It's time for an upgrade

Upgrading the old factory speakers in your car will give you a huge bump in sound quality, and Kicker designed CS Series speakers to get your sound system rockin' without breaking the bank. You'll enjoy your music even more when you hear all the details that your muddy-sounding factory speakers couldn't begin to reproduce.  

Bring on the treble and the bass

Kicker's 40CSS674 component speaker set provides low-end from a tough 6-3/4" polypropylene woofer, with a polyester foam surround that will stay strong for years to come. The separate 3/4" titanium dome tweeter takes care of the vocal and instrumental details that'll really bring your music to life. The outboard crossover network allows you to pick from three different tweeter level settings so you'll get balanced sound wherever you're sitting. Grilles are included.

Product Highlights:

  • component speaker system includes 2 woofers, 2 tweeters, and 2 crossovers
  • 6-3/4" polypropylene woofers with polyester foam surrounds
  • 3/4" titanium dome tweeters
  • external crossover network with 3 tweeter levels (0, +3, +6 dB)
  • power range: 2-100 watts RMS (300 watts peak power)
  • frequency response: 35-21,000 Hz
  • sensitivity: 90 dB
  • top-mount depth: 1-7/8"
  • warranty: 1 year
  • Our 60-day money-back guarantee

Why install component speakers?

A component speaker system gives you the best possible performance from your car audio system. A system consists of separate woofers, tweeters, and crossovers, each designed to cover one specific range of frequencies. As separate components, the woofer can move freely to deliver more powerful performance, while the tweeter can be custom-mounted in a better spot up closer to your ears, revealing a whole new world of detail. Separate crossovers are far superior to the simple filters wired into full-range speakers, so the components work together for smoother, more focused sound.

Features

Polypropylene Woofer Cones: The Kicker CS-series speakers feature durable polypropylene woofer cones, resistant to the moisture and temperature extremes found in automotive applications.

Ribbed Polyester Foam Surrounds: The ribbed polyester foam surrounds allow extended cone excursion for additional bass output and higher SPL.

Tweeter Mounting Options: The tweeters come with brackets to allow multiple mounting configurations: flush-mounted, angled flush-mounted (approximately 10°), and angled surface-mounted (approximately 15°).

Tweeter Dimensions:

  Flush Mount Angled Flush Mount Angled Surface Mount
Mounting Height 0.238" 0.563" 1.272"
Depth 0.532" 0.612" 0.554" (screw depth)
Frame Diameter 1.976" 1.976" N/A
Cutout Diameter 1.57" 1.587" N/A
Frame Width N/A N/A 1.688"
Frame Length N/A N/A 1.897"

Crossovers: The component system includes passive 2-way crossover networks for a seamless transition between the woofers and tweeters. The slope is 12dB per octave (both high pass and low pass) and the crossover point is 4000 Hz. A switch on each crossover allows you to set the tweeter output; 0 dB, +3 dB, or +6 dB. The crossovers' input and output wires are attached; the woofer output has quick slide terminals that connect directly to the woofer and the tweeter output has bullet terminals that mate to the terminals on the tweeter wires. The crossovers' dimensions are:

  • Length: 4.595"
  • Width: 2.463"
  • Height: 1.004"

Crutchfield Customer Review (What's this?)

Nice sound. A good improvement over the factory speakers

Pros: Nice Sound

Cons: Mounting instructions left something to be desired. Had to fabricate the mounting for the tweeters. The screws and clips are poor quality and had to use many of my own because of the ones provided stripped out.

What can I say, they're Kickers they sound great.

Pros: Nice package, crossover, tweeter and woofer produce a very sweet sound on all genres. Adapter fit perfect.

Love the speaker they sound great. Would definitely recommend the speakers.

Excellent Speakers!!!

Written By Rick, Chicago, IL on Monday, March 24, 2014

Crutchfield Customer Review (What's this?)

I was looking for speakers to replace my factory 6 3/4 door speakers that would also complement my amp. I was unsure at first as to whether to go with a component setup but after speaking to a Crutchfield advisor and other friends I decided to go with the Kicker 40CSS674. Once I got them installed and connected I must say these were great speakers with quite a bit of power the the highs sound great! I am thoroughly pleased with their performance so far and I definitely recommend these to anyone looking for a moderately priced pair of component speakers.

Pros: Power, very clean/clear, easy to install

Cons: None

Pros: Sounds great and bass is good

Kicker components

Written By Hyker, Brodalbin NY on Friday, August 30, 2013

Crutchfield Customer Review (What's this?)

Sound great at low speeds and low volume. Can hear them and still sound great. They are in a convertible so all the low end response goes literally out the 'windows'. Looking to get a small sub to full the void.

Pros: Quality sound for the cost.

Cons: Lack of instruction for the multi use component 'tweeter' mounts. I felt I had to guess.

Watch the tweeters

Written By Jared, Central, PA on Tuesday, August 13, 2013

Crutchfield Customer Review (What's this?)

The speakers sound amazing. As is to be expected. The only REAL issue is the box that comes to adjust the tweeters. The idea is great, however, it is a challenge to find a good place to put them where they can still be adjusted, but out of the way. I ended up just having to play with it for a while, and then keep it in the door. To adjust it now I have to take the whole door panel off. But, other than that, the speakers are great.

Pros: Sound Quality

Cons: Space options

Pros: quality and value

Cons: none

Good factory upgrade

Pros: worth the money. Have them powered by mtx 75.4 and they handle the juice really well. The tweaters are loud but can take some punishment.

Cons: midrange is good but depending on the voice its sometimes muddy

Thanks for your question. For information on comparing two or more models I would recommend reaching out to an Advisor by phone (1-800-324-9695) or online chat. They will be able to help determine the differences and help you make the best choice for your system and your budget. [ Krissy  Nov 18, 2014 ]  Staff
My 2000 blazer was night and day but I they were 12 year old speakers I like the mids and highs the kicker components give and with the right songs my mirrors shake without a sub [ JAMES D  Dec 26, 2013 ]
Also depends a lot on your amp. I have 7 these speakers need a good amp to really go [ MICHAEL  Dec 26, 2013 ]
If you have a good spot for your tweeters (upper dash) these will blow up factory system away. But again look at you frequency range. These won't go as low as your factory speakers. They're louder, cleaner, and plays better mid bass. To really complete your system. Run a set of these and a sub. Or in my case 2 sets of these and two l7 [ MICHAEL  Dec 26, 2013 ]
This package contains two woofers, two tweeters, and two crossovers. Feel free to reach out to an Advisor by phone or chat for advise on which speaker set will be best for your vehicle. [ Jeff  Nov 25, 2013 ]  Staff
