Focal ICU 100 Universal Integration 4" 2-way...
  • AI/Mg inverted dome tweeter
  • (integrated) 6dB/oct crossover
  • Max Power 80W

Consider this Focal choice if you require 4″ speakers with a high-quality sound at a reasonable price. Focal ICU 100 is universally compatible thanks to its minimal mounting depth and separate ears. It doesn’t require any interior modifications to be installed in any car.

Along with having a butyl rubber surround, the Focal ICU 100 speaker is a dependable addition to your car’s audio system. You get quite a performer with 40W RMS, only a little bit less than our top bass pick, the Maximo Ultra.

This speaker’s outstanding treble production is another reason we enjoy it. Compared to speakers that come with a car, its inverted tweeter, composed of aluminium and magnesium, produces superior treble. Additionally, its acoustic horn guarantees a crisp, clean soundstage.

This top-tier coaxial speaker has an inbuilt crossover just as any other one would. This feature makes it simple to connect the speaker to the other components of the audio system. This speaker’s polyglass cone is especially amazing because it contributes to preserving the track’s natural tone without adding any distortion.

  • Morel Maximo Ultra 402 Coax 4" 45W RMS Maximo Ultra Series 2-Way Coaxial...
  • Treated paper composite woofer cone with butyl rubber surround
  • Soft dome textile tweeter

Strong troupers are morel speakers. They are delightful to listen to, especially given their apparent concentration on even the smallest aspects. Usually, speakers this size are thought to be underwhelming performers, but not the Morel Maximo Ultra 402 4′′ speakers. Instead, these are cocky young men who solidly vow to shock your world. Little is lost by the small design in terms of their capacity. If anything, if you know what I mean, they can be gratingly loud.

The Morel Maximo Ultra 402 contains top-notch components in what I like to refer to as a banging body. Each of these components plays a vital part in how each speaker functions normally. And I must say, these units do not let us down, as we highlight in the Morel Maximo Ultra 402 entire review. Consider the butyl rubber surround on the treated paper composite woofer cone. Tonal notes can move unhindered on this strengthened core’s stiff but trembling surface.

With the aid of Morel’s external voice coil technology, each speaker endures intense heat and loud music with exceptional steadiness. The Morel Maximo Ultra 402 is well-suited for handling power. Undoubtedly impressive, 45 Watts RMS in a 4-inch car speaker, but these tiny drivers couldn’t function on much less. You’re off to a good sound experience in your car when you combine this with a Sony DSX-GS80 receiver.

Even in the face of impending collisions, steel woofer baskets ensure durability. The soft dome tweeters can handle enough power without experiencing too much distortion. Additionally, they release incredibly accurate highs. The crossover network is incredibly effective in dispersing sound waves. As a result, distortion is prevented by preventing sonic saturation.

Purchasing this package could ultimately transform your life. You’ll be hurrying to get behind the wheel every day if it’s installed, after all.

These 4-inch automobile speakers were tough-looking, and that is only reasonable to remark. They appear severe and have a hard exterior on their bodies, which conveys that they mean business. Polypropylene woofer cones with robust rubber surrounds are used in the Kicker 46CSC44.

Comprehensive Buying Guide: Choosing the Right 4 Inch Car Speakers

Selecting the right 4 inch car speakers involves careful consideration of several factors. Here’s a comprehensive buying guide to help you make the best choice:

Power Handling

Power handling refers to the maximum amount of power (measured in watts) that a speaker can handle before it starts to deteriorate or distort. If you often listen to music at high volumes, consider speakers with high power handling capabilities. However, it’s important to ensure that the speakers’ power handling matches your car’s audio system to avoid damaging the speakers.


Sensitivity measures how well a speaker can convert power into sound. It’s measured in decibels (dB). A higher sensitivity rating means the speaker can produce a louder sound output for a given amount of power. If your car’s audio system has a low-power output, a high-sensitivity speaker would be a good match.

Build Quality

The durability and sound quality of your speakers are largely determined by their build quality. Look for speakers made with high-quality materials. For example, woofer cones made from materials like polypropylene are lightweight and stiff, offering good sound quality. Rubber surrounds are durable and provide excellent speaker movement. Metal tweeters, on the other hand, produce bright, crisp highs.

Don’t Overlook the Frequency Response

Frequency response indicates the range of frequencies a speaker can reproduce. While you cannot expect deep bass from 4 inch speakers due to their size, speakers with a wide frequency response can still deliver a rich, balanced sound output, producing clear mids and highs.

Speaker Type

Car speakers come in two main types: coaxial (or full-range) and component. Coaxial speakers are all-in-one, with the woofer and tweeter combined in a single unit. They are easier to install and are generally more affordable. Component speakers, on the other hand, have separate woofers and tweeters for improved sound quality. They require a more complex installation but often deliver superior sound quality.

Consider the Brand’s Reputation

It’s often wise to choose speakers from a reputable brand. Renowned brands usually have rigorous quality control procedures and are more likely to offer customer support and warranties.
