Kenwood

Why replace your car's original 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 Kenwood KFC-1664S

by John Pollard

If you've been suffering with tired out speakers, Kenwood's Sport Series speakers are a cost-effective way to liven up the sound in your car. The KFC-1664S 3-way 6-1/2" speakers use multiple speaker elements to bring new clarity and enhanced performance to your car audio system.

Each speaker features a polypropylene woofer with a treated cloth surround that delivers full bass while standing up to the heat and humidity in your car. A balanced-dome midrange driver allows vocals and instruments to be heard more distinctly, while the ceramic tweeter supplies the musical details that make your music more exciting. The built-in crossover sends the appropriate frequencies to each element, so you'll hear clean, balanced performance. Grilles are included.

Highlights:

  • 6-1/2"/6-3/4" 3-way car speakers (pair)
  • injection-molded polypropylene (IMPP) woofer with cloth surround
  • 1-3/16" PEI balanced dome tweeter
  • 1/2" ceramic piezo tweeter
  • grilles included
  • power range: 2-35 watts RMS (180 watts peak power)
  • frequency response: 35-22,000 Hz
  • sensitivity: 92 dB
  • top-mount depth: 1-3/4"
  • warranty: 1 year
  • Our 60-day money-back guarantee

    Our Product Research Team

    At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.

We stay on top of new products and technologies to help people make informed choices.

    Features

    Woofers: The woofer cones are constructed from injection-molded polypropylene. This process of cone molding assures a uniform cone thickness for superior linearity and clarity. The cones are lightweight and rigid for low distortion and good bass response. Each woofer uses a treated cloth surround.

    Tweeters: Each speaker has a 1-3/8" PEI balanced dome tweeter. A semi-dome tweeter has a dome placed inside a cone. Balanced dome tweeters are semi-dome tweeters with equal reproduction area given the cone and dome portions of the tweeter.

    Flat Super-Tweeters: The speaker also utilizes a 1/2" ceramic, flat super-tweeter for added high frequency reproduction.

    Mounting: The speakers can be mounted in three-hole and four-hole 6-1/2 applications. They can also be easily mounted in 6-3/4 applications, but because the extra screw holes create an air leak in the larger opening, a speaker baffle must be used.

    Very good sound at a fair price. Put this in my 99 Trans Am and it blended with the other speakers in the Monsoon system to give excellent sound.

    I really like these speakers and can't wait to complete my setup. I have them in my door panels and they are great sounding and crisp with the highs while delivering the bass and mid to complete the sound.

    Great for the price

    Written By Nick, Fort Wayne, IN on Tuesday, March 05, 2013
     
    I received these as a gift to replace the factory speakers in my '98 Blazer. For the price these offer great sound. However, the bass is lacking and disappears completely at higher volume. This wasn't much of an issue to me personally, as I have an amp and sub that I'll be installing when the weather permits or I can get into my buddy's shop. You're better off buying something else if you want decent bass out of just door speakers.

    I will be buying another set of these to replace the speakers in the rear doors soon.
    Pros:
    Cheap, great sound, easy install
    Cons:
    Very little to no bass at any volume

    Written By Phil, Superior, AZ on Monday, February 18, 2013
    Installed in a 2012 Jeep Wrangler
    Crutchfield Customer Review (What's this?)
     
    Great radio at a very good price. This radio is full of great features at a low price which, when Crutchfield's great service is factored in, makes it inexpensive. The HD radio works flawlessly and reception of both AM and FM is great. The ability to utilize an AUX or USB input is another great feature. And the hidden CD slot behind the head unit's drop down door means it'll keep a great deal of dust out of the radio's internals.
    Pros:
    Inexpensive. Great AM/FM reception. Ample power. And now read the list of features....too lengthy to list here.
    Cons:
    The dim-able display offers only one 'step' so, for my eyes, it's either to bright at night and OK in the day, or too dim in the day and OK at night. Not a big deal and not a deal breaker.

    The three way provides good tone from low to high. The outer flange where the screw holes would have been nice if it was more flatter at least for 93 Honda. Overall its a good replacement from stock.
    Pros:
    Sounds good. Easy install.
    Cons:
    Its not the best but for the price, i think its a good deal!

    Mid-priced, mid-quality

    Written By Forzatus, Sioux City, IA on Thursday, January 31, 2013
    Installed in a 2008 Chevrolet Colorado
    Crutchfield Customer Review (What's this?)
     
    As anticipated for the money I spent, these speakers were a minimal improvement over the factory Blaupunkt 15W paper speakers that came with my 2008 Chevy Colorado LT Crew Cab, which had terrible sound to begin with....I hooked 4 of these up to a Planet Audio 150x2 amp, in parallel by side (L & R), giving about ~37.5W RMS per speaker @ 2 ohms. I also tried running them directly from my Pioneer FH-X700BT deck, at ~14W each, and they sounded about the same as the factory speakers. This amp sounded great with my old Boston 6 1/2" speakers I had in a previous vehicle. Even with the Speaker Baffles in the doors, they just don't give much of a punch at all, and the highs leave something to be desired. I added a set of 3/4" Tweeters to make up for it, but the audio quality is still not the level I'd like. For the money I spent, I can't complain too much, as they were an improvement, if only minimal, from the stock speakers. I'll be adding 8" subs in the back seat to give me the bass I want, but I may look at replacing these door speakers for a better mid to high range sound in the future.
    Pros:
    Cheap, easy to install with the included kit from Crutchfield.
    Cons:
    Not much low range to be had, mids sound OK, highs are weak. Recommend buying either a more expensive set of 6-1/2's, or a set of tweeters to offset this shortcoming. Minimal improvement over factory speakers even with an amp.

    Crutchfield Customer Review (What's this?)
     
    purchased these week ago and installed them today. can honestly say my OEM speakers had more bass and depth overall even when they were blown. speaker wire hooks ups worked good instalation was tricky as the new mounting brackets and hardware i got with them kinda sucked using little screws and nuts. after paying for the 4 of them im not really to fond of them. sound to have a little to much flutter when bass hit or high notes. for the price for each front and back i guess i cant complain. thought kenwood was better quality!!!
    Pros:
    wiring was great.
    Cons:
    mounting brackets and hardware kinda sucked and was a pain.

    Crutchfield Customer Review (What's this?)
     
    They really don't sound that much better than the factories I replaced. Maybe they need more power. Only pushing them with JVC head unit. Also mounted in doors. Maybe that's the problem. I remember Kenwood used to be great. I would not recommend these.
    Pros:
    Price
    Cons:
    Not much better than factory in 98 Sonoma doors.

    Nice Speakers, Poor Installation Kit

    Written By Anonymous, Farmington Hills, MI on Sunday, January 20, 2013
    Installed in a 2007 Chevrolet Monte Carlo
    Crutchfield Customer Review (What's this?)
     
    Overall, I like the sound quality of these speakers, but the installation kit provided for the front doors of the 2007 Monte Carlo did not work out at all. The adapters were not needed (nor did they fit), as the speakers fit perfectly in to the mounting plate found on the car. The wiring harness adapter did not come close to plugging in to the factory harness. I had to splice in to the factory wiring and use the wiring that came with the speakers. I also bought a pair of these speakers for the rear deck--the adapter and wiring harness for the rear worked out perfectly. If this came with a harness that worked in the front doors, this would be a five star review.
    Pros:
    Good sound quality for a relatively inexpensive speaker
    Cons:
    Front installation kit did not fit.
