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 Kenwood Excelon KFC-X173

by Buck Pomerantz

Kenwood Excelon speakers incorporate technical know-how and advanced materials to give your music the full, rich sound it deserves. These full-range speakers sport a diamond-array pattern etched into their woofers that increases the strength of the carbon-polypropylene cone for improved dynamic response and lower distortion. The butyl rubber surround resists weathering, providing reliable support that keeps your music playing, no matter what.

The KFC-X173 6-3/4" full-range speakers feature 3/4" silk dome tweeters that deliver all the high-frequency details without sounding harsh. Because of their specially designed magnetic circuitry and neodymium magnets, these compact tweeters use less steel in their construction than most tweeters, so you'll hear more accurate response.

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 of Carbon-PP (polypropylene) with a diamond array pattern. The woofers feature butyl rubber surrounds for a smoother response and improved durability.

Tweeters: Each speaker uses a 3/4" Silk soft dome tweeter for smooth, accurate highs.

Adapter Ring: The included adapter ring expands the speaker's compatibility to include the 3-hole 6-3/4" patterns used by GM and Chrysler, the standard 3-hole 6-1/2" pattern, and Ford's 4-hole 6-1/2" pattern. Using the adapter ring adds 0.274" to the mounting height and subtracts 0.274" from the depth. Given the 4.916" cutout required, the speakers will also fit in standard 6-1/2" openings without the adapter ring, but new screw holes must be drilled.

Warranty Note: Although these speakers come with a 1-year warranty card, they are covered by the Kenwood Excelon 2-year warranty.

Very pleased

Installed in a 2008 Chevrolet Silverado

Crutchfield Customer Review (What's this?)

I got these speakers very quickly, with only a delay from UPS due to a noreaster of one day. The extras that came with the speakers from Crutchfield made all the difference in the world in the install. The mounting brackets that came with the speakers would have worked but not nearly as nicely as the ones from Crutchfield. The wiring harness was great. Didn't have to rely on cheap crimp butt connectors or the hassle of soldering. Just plugged right in. With taking the door panels off, installing the speakers and reinstalling the door panels only took 15-20 min per side. The only thing I had a problem was that the instructions for a 2008 Chevy Silverado didn't show me there was two more screws holding the door panel on behind the handle accent piece. Once I realized they were the it was a piece of cake!

Pros:

Great fit, Great sound and Easy install. Mounting brackets fir perfect and wiring harness made the job take no time with no worries of connections becoming loose.

Cons:

Makes me want to spend the money and do the rest of my speakers. The Instructions didn't show two screws behind the door handle on the door panel.

To me it didn't have enough highs, after I added add-on tweeters sounded way better.

Kenwood Excelon KFC-X173

Written By LarryD, Kaneohe, HI on Tuesday, September 21, 2010

I just bought two pairs of these for my Dad's car, along with one of Kenwood's excelon receivers. I've gotta say, these seem to be quite good speakers for their class. The separation and space to the music is very nice. Highs and mids are smooth and clear. If you're looking for crazy bass from these, don't expect much if you're not using an amp. They're only running off the receiver, but these things feel like they're just dying for the spanking an amp would give 'em. Only negative I've noticed about these so far is they seem a bit syllabic, but nothing that was too offensive.

If you're looking for good sound quality in this price range, these will make you smile.

Welcome to the world of aftermarket speakers

Written By TJ, Houston, Tx on Saturday, July 17, 2010

Installed in a 1999 Toyota Corolla

I bought these speakers on a kenwood excelon system deal and was quite skeptical, and although it said they would fit, I had to modify some of the screwholes to get these in.

Running off of the head unit, The highs and mids were wonderful, and sounded 10 times better, but my stock rear speakers were much more sensitive and handled the bass much better.

Then, my 4 channel jl audio amplifier arrived. And the mids and highs are so clear that it makes me shiver. Not to mention I can turn them so loud.

Also, the bass I was enjoying before is back, but now tighter and much more clean.

Wonderful pair, and Im happy I get to review them and hope that people share in this purchase.
