Our take on the Kenwood KFC-1664S

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.

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.

This is just what I needed. From past experience with Crutchfield, I knew I could depend on them for good products and service.

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.

Versatile, and good-sounding

Written by Matt Freeman, Staff Writer - Creative, on 10/10/2013 2:45:00 PM
Not too long ago, we helped a teen install his very first car stereo system. In his doors and his rear deck, he installed two pairs of these 6-1/2" Kenwood speakers. And I have say, after helping with the installation and listening to them play, I highly recommend them to anyone looking for an inexpensive and quick upgrade. The sound was solid. Good high notes without being crispy, and reasonably solid bass. A huge step up from old factory speakers, no question. Looking at the specs, you'll see they're very efficient, which I can attest translates into pretty good volume levels. What I really was impressed by, though, was how friendly they were when it came to the installation. They're remarkably shallow (only a 1-3/4" mounting depth), which means they'll fit in a lot of vehicles. In our case, the 1993 Honda Accord we were working on has factory speaker cups that we assumed we'd have to modify with a hacksaw. Imagine our delight when these speakers dropped right in, saving us tons of time and effort.

I installed my Kenwoods into a Chevy Colorado which required some modifications nothing too major just required use of a drill. Years ago I did install 6X9s Eclipse into a 2002 Honda Accord. This was more or less plug and play. I only needed to use the adapters to connect to the speaker harness. The existing factory mounting brackets held the new speakers after some bending with pliers [ GARTH P  Dec 06, 2013 ]
Actually, I returned those speakers. They sounded terrible. You'd be wasting time and money. I recommend Polk. [ Guest  Dec 05, 2013 ]
Yea I installed in a Tahoe crutchfield sent me factory connectors and brackets for free. Sound is great from factory with step by step instructions , I am an experienced installer and can assure you that crutchfield makes it a simple task. Best of luck hope this helps [ DERRY  Dec 05, 2013 ]
An amp could certainly help the system sound better, but these speakers will work just fine with the power from either a factory system or from an aftermarket head unit. [ Jeff  Dec 02, 2013 ]  Staff
