Top 5 4-Inch Car Speakers Reviews

Polk Audio is a pretty big name in the audio industry, with a wide array of audio equipment for every purpose.

We've reviewed various Polk Audio car speakers on this site before, particularly the dB series speakers, which are popular and seem to be well-liked.

Polk Audio give their car speakers a bit more of a minimalist look. The dB series speakers for example feature a very bright stainless steel mounting hardware and db-design grilles that will add a nice touch to your car's interior.

Polk Audio DB401 are versatile speakers. They feature a multi-hole mounting pattern and shallow depth of 3/4-inch which allows for easy drop-in installations, practically in any car on the road.

Moreover, these speakers are marine certified, so they are also perfect for use in boats of all types.

Polk's db401 speakers are made with high quality materials that won't fall apart under stress, excessive use, heat or time. These speakers are equipped with Liquid-cooled 3/4" silk/polymer dome tweeters that use powerful Neodymium magnets to produce accurate highs for bright musical details.

They are also equipped with polymer/mica composite made woofers as well as durable rubber surround for long lasting.

Additionally, The built-in two-way crossovers stream sound frequencies to the suitable driver (lows to the woofers,and highs to the tweeters) for better stereo imaging and sound-stage.

  • Sensitivity: 91 dB 
  • Power Handling: 135 Watts (Peak) / 45 Watts (RMS)

2. Infinity REF-4002CFX 4" Coaxial Car Speakers

We have done a few reviews on Infinity Reference speakers before; They have above par products for more than a reasonable price.

This pair of speakers is great for somebody who doesn't listen to heavy bass tracks very often.

The REF-4002cfx features solid polypropylene woofers that are built putting Infinity's patented Plus One+ woofer technology in use, which allows the woofers to have a significantly larger cone compared to speakers of similar size.

Despite the relatively larger cones that the Reference 4002CFX speakers are equipped with, we've found that these speakers are a bit lagging behind the competition in terms of bass reproduction.

However, when it comes to mid and highs, that's where these speakers really shine.

TECHNICAL FEATURES

  • Design: 2-Way
  • Sensitivity: 92 dB 
  • Power Handling: 105 Watts (Peak) / 35 Watts (RMS) 
  • Frequency Response: 75-21,000Hz 
  • Impedance: 4-Ohms

Pros:

  • Great Sound Quality
  • Easy Install
  • Good bass from such a small size and mid and treble are great.

Cons:

  • Connectors seem a bit flimsy, use caution when wiring.
  • The mounting hardware, speaker wires and speaker grills were not included with the purchase.
Infinity REF-4022cfx 105W 4" Reference Series Coaxial Car Speakers with Edge-Driven, Textile tweeters - Pair
  • 105 watts max Each, 35 Watts RMS each
  • Edge-driven, textile tweeters
  • Plus OneTM woofer cone
  • 3.0 ohms impedance
  • Sensitivity: 92 dB

3. Rockford Fosgate P142 4-Inch Car Speakers

The Rockford Fosgate P142 is one of the best 4-inch car speakers on the market mainly because of its larger cones. By taking advantage of the VAST proprietary technology, it comes with larger than usual cones that allow for more space for the sound to vibrate and reproduce accurate sound with excellent frequency response.

The
PS142 also comes with a mineral-injected polypropylene woofer cone that’s wrapped with a rubber surround that gives it just enough stiffness to minimize any excess shaking when playing music at higher volumes. At the same time, the PEI tweeters make sure that you can hear but the lows and the highs when playing music through the P142.

Last, but definitely not the least, the
P142 is remarkably easy to install. Although we normally wouldn’t recommend it for first-time DIYers, you can actually install it yourself even if it’s your first time. This is especially because of the concealed crossovers, so you don’t have to worry about cleaning up all the connecting wires since they’re all neatly hidden away inside the speaker’s basket.

As a bonus, the speakers have screw holes that fit in perfectly with most factory car stereo holes for easy installation.

TECHNICAL FEATURES

  • Design: 2-Way
  • Sensitivity: 86.5 dB 
  • Power Handling: 60 Watts (Peak) / 30 Watts (RMS) 
  • Frequency Response: 100-22,000 Hz

Pros:

  • Easy to install 
  • Durable 
  • Compatible with high-powered stereos/speakers 

Cons:

  • Doesn’t come with grilles

  • Famous Rockford Fosgate build quality with a full 1-year warranty when purchased from an authorized Rockford Fosgate reseller

Are you on a budget? If you are, then this pair of 4"x6" speakers is quite an appealing option, both for its low cost and awesome looks.   

Housed inside a lightweight blue poly injection cone that gives it the necessary stiffness to withstand is a three-way sound speaker system with 1-inch ASV voice coils and a 20-ounce magnet. Both of these combine to help give the speakers a wide frequency response and the capability to handle higher wattage and temperatures.   

On top of it all, these speakers have a 1-inch neodymium film dome for smooth and detailed sound with DIY-friendly installation that supports most vehicle’s factory screw holes.   

Unfortunately, build quality is lackluster. These speakers can break down on you or come unmounted while driving. However, for the price, it’s hard to complain if you can get at least a year or two of service out of these.

  • Sensitivity: 89 dB 
  • Power Handling: 240 Watts (Peak) / 120 Watts (RMS)

The TS-F1034R by Pioneer is one of the more economically sound out of all the speakers we reviewed so far.

However, we think these speakers are great for the price. I mean, less than $25? That is a major bargain.

And like many Pioneer A series speakers we reviewed here, these speakers feature a sleek, futuristic look.

The Pioneer TS-F1034R are above par speakers compared to factory installed speakers. That being said, if you're looking for a decent and easy replacement for your worn-out speakers without splurging too much, then TS-F1034R would be a great buy.
