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 QS series offers you the best of the company’s features and workmanship.

The range includes component and coaxial units that feature Kicker’s signature technology:

  • On the component systems, you’ll find Kicker Tri-Tech cone technology
  • On coaxial units, you’ll enjoy the effects of Kevlar-impregnated polypropylene
  • Tetoron dome tweeters
  • Metallized polypropylene capacitors

These all work together to offer you exceptional sound, as if you’re listening to it live. With easy installation features, Kicker makes sure anyone can partake in this experience.

Kicker Speakers Reviews

The 41QSS654 QS Series component system from Kicker is a quality setup that delivers a stunning midrange and versatile installation options to best fit a variety of vehicles. Kicker is known for innovative designs and intense power and the QS series lives up to this reputation.

The 41QSS654 system includes two 6.5” Tri-Tech woofer cones and rubber surrounds, two 1.18” tweeters with Tetoron domes, two crossovers, grilles, and a variety of adapter brackets, mounting and trim rings and more to accommodate different installation options.



  • Bottom-mount depth: 2.5”
  • Sensitivity:  86 dB
  • RMS: 90 watts
  • Peak Power: 180 watts
  • Frequency Response: 50-22,000 Hz
  • Impedance: 4 ohms


The tweeters are tonally balanced and feature domes made from Tetoron. This synthetic material has some give for an intense audio performance while faithfully hitting the high range without sacrificing quality.

The Tri-Tech woofers fill in the midrange for a well-rounded audio experience.

Perhaps one of the most compelling features of the QS series component system is the flexibility. Mount the tweeters in the center of the woofers to use as coaxial units.

You can also use with the removable “bullet style” aluminum phase plugs mounted in the center of the woofers. In this application the tweeters can be installed separately for improved dispersion.

When mounted separately the tweeters can be flush-mounted to reduce the risk of damage and maintain the integrity of the system.

The 41QSS654 system also includes an external crossover network that allows for bi-amping capability to separately power both the tweeters and woofers.

The 41QSS654 system is also equipped with three-level tweeter attenuation that can be adjusted to 0 dB, +3 dB, and +6 dB, for powerful and precise audio when mounted off-axis from the listener.



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.



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.



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.



Kicker Accessories

To ensure you're getting the most out of your preferred Kicker speaker, it's better to use the brand's recommended accessories.

There's no need to look for essential items like amp mounts, install kits, or signal cables made by other brands because Kicker already has those.

If you're into stylizing your speakers, the company has a collection of products made for customizing the look of your sound system. You may utilize Kicker LED speaker rings and sub grilles to give your speakers visual appeal.


Several manufacturers resort to low-cost, copper-clad aluminum (CCA) to reduce the price of their accessories. While it is consumer-friendly, you can't overlook the drawbacks like less wire flexibility, higher internal resistance, and low corrosion resistance. These factors result in inferior sound quality, which is not something anyone would prefer.

Another cost-cutting strategy used by audio companies is to reduce the number of real copper strands and use a thicker, external PVC jacket to exhibit "quality." This leads to lower amp output because the lack of copper limits the capacity of the wire to transmit current.

Kicker wire products are made of oxygen-free copper (OFC) with full AWG spec. Expect peak power transfer as OFC wires have remarkable flexibility, strong corrosion-resistance, and minimal internal resistance.

Kicker Gear

Besides producing high-quality speakers, Kicker also made strides in the lifestyle category. If you're a fan of the brand, try its collection of clothing and other merchandise.

Several of its offerings are made for outdoor use. Kicker has backpacks, cooler bags, folding knives, and camp chairs.

The brand features mugs, tumblers, face masks, phone wallets, and many more for home and office use.

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.
