Kicker

Why replace your factory speakers?

The speakers that originally came in your car were made from inexpensive materials, designed to create acceptable sound at the lowest possible cost to the manufacturer. If you love music, you deserve better. Name-brand aftermarket speakers deliver fuller, richer sound with considerably more detail and nuance, and they're capable of playing louder and cleaner than factory speakers. Connect new speakers to your factory radio and you'll get the best possible sound from your dealer-equipped system. Pair them up with a new car stereo for a level of enjoyment that can rival a high-fidelity home audio experience.

Our take on the Kicker 40CS674

by John Pollard

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.  

Built tough

Kicker's 40CS674 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 1/2" PEI balanced dome tweeter takes care of the vocal and instrumental details that'll really bring your music to life. These speakers sound great powered by a factory radio or an aftermarket car stereo, and they'll really rock when connected to an external amplifier. Grilles are included.

Highlights:

  • 2-way 6-3/4" speakers (pair)
  • polypropylene woofer cone with polyester foam surround
  • 1/2" PEI balanced dome tweeter
  • power range: 2-100 watts RMS (300 watts peak power)
  • frequency response: 40-20,000 Hz
  • sensitivity: 90 dB

    Kicker 40CS674

    Written By Scotty, Bridgeport, CT on Sunday, May 19, 2013
     
    Very good sounding speakers--they handle bass very well for their size and I'm happy with them for the price. The only thing I really didn't like about them were the speaker connections--so darn flimsy! I bent them more then once trying to connect them to the wires--I mean how much more would it cost to put sturdy connectors on it??? Not built at all like the old days! And let me tell you--I've been around the block! LOL!
    Pros:
    Handles bass very well for the size and costs!
    Cons:
    Flimsy wire connectors!

    Quality speakers, reasonable price. Crutchfield advisor did a great job in recommending these speakers. They were an exact size replacement for the old stock speakers. The instructions were great in that they included how to remove the door panels step by step. Saved a lot of time trying to figure it out.
    Pros:
    Great quality, great sound fantastic bass control
    Cons:
    None

    Easy Install, Great Sound

    Written By Mike, Western PA on Sunday, May 12, 2013
    Installed in a 2002 Chevrolet Avalanche
    Crutchfield Customer Review (What's this?)
     
    For the money, these were a perfect choice for the rear in my 2002 Chevy Avalanche. They are a great complement to my recently installed Kenwood components up front. They kick out surprisingly nice base- no you won't vibe someone a mile away. But for classic rock to country and today's top 40, they are enough.
    Pros:
    Easy install and great sound.
    Cons:
    None found yet.

    WOOT

    Crutchfield Customer Review (What's this?)
     
    Put them in the doors of my Miata. Popped right in after I drilled an extra hole.

    I am pretty picky with my home audio equipment, so I consider my bar to be set pretty high. These speakers sound just fine. They are clean and can put out a lot of bass, very strong into the 40s. Most music plays just fine. You will only miss the lowest lows.

    I am really happy with them; I don't need a subwoofer.

    It took me less than an hour to pop these into the front doors of my GMC 2500 crew cab, I tested the drivers side before I started the passenger side and was imediately impressed. With both sides done the improvement over stock is amazing. I cant wait to get the rears done now!!
    Pros:
    Super easy install
    Cons:
    Not enough time to do rears/ they dont just install themselves.

    Sounds great

    Written By DicTrees, Long Island NY on Friday, April 05, 2013
    Installed in a 2013 Chevrolet Sonic
    Crutchfield Customer Review (What's this?)
     
    I have a 2013 chevy sonic. They fit in the front doors with the speaker adapters crutchfield supplied for free. I had to snip some mounting tabs on the adapters since these speakers are 6.75 and the brackets are for 6.75 and smaller i am assuming these tabs i snipped are for the smaller speakers. They replaced my 5.5 stock speakers with no problems. They sound great and produce lows and mids that my factory speakers couldn't. Very happy with these kicker CS speakers. I plan on doing my back doors soon with the same set.
    Pros:
    Sounds great, super clean, great highs and mids, decent bump'n for 6.75"
    Cons:
    they dont install themselves
