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 Speaker

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.

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.

 Infinity REF-4002CFX

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.

Infinity REF-4002CFX Specifications

      • Design : 2-Way
      • Sensitivity : 92 dB
      • Power Handling 
        • RMS  :  35 watts
        • Peak  : 105 watts
      • Frequency range : 75-21,000 Hz
      • Impedance : 4 ohm

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.

  • 105 watts max Each, 35 Watts RMS each
  • Edge-driven, textile tweeters
  • Plus OneTM woofer cone
  • 3.0 ohms impedance
  • Sensitivity: 92 dB

Alpine is a brand that we haven’t discussed much on our site.

However, they have made a name for themselves in in-car audio equipment, mobile multimedia components, and in-car navigation systems.

Alpine SPS-410 speakers feature mineral-fortified polypropylene cones that are stiff, yet lightweight, which allows for accurate bass and clear midrange.

Alpine Type-S SPS-410

The resilient rubber surrounds on the other hand help keep the woofer centered for accurate cone movement, resulting in reduced distortion.

These speakers are also equipped with silk dome tweeters that provide warm, bright highs.

If I had to pick some criticisms for the SPS-410, I'd have to say that these speakers lack much bass, but the range of highs and mids are perfectly enjoyable.

With that being said, these speakers are not suitable for bassheads, and unless you have an external amplifier and subwoofer installed, you won't get much bass out of these.

Alpine Type-S SPS-410 Specifications

      • Design : 2-Way
      • Sensitivity : 86 dB
      • Power Handling 
        • RMS  :  45 watts
        • Peak  : 140 watts
      • Frequency range : 97-22,000 Hz

PROS

  • Good sound great replacement for factory speakers
  • Affordable pricing
  • Nice clean sound as a dash speaker
  • Affordable Quality
  • Easy installation

CONS

  • Not much bass
  • No adapter offered for this application

  • Make sure this fits. by entering your model number.
  • Features: 4" 2-way speakers, Carbon fiber-reinforced plastic woofer cone with specialized rubber surround, 3/4" silk dome tweeter, Handles up to 45 watts RMS (140 watts peak power), Frequency response: 97-22,000 Hz, and Grilles not included

This pair of speakers from Kenwood is great for those who would like the Kenwood name without having to spend a lot of money on an expensive pair.

The price of Kenwoods are usually at a perfect balance.

The KFC-1094PS speakers are one of the fewest 3-way 4 inch car speakers on the market.

Kenwood KFC-1094PS Car Speakers

Unlike 2-way speakers which consist of a woofer for the lows, and a tweeter mounted onto the woofer to produce the highs, 3-way speakers have an extra driver called the "midrange", which is responsible for mid-range frequencies reproduction.

The Kenwood KFC-1094PS speakers feature polypropylene woofer cones with a Diamond Array pattern that increases strength, improves bass response, and keeps internal vibrations and other distortions to a minimum.

Additionally, the rubber surrounds allow for accurate cone movement, withstands weathering and provides reliable support that keeps your music playing.

If I had to pick any cons, it would be the narrow frequency range – while most 4 inch speakers can reach as low as 70Hz, the Kenwood KFC-1094PS speakers are stuck at 110 Hz, which negatively affects Bass.

Moreover, these speakers are rated at a sensitivity rating of 86 dB which is low compared to the other speakers we reviewed here.

      • Design : 3-Way
      • Sensitivity : 86 dB
      • Power Handling 
        • RMS : 35 watts
        • Peak : 140 watts

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.

Pioneer TS-F1034R 2 Way Speakers

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.
