Kicker is one of the most serious contenders in the car audio industry. They offer some great sounding car speakers for an affordable price.

Their DS series speakers are a great replacement to factory-installed speakers. In addition to their low price tag and well-balanced sound output, these speakers offer a thin profile that allows them to fit in most vehicles out there.

Kicker-41DSC44 4 inch car speakers at hand are featured with 4″ polypropylene woofers supported with ribbed polyester foam surround which allow for punchy and defined bass. As for highs, these 2-way speakers use 1/2″ PEI domed tweeters which ensure you get every bit of clarity you need and bring out your music’s detail and depth with no shrillness.

Technically, these speakers can get as low as 60HZ, and as high as 20 kHz which is actually pretty good for small speakers.

These Kicker 4″ speakers can handle up to 30 watts on continuous basis which is quite relatively good for a set of speakers this size. Their high sensitivity rating coming in at 88dB allows these speakers to sound good even when they’re paired to a low-powered factory radio, so you can crank your tunes and keep ’em blasting the whole ride.

These are but a few reasons to seriously consider getting your hands on Kicker-41DSC44 4 inch car speakers.

2. Pioneer TS-A1072R

Size 4 inch
Design 3-way
Frequency range 45 – 30,000 Hz
Power Handling 
  • RMS: 20 Watts
  • Peak:150 Watts
Sensitivity 90dB
Impedance 4 ohms

This is another great 4 inch speakers set from Pioneer, which is easily one of the most recognised car stereo brands in the world.

Pioneer offers quality car audio components at great prices. Their car speakers, TS-A series speakers particularly seems to hit the sweet spot for a lot of guys due to the fact that they provide great sound quality at an affordable price.

Pioneer-TS-A1072R 4″ car speakers cones are equipped with lightweight IMPP cones which significantly reduce mid-to-low range distortion and allow for a great sound-staging. These cones are designed with long aramid fibers to provide strength and durability that powerful bass sound requires.

In terms of highs, these Pioneer 4 inch speakers are featured with 3/8″ Dome Tweeters which deliver smooth, accurate highs. And since these are 3-way speakers, you’ll find a light weight balanced dome with magnetic fluid midrange which is responsible for mids reproduction.

Pioneer-TS-A1072R 4 inch speakers feature one of the highest sensitivity rating (90dB) and can handle a decent amount of power on continuous basis (20 watts RMS). This makes these speakers compatible with most factory or aftermarket headunit.

That being said, if you’re looking for a decent and easy replacement for your worn-out factory-installed speakers without having to splurge too much money, then Pioneer-TS-A1072R would be a great buy.

3. Rockford Fosgate Punch P142

  • Mineral-filled polypropylene woofer cones
  • Butyl rubber surround
  • 3/4 inch Polyetherimide (PEI) dome tweeters
  • Vertical Attach Surround Technique (VAST™) increases cone area

Last update on 2021-02-14 / Affiliate links / Images from Amazon Product Advertising API

Size 4 inch
Design 2-way
Frequency range 100 – 22,000 Hz
Power Handling 
  • RMS: 30 Watts
  • Peak: 60 Watts
Sensitivity 86.5dB
Impedance 4 ohms

This is not any Rockford Fosgate, this is the Punch P142 which is all you need to know about these speakers. Indeed, Punch is such a remarkable series that it has managed to accumulate so much positive feedback for the company and the brand as a whole.

Unsurprisingly, this is a powerful set of speakers that is capable of handling 60 Watts at its peak and a 30 watts on continuous basis.

Combine that with their relatively high sensitivity rating of 86.5 dB and you get speakers that can make a night and day difference.

As is the case with Rockford Fosgate’s Punch Series of speakers, these 2-way speakers are designed from the groun up to breath a new life into your car stereo system allowing you to enjoy well-balanced sound and feel it too.

These speakers at hand were designed to be a high-grade replacement for factory-installed speakers. They’re featured with mineral-filled polypropylene woofers supported with butyl rubber surround that’ll stand up to hours of high-volume jams. Rockford Fosgate uses a new technique — Vertical Attach Surround Technique (VAST™) — to attach the surround to the cone that yields up to 25% more cone area, resulting in fuller sound and stronger performance.

Additionally, these speakers use 3/4″ Polyetherimide (PEI) dome tweeters which provide clear, sharp highs that can hold their own under heavy bass.

