speakers.

Full-Range Speakers

Basic full-range speakers have a tweeter and woofer, with the tweeter typically on top of the woofer. Some may also have an extra driver, such as a midrange or super tweeter. They’re usually easy to install and come in different price ranges.

Features to Look for When Buying 3-1/2" Speakers

When replacing your factory car speakers with 3.5-inch ones, consider a few key factors to help you choose the right ones. Although we’ve reviewed the top five options available today, each speaker is designed differently and serves different car music needs. Here’s a simple buying guide outlining the most important things to consider when shopping for replacement 3.5-inch car speakers.

1. Price

These speakers can cost anywhere from $20 to $300. There are lots of options in different price ranges. Coaxial speakers are usually cheaper, around $50, while component speakers can be more expensive. Pick speakers that have the features you want and fit your budget.

2. Sensitivity

Sensitivity is how loud a speaker can get compared to the power it uses. Higher sensitivity means louder sound with less power. Look for a speaker with at least 88 decibels (dB) for good volume without using too much power.

3. Power Handling

The power output of a speaker affects how good it sounds. Power handling capacity tells you the maximum power a speaker can handle without distortion. It’s measured in watts and can be shown as peak and RMS power. So, choose a speaker with high-power handling for better sound quality.

4. Compatibility

Make sure the 3.5-inch speakers you pick work well with your car’s audio system. They should fit in easily without needing any changes. Check things like power handling, impedance, and sensitivity to make sure they match your car stereo.

5. Size

Check the speakers’ size and shape to ensure they’ll fit properly in your car without taking up too much space or being hard to install. The right-sized speakers will sound better without any problems.

6. Impedance

The amount a speaker resists the electric current from an amplifier is measured in ohms. Lower impedance means the speaker uses more power efficiently and lets the electric signal pass through easily, resulting in better sound quality. Look for a 3.5-inch car speaker with an impedance rating of 4 to 8 ohms to avoid putting too much strain on the amplifier.

7. Frequency Response

The range of sounds a speaker can accurately make, from low bass to high treble. Most people can hear sounds between 20 Hz and 20,000 Hz. For better sound quality, make sure to get a speaker that can cover a wide range of frequencies.

8. Material & Build Quality

The stuff a speaker is made of and how well it’s put together affect how long it lasts and how good it sounds. Look for speakers made of strong materials like silk, metal, or graphite for tweeters and aluminum, polypropylene, rubber, or graphite for woofers. Make sure they’re built well to last and sound good.

9. Mounting Depth or Installation

The speakers’ depth will decide where to put them in your car – either on the dashboard or side window/door. If you’re putting them on the dashboard, you’ll need about 2.5 inches of depth. You’ll need more depth if you’re putting them on the window or door. But if they’re too deep, you might not be able to use speaker grills, or they might get in the way of the window crank.

10. Brand Reputation

People usually like buying from trusted brands because those brands are known for making good car audio. For better performance, look for speakers from brands like JBL, Pyle, Kicker, Boss, Rockford, Infinity, or Skar Audio.

11. Additional Features

Some 3.5-inch speakers come with extras like crossovers and tweeters to improve the sound. Tweeters make the music clearer and more detailed, while crossovers filter out unwanted sounds and ensure the right sounds come through. Look for speakers with these extras for better sound quality.

Speaker Care Tips for Better Sound and Longer Life

  • Dust can make your speakers sound muffled. Use a soft brush to gently remove dust from the speaker net. Avoid liquid cleaners as they might damage metal parts.
  • Regularly inspect the wiring and woofer cone for tears or damage. Repair small tears and cover exposed wires with adhesive tape to prevent further damage.
  • Direct sunlight can melt plastic parts, harm voice coils, and distort speakers’ shapes. To maintain their shape and function, keep your speakers away from direct sunlight.
  • Good airflow helps your speakers perform better and last longer. Install speakers near car cooling vents or increase the mounting hole size to prevent overheating, especially during heavy use.

Conclusion

Even though they’re small, 3.5-inch car speakers are awesome replacements for most cars. Unlike tweeters that only play high sounds, these speakers give you all the different tones. It might be a bit hard to find ones with covers, but the covers that come with your car will usually fit. So, upgrade your car with these Best 3-1/2″ Speakers.

Frequently Asked Questions

Factory speakers don’t handle car electrical power well, so they often produce low-quality sound. Aftermarket speakers, especially brand-name ones, are usually louder and better. Adding an amplifier can make them even louder and clearer.

It depends on the car model. Most 3.5-inch speakers fit in car dashboards or upper door panels, especially small cars. Some cars might need modifications or adapters to fit.

Connecting speakers to an amplifier improves audio quality, giving a clearer, crispier, and more balanced sound. High-impedance speakers need an amp, while low-impedance ones don’t require it.

If you can install them yourself, there’s no installation cost. Otherwise, professional installation can cost between $150 to $500, depending on factors like car model, speaker model, location, and expertise.

Yes, usually, these speakers have less bass because they’re small. Bass needs space to spread through the woofer, and smaller speakers have less room. Look for models that offer a good bass response.

Which size you choose ultimately depends on your preferences and the type of system you use them in. Choose 5×7 speakers if you prefer a compact and easily installable option, whereas 6×8 speakers may be the better choice for those seeking enhanced sound quality.

3-way speakers are better because they have an extra driver, which spreads frequencies evenly. This results in clearer and more detailed sound output.

However, if you want to listen to some pop or rock music, a 3-way speaker might be a better choice. Remember to test different speakers to find the best one for you.
