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

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.

Crutchfield Customer Review (What's this?)

Used to replace 8 year old JBL Inifinity 3k700 Azera speakers. Glad I replaced only one of the originals and did a side by side comparison. The Kenwood may sound ok by itself.... But in comparison to the 8 year old JBL it sounded like a tin can. I can not recommend the Kenwoods and am looking for a JBL replacement.

Pros: Reasonable build

Cons: Maybe be ok if nothing else to compare to. Otherwise I suggest JBLs. I want to return them for my money back.

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

Written By Kenneth, Tennessee on Wednesday, September 30, 2015

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

Crutchfield Customer Review (What's this?)

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