If I had to pick some criticism for the Rockford Fosgate P142 car speakers, It would be their relatively narrow frequency range. While most 4 inch car speakers we listed here can reach as low as 45 Hz, these speakers can only hit 100 Hz.

4. JBL GTO429

Size 4 inch
Design 2-way
Frequency range 75 – 21,000 Hz
Power Handling 
  • RMS: 35 Watts
  • Peak:105 Watts
Sensitivity 92dB
Impedance 3 ohms

If you know a little about speakers then you must have certainly made contact with a JBL because this is one of those brands which has extended so far in an industry that you can’t simply avoid it. No reason to do so as well, the JBL GTO429 at hand are some of the best 4 inch car speakers on the market as of now and that is perfectly embodied through their build quality.

Speaking of quality, these JBL 4 inch speakers use  the brand’s Patented Plus One woofer-cone technology which provides more overall speaker-cone area than other cones in its class, and as you might already know, the larger the cone area, the more air a speaker radiates. Additionally, their carbon-injected cone material produces a lighter and stiffer cone which allows for a better low-frequency response.

As for the highs, these JBL GTO429 speakers feature edge-driven silk balanced dome tweeters which ensure a rich experience in the upper frequencies, defined by a bright, open quality.

These JBL 4 inch car speakers are rated for a sensitivity rating of 86dB and can handle up to 35 watts of power on continuous basis.

The best thing about these speakers is their high sensitivity rating coming in at 92dB. If this means anything, It means that these speakers will sound awesome running off a low-powered stereo system, but they’ll really shine when paired to an outboard amplifier.

5. Alpine Type-S SPS-410

Size 4 inch
Design 2-way
Frequency range 97 – 22,000 Hz
Power Handling 
  • RMS:  45 Watts
  • Peak: 140 Watts
Sensitivity 86dB
Impedance 4 ohms

SPS-410 is another great set of 4″ inch speakers by Alpine, which is another well-established car audio brand. Indeed, this is one of the brands which have raised the bar higher for the competition so much that it’s almost impossible to match up to it.

The price tag on these speakers might be slightly higher than the rest of the speakers on this list but the Alpine Type S-SPS-410-A speakers are as powerful as they could be. With a peak power of 140 watts and a 45 watts RMS, these speakers will do quite well running off a factory head unit, not to mention when you hook them up to a powerful outboard amp.

Alpine Type S-SPS-410-A 4 inch car speakers are featured with mineral-fortified polypropylene woofer cones which are exceptionally stiff, yet lightweight allowing them to push out well refined bass. These cones are supported with resilient rubber surrounds to help keep the woofers centered for accurate cone movement.

As far as highs are concerned, these speakers use 3/4″ silk dome tweeters which are designed to provide warm high notes that bring out the character of the instruments and vocals.

All in all, Alpine Type S-SPS-410-A 4″ car speakers can deliver amazing lows, mids, and highs.

6. Kenwood KFC-1094PS

Size 4 inch
Design 3-way
Frequency range 110 – 20,000 Hz
Power Handling 
  • RMS:  35 Watts
  • Peak: 145 Watts
Sensitivity 86dB
Impedance 4 ohms

Last set of speakers is from Kenwood which is one of the most established brands in the car audio industry. Kenwood offers a wide range of quality products for a very affordable price and the KFC-1094PS speakers are no exception.

The speakers at hand are great for anyone who’s on a budget and looking for a decent replacement to their worn-out stock speakers.

Kenwood KFC-1094PS speakers are one of the fewest 4″ speakers to feature 3 way design. While most full-range speakers use 2-way design which consists of a woofer for the lows, and a tweeter mounted onto the woofer to produce the highs, 3-way speakers use an extra sonic driver called the midrange whose role is mid frequencies reproduction.

That said, these speakers are featured with polypropylene woofer cones with a Diamond Array pattern that increases strength, improves bass response, and keeps distortions to a minimum. These woofers are supported with rubber surround for accurate cone movement.

Since these are 3-way speakers, you’ll also find a 1-3/16″ water-resistant paper cone which covers mid-range frequencies, as well as a 1/2″ ceramic flat tweeter which broadcasts the high frequencies effectively to complete the all-round coverage.

Kenwood KFC-1094PS speakers can handle up to 35 watts of power on continuous basis and are rated for a sensitivity rating of 86dB.

The only downside to these speakers, conceivably, is their relatively narrow frequency range.
