So, you're finally ready to do something about your ragged factory speakers. The beauty of Kenwood's Sport Series speakers is that you can seriously improve your sound without breaking the bank.

Sweet sound

The KFC-1665S 6-1/2" 2-way speakers feature polypropylene cones that will enrich your music with all the midbass and midrange details, while the 1" balanced-dome tweeters will make high notes soar. Kenwood also includes sharp-looking grilles in case you're doing a custom installation in your vehicle. Finally, you can enjoy your music the way it was meant to be heard, with clarity and emotion.

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.

Kenwood KFC-1665S

Written By BryanR, Iowa on Wednesday, September 30, 2015

Crutchfield Customer Review (What's this?)

Easy install if you check the box for a conversion kit first, which I did not!!! Sound is pretty good, bass could be a bit better but all around great speaker for the price.

Pros: Good price, easy installation

Cons: some sound quality issues at higher volume

Not That Great

Crutchfield Customer Review (What's this?)

Realize they are cheap speakers. Not happy with the sound and they won't take much volume out of my kenwood without distorting and bottoming out. I am returning these to try something different.

Pros: price

Cons: sound

These speakers sound great and for a great price. They are very easy to install with the brackets and wires that crutchfield sends with them.

Pros: Easy installation. Great sound.

Cons: None

Crutchfield Customer Review (What's this?)

Good for what they are and shallow fitment for Honda worked great.

Pros: Construction, sound, shallow fitment

Cons: They are what they are for being size limited

Not enought power

Bang for the buck, but not thump for the buck...

Crutchfield Customer Review (What's this?)

These are great little replacement speakers... but if you are looking for any thumb, you will need a sub. I will bet they will pair nicely with any number of powered subs.

Pros: Ease of installation, crisp top end.

Crutchfield Customer Review (What's this?)

Purchased these speakers for replacement only, after a quick replacement they sounded a little better than stock speakers, I was however impressed with the shipping time. I would recommend these as replacement items.

Pros: Fast Shipment, well packaged, instillation kit included.

Cons: Not premium sound but do work well with my system.

Reasonable price, average performance

For the price, about what one would expect.
