【KICKER CSS674 Component 2-Way Speakers｜For Those Who Want to Clearly Hear the Difference When Replacing OEM Speakers】

Have you ever felt that the sound from your OEM speakers is somehow lacking?
When you turn the volume up, the vocals get muddy. The bass turns blurry. Only the high frequencies stand out.
Even just swapping the speakers can make a big difference in impression.

KICKER CSS674 is a component 2-way speaker that’s easy to choose as an upgrade from OEM.
Not only for those who want to listen clearly from the front seats, but it’s also a great match for anyone who wants to enjoy music comfortably on commuting and drives.

More than just loud—an upgrade that changes how easy it is to listen

The appeal of this model isn’t limited to having energetic sound.
Vocals are easier to bring forward, and the rhythm is easier to catch.
Subtle details that tend to get buried with OEM speakers become more noticeable, so even your usual songs feel like, “So it was in there like that.”

The tweeter is a small speaker responsible for the high frequencies, and it plays a key role in sound definition and clarity.
With the CSS674, you can switch the tweeter level in three steps, making it easier to fine-tune the balance according to cabin reflections and installation position.
In cars where the highs are too strong, you can calm them down.
Conversely, in cars where sound easily feels muffled, you can brighten it a bit.
By making these adjustments, you don’t end up with a “simple swap”—you can also shape the sound into something easier to enjoy inside the car.

Satisfaction during the drive changes

What tends to show the biggest difference with a speaker replacement isn’t so much sound volume as whether you can listen to it comfortably.

For example:

• Navigation voice becomes easier to understand
• Vocals come together more in the center
• Bass is less likely to drag, bringing out a stronger sense of tempo
• Even at lower volume, the amount of information is harder to lose

These kinds of changes build up gradually with every day of driving.
Not overly flashy, yet you can clearly feel the difference from the OEM setup.
CSS674 is an easy-to-recommend model as a practical upgrade like that.

Professional shop installation greatly affects the final result

With speakers, sound isn’t determined by product choice alone.
Where and how you install them.
How you match them to the conditions on the door side.
In what direction you mount the tweeter.
These factors can change the finished result considerably.

At LogOn, it’s not just a matter of mounting and finishing. We build it up using a reasonable approach while checking the vehicle’s structure and the OEM condition.
By carefully handling even the parts you don’t see—such as securing mounts and wiring, installation angles, and how the sound connects—you help bring out the product’s true strengths.

In particular, component 2-way systems can vary dramatically depending on how the woofer and tweeter connect, so this is a category where differences in installation and tuning show up easily.
Even with the same speakers, when installation and tuning are well-matched, you’ll clearly notice improvements in sound cohesiveness and reduced fatigue.

A model that’s easy to consult even with your OEM audio

“Not considering a large-scale system.”
“First, I want to start with replacing the speakers.”
If that sounds like you, CSS674 is a model that’s also easy to introduce.

One good thing about speaker replacement is that you can feel the change in sound even while using an OEM head unit or OEM navigation.
Depending on the vehicle, installation methods and required materials can differ, so planning ahead—including how it will look when installed and future expandability—helps you choose with fewer regrets.

For your first audio upgrade, what matters is not just the product itself, but “how it will turn out in your own car.”
At LogOn, we can propose a no-stress way tailored to your vehicle, how you use it, and your preferences.

If you’re undecided, we recommend choosing with a consultation first

The KICKER CSS674 is a component 2-way speaker that makes it easy to feel the change when replacing OEM speakers, and it’s also easier to balance lively sound with listenability.
From commuting and pick-up/drop-off to weekend drives, if you want to make your usual time in the car a bit more comfortable, this is a very easy one to choose.

It’s not just about swapping and calling it done. Install it properly to suit your vehicle and tune it so it’s easy to listen to.
Only once you include all of that do you end up with a satisfying speaker replacement.

I want to improve the sound, but I don’t know what to choose.
That’s okay—even at that stage.
We can guide you with information that’s safe to start with, from a place that’s practical for you.
