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. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. 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.

Needed to replace factory speakers due to one of them was blown. New speakers are crisp and clear. If you want deep bass these will disappoint, but mostly because of factory stereo. Easy installation and instructions were fabulous.
Pros:
Easy to install, crisp and clear

BEST SOUND FOR THE MONEY!

Crutchfield Customer Review (What's this?)
 
All-around great speaker...Great highs and mids...if you are looking for a speaker with big thumps this is not the one for you. However the have the right amount of bass for a front door speaker. Crisp and clear sound make this a great buy!
Pros:
Crisp Highs and Mids!!
Cons:
If you are looking for a thumping bass...not the product for you!

Flat

Crutchfield Customer Review (What's this?)
 
Theses speakers sound clear & good, BUT flat.. They have no bass what so ever... I do know that a 6.5 speaker is not going to put out much... But I wanted something more.. I ordered some Sound Ordance (SO) for the same price & installed them and WOW what a difference... So needless to say these was sent back for a fast and easy refund.. Love You Guys @ Crutchfield......
Pros:
Clear & Good
Cons:
FLAT & no bass at ALL!

Written By Money Mike, Savannah, GA on Tuesday, May 21, 2013
 
Please don't waste your money! Kenwood should be ashamed to make a product that can't even outperform a 10 year old factory speaker system.
Pros:
Good hi's
Cons:
Bass and mid range. Entirely too much distortion at higher decibels.

Installed in a 2000 GMC Yukon XL
Crutchfield Customer Review (What's this?)
 
The Speakers sounds pretty good for the money.I was torn by Sony MTX and Kenwood. After looking at the specs Kenwood pretty much match everyone and beat them by the cost.
Pros:
The speakers fit perfectly speacially with the all the free parts that Crutchfield included. You can't beat free!
Cons:
It took a little time to get here specially when your current speakers had a tear and it sounded horrible when playing music with bass.
