When it comes to quality car speakers, you don’t get much better than a pair Rockford Fosgates, and with these R14X2’s they’ve delivered a stunning 4-inch speaker that produces clean, powerful sound for a price that won’t destroy your bank account.

Featuring a high-quality vacuum polypropylene cone with rubber surround and ½” silk dome tweeter and an integrated high-pass crossover, these speakers were built for performance. They have a power range of 2-30 watts RMS (60 watts peak power), a frequency response of 100-20,000 Hz and boast a sensitivity rating of 85 dB and are capable of producing stunning sound quality.

These speakers are our choice for the best overall 4-inch car speaker.

2. Pyle PLG4.2 Car Two Way Speaker System – Best Value

Pyle PLG4.2

If you are looking for the best 4-inch speakers for the money, you really should take a look at these inexpensive Pyle Audio Gear Series speakers. They have a frequency response of 90-20,000 Hz and can handle 70 watts RMS (140 watts peak), making them no slouch in the performance department.

Sure, they are from a lesser-known brand in the car speaker market, but Pyle Audio has been making quality audio equipment since the 1960s, and in terms of pure bang for your buck these speakers are hard to beat.

Pros
  • Price
  • Good performance
Cons
  • Lesser known brand

3. Polk Audio 4-Inch Pair Coaxial Speakers – Premium Choice

Polk Audio DB401

Polk Audio has an excellent reputation for building quality speakers with great sound, and these DB401 speakers won’t disappoint.

They feature laser imaged dynamically balanced woofer cones, which have been designed to eliminate resonance and provide a smooth, clear bass, as well as silk polymer composite tweeters for detailed mid and high tones.

They have a power ranger of 4 – 45 watts RMS (135 watts peak),  a frequency response of 85 – 22,000 Hz and a sensitivity of 91 dB,  which all comes together to make these speakers an excellent match for any factory or aftermarket stereo unit. They’re also marine certified, making them an excellent choice for anybody driving an open-top or off-road vehicle that may occasionally have water entering the cab.

We like these speakers, and they were a contender for our top choice, but as you can purchase a pair of Rockford Fosgate R14X2’s for a little over half the price of these speakers, Polk Audio will just have to settle for being our premium choice.

Pros
  • Excellent build
  • Great sound
  • Marine certified
Cons
  • Price

Featuring an injection-moulded polypropylene cone, a mid-range 15/16-inch Light Weight Balanced Dome and a ⅜-inchDome Tweeter these speakers produce smooth, accurate sound with minimal distortion. A fact that isn’t surprising when you consider their specs, as they can handle 20 watts of RMS power (135 watts peak), and they have a frequency response of 45 – 30,000 Hz and a sensitivity of 90 dB.

Buyer’s Guide

When you are looking to buy a set of 4-inch speakers (or any other sized speakers for that matter), there are several things that you need to consider. These included the type of speakers that you want to install and the unique specifications and features of the various models that fit your budget.

If you don’t know what to look finding the right speaker can be a little tricky, so to help you out, here’s a quick breakdown of some of the things you should consider.

Speaker type

When it comes to choosing car speakers, there are two basic types to consider, coaxial (or full-range speakers) and component speakers.

Full-range speakers are built with the cone and tweeters within the same unit. They are by far the most popular type of speakers for people looking to replace factory fitted speakers, and this is generally because they are cheaper and a lot easier to install.

Component speakers, on the other hand, are both considerably more expensive and more challenging to install and set-up. A typical component system includes separate woofers, tweeters, and external crossovers — all of which work with one other to produce the best possible sound.

To keep things simple, all of the speakers we have suggested in our reviews are full-range speakers.

Build Quality

Build quality is more of a consideration when purchasing budget speakers.  At the lower end of the market, you are not going to be able to expect the same exacting standards as in high-end speakers. So, it’s worth taking the time to consider reviews and see what other people have had to say about the quality of the speakers you are considering buying before you part with your money.

Sensitivity and Power handling

To work effectively, your speakers need to be able to handle the power output of your stereo unit or amplifier. Power is measured in watts RMS, and this relates to the amount of power a speaker can handle before the sound quality gets distorted.

If you want to run a high powered amplifier, you need to ensure your speakers can handle the power. Otherwise, your music will sound terrible, and you will likely blow or damage your speakers.

Sensitivity refers to the amount of power that speakers need to produce sound. If you have speakers with higher sensitivity, they will need less power. They may be more suitable for low powered stereo units such as factory fitted or inexpensive aftermarket models. Whereas low sensitivity speakers require more power.


Conclusion

Hopefully, having read our reviews, you’ve now got a good idea of what you are looking for in a set of 4-inch speakers.  All of the speakers we have reviewed in this article are what you might consider being good speakers, and could be the right choice for you. However, our winners are:
