【KICKER KSC3504 3.5-inch Coaxial Speakers | For Those Who Want to Tune the Sound Naturally with a Stock Replacement】

Are you feeling a bit dissatisfied with the sound of your factory speakers?

The vocals sound muffled, you can’t bring out fine details even when you turn the volume up, and you’d like the high frequencies to extend more naturally. At the same time, you’re not thinking about major modifications or changing the entire system.

That’s where the KICKER KSC3504 is an easy option to consider.

Even with a small diameter, it’s easy to hear the contour of the music

The KSC3504 is a 3.5-inch coaxial speaker.

It’s a size that’s still practical even in locations that are difficult to install larger speakers, and it makes it easier to perceive the subtle nuances of vocals and instruments—so you can readily confirm the change when replacing your factory speakers.

Even with the music you listen to every day, you may notice the singing voice comes a little more forward and the background performance is less likely to get buried. I think you’ll enjoy the difference in sound even during short commutes or errands like shopping.

Rather than strongly emphasizing the treble, the silk-dome tweeter helps the extended high frequencies come together in a relatively soft, well-balanced way.

Slim design that makes it easier to utilize the factory mounting position

The KSC3504 features a slim design that keeps the tweeter protrusion to just 2 mm.

Depending on the vehicle, you’ll need to confirm installation conditions, but it’s designed to fit easily within the factory grille—making it suitable if you want to replace speakers without significantly changing the look.

The woofer uses an internal damping polypropylene cone, and the edge uses a rubber surround. The configuration is aimed at stable reproduction from the midrange through the mid-bass.

However, simply replacing the speakers won’t make them sound exactly the same.

How you install it affects how it sounds

Even with the same KICKER KSC3504, the overall impression of the finished result can vary depending on the stability of the mounting surface, interference with surrounding parts, wiring treatment, and the combination with your factory system.

Especially for the 3.5-inch class, it’s important to install while considering not only the performance of the speakers themselves, but also the vehicle’s existing factory speaker setup and how it connects with the bass.

At Logon, we don’t just replace the speakers—we also:

• what you feel is wrong or lacking in your current sound
• whether you want the vocals to be easier to listen to
• whether you want the high frequencies to sound more natural
• whether you’re considering upgrading your system in the future

We go through these points and organize the best approach together to match your vehicle and how you use it.

If I were choosing the KSC3504, I would first confirm the vehicle-side installation conditions and your current sound. That’s because even without forcing large modifications, there’s a possibility you can aim for a setup where you can enjoy your usual music more comfortably—while still keeping the “factory feel.”

If you want to fine-tune your sound with a factory replacement, if you’re looking for small-diameter speakers, or if you want to start with a reasonable, low-risk first step for your car audio, please consult us including your vehicle model and your factory system. Let’s consider together an installation method that lets the KSC3504 perform to its potential for your car.
