Kicker Speakers: Are they any good? [Our Review]

Kicker was introduced with a specific focus on car audio systems; therefore, it’s no wonder it’s one of the best brands currently featured on the market. In 1973, the brand was launched from Steve Irby’s garage.

He launched the company with the amazing Original Kicker.

This was the first full-frequency range speaker that was specifically meant for trucks and cars.

This set the tone for Kicker’s impressive future as a trendsetter and innovative company.

Today the brand is known for its wide range of products that offer vehicle owners quality options to upgrade their cars’ sound systems.

Kicker enables sound systems to provide sound experiences that equal live concerts, thanks to powerful speakers that can handle high volumes and provide clear mid and high frequencies.

They make sure it stays modern and relevant to today’s audiences. It incorporates modern technology and expands the range to different markets when necessary.

This includes:

  • Bluetooth speakers
  • Bluetooth headsets
  • Noise isolating in ear headsets

Kicker still operates from Oklahoma in the US, but exports to over 50 countries worldwide. It sets a standard and makes sure to keep on meeting that standard via constant reinvention.

Let’s have a look at some of their speaker series and I'll review a few of their most popular models too.

Kicker Speakers Series

  • QS
  • KS
  • CS
  • DS

Kicker’s DS coaxial units are designed to offer vehicle owners an easy installation option.

You can literally drop these speakers into the existing speaker box and have an instant upgrade.

It may be a user-friendly option, but in no way did Kicker drop their level of quality.


The following features ensure you can enjoy advanced sound quality in your vehicle:

  • Quality magnets
  • Advanced motors that can cope with amplifiers’ power
  • Polypropylene cones

Their classic-though-modern look means any driver will love installing these speakers, as they look as stunning as they sound.

Kicker Speakers Reviews

1. Kicker 40CS654

This speaker looks as spectacular as the features it provides. If you purchase this unit, you get a strong, durable, powerful speaker. The 6.5" version of the CS line is one of the most popular speakers from Kicker.

  • Sensitivity: 90 dB
  • RMS: 100 Watts
  • Peak Power: 300 Watts
  • Frequency Response: 40-20,000 Hz
  • 2way/3way/4way: 2-way Coaxial 

The speakers can handle up to 100 watts of power each, which is remarkable for speakers of this size.

You can use them connected with your car’s original sound or hook them up to an amplifier.


They will handle the power and produce excellent sound.

The quality sound is thanks to:

A balanced dome tweeter

Polypropylene woofer

The mentioned woofer is safely ensconced in a polyester foam surround.

This affords some protection against shock, but also helps to improve the sound production. If you love the low tones that woofers produce, take note that these aren’t designed to give you pounding beats.

You’ll get some bass sounds, but if that should be the focus of your system you should invest in additional sub woofers.

If you plan to install the system yourself, you’ll be happy to know they simply slot into existing speaker spaces.

This is possible thanks to reduced depth baskets that take up very little space, so you don’t have to build customized boxes for the speakers.



2. Kicker 43DSC6504

This Kicker model is a unique design, so before you purchase them, make sure they’ll fit into your car. If they don’t, you’ll have to build customized storage boxes.


  • Sensitivity: 92 dB
  • RMS: 150 Watts
  • Peak Power: 450 Watts
  • Frequency Response: 30-20,000 Hz
  • 2way/3way/4way: 2 Way 

Though they’re made to afford easy upgrade options through features such as the reduced depth baskets, the oval shape may be a problem in some cars.

The mounting depth is slightly more than many other speakers, so make sure it will work before you buy these.


If you get these to fit your car, you’ll love the sound they produce, because the 40CS6934 units support an expansive range of tones.

Though any basic speaker will struggle to produce bass notes as strong as subwoofers, these speakers afford quality low tones.

It will suffice in most cases, unless you’re set on getting bass effects that you can feel as well as listen to.

If you love what you’re hearing, you’ll appreciate the fact that these speakers are well protected and will last you a long time.

This prevents damage from shock, wear and tear.

In the woofer cone, you’ll find a polyester foam surround, and the baskets are made from strong materials.



3. Kicker 43DSC6504

This is perhaps Kicker's best selling 6" by 9" speaker. It's a 3-way speaker which I don't always recommend if there's a 2-way option, but these are proper good speakers despite that. They made in into my list of the best 6x9 car speakers given the great value for money they offer.


  • Sensitivity: 90 dB
  • RMS: 60 watts
  • Peak Power: 240 watts
  • Frequency Response: 40-20,000 Hz
  • 2way/3way/4way: 3-way

This unique model is a winner in Kicker’s range, thanks to these amazing features:

The speakers can handle quite a lot of power for their size

The tweeters don’t protrude much, which means there’s less chance of them being damaged


Extended Voice Coil (EVC) technology is used, which enhances the clarity of the sound

The foam surround helps to keep the speaker damage free, and it improves the quality of the sound the cone produces.

What adds to their uniqueness is that they’re flexible; this means you can install them in most vehicles’ existing speaker compartments, even if the shapes don’t completely align.

Flexing them slightly won’t break them or prevent them from producing excellent sound.

You need to keep the speakers’ limitations in mind; though they can handle a lot of power, they will deteriorate over time.

Low frequencies won’t sound as clear anymore and you’ll hear a lot of distortion.



4. Kicker 11KS65

ReviewThey aren’t top of the range, and only handle average amounts of power; this means you risk blowing them if you connect the speakers to an amplifier..


  • Sensitivity: 90 dB
  • RMS: 65 Watts
  • Peak Power: 195 Watts
  • Frequency Response: 40-21 000 Hz
  • 2way/3way/4way:  2-Way 

Though the speakers’ frequency response is quite good and the KS range is meant to help you achieve powerful low tones, no speaker is an adequate replacement of a subwoofer.

You may want to test these out before purchasing them.


The durability of the speakers is improved by the santoprene surrounds of the woofer.

You receive a 1-year warranty when purchasing these, which should lay your fears to rest about the speakers’ quality.



Final Thoughts 

Kicker is an exceptional brand that aims to bring practical, quick solutions to its customers.

The various ranges cover most requirements that vehicle owners may have, so you’re sure to find a speaker that fits your preferences.​
