【KICKER KSS504 Separate Speakers｜Make Factory Audio Easier to Listen To】

Do you feel like the sound from your factory speakers is a bit lacking?

When you turn the volume up, the sound becomes rough. The vocals get buried. Even though you have bass, it somehow lacks tightness.
For those who want to improve and balance the sound in the car without unnecessary hassle, KICKER KSS504 is an easy option to consider.

More Naturally Notice the Contours of Vocals and Instruments

The KSS504 is the kind of separate speaker that doesn’t dramatically change the sound, but makes the music you already listen to feel more comfortable and easier to enjoy.

From the midrange down to the bass, there’s a solid core, making the positions of vocals and instruments easier to understand. Even small details that are often lost or buried with factory speakers become easier to pick up within the music.

A silk dome tweeter is used for the high frequencies. It’s designed so that the highs don’t come out too strong, making it easier to tune the system toward reduced listening fatigue even on long drives.

The woofer uses a polypropylene cone and a rubber surround, providing the foundation from the midrange through the low frequencies.

Because It’s a Separate Type, Sound Changes Depending on Mounting Position

The KSS504 features a separate configuration: the woofer and tweeter are independent.

Depending on where you install the tweeter and in what orientation, the way vocals come through and how the sound spreads will change. Even with the same speakers, the way you hear them inside the vehicle varies with the installation method.

At Logon, we plan the installation approach while considering each vehicle’s mounting conditions and how well it matches the factory location—taking care with not only appearance but also day-to-day usability. If you’re going to replace your speakers, we want to care about the finishing details so they sit naturally in the cabin, not just the sound.

Speaker Replacement Is Something to Consider Including Installation and Tuning

Simply replacing the speaker units can sometimes improve the sound. However, differences in installation conditions inside the door, the mounting foundation, wiring treatment, and the way surrounding parts are used will affect the final result.

Also, how you can take advantage of the KSS504 will vary depending on the combination with your factory navigation system and existing audio system. If you want to consider everything from the sound’s attack to vocal imaging and how it connects with the bass, tuning after installation is also important.

If it were me, I wouldn’t decide purely based on the price or specifications of the speakers alone. I’d first organize what level of sound improvement you want with your current car—whether you’ll keep it simple by using the factory navigation and only replacing the speakers, or whether you’ll build the sound further with an amplifier and DSP. Choosing the direction together based on how you use the car and your budget is a way to minimize regrets.

KICKER KSS504 Is a Good Fit for People Like This

• Want to achieve sound with more information than with the factory speakers
• Want vocals to be a little easier to hear
• Don’t like sound where the treble gets too harsh
• Want not only more bass quantity, but also better cohesion
• Want to improve sound without dramatically changing the look
• Are replacing speakers for the first time and want advice on choosing what fits your car
• Want to enjoy the music you always listen to more comfortably

Whether the KSS504 will suit you also depends on your vehicle model, your factory audio specifications, and what you dislike about your current sound.

In some cases, simply replacing the speakers is enough for full satisfaction. In other cases, it may be better to combine door-side treatments and use an amplifier and DSP. At Logon, rather than deciding on products first, we guide you to a reasonable, no-stress configuration while confirming your car and how you listen to music.

Since you listen to music on every day’s drives, it’s important that vocals and instruments reach your ears naturally without having to turn the volume up. Let’s create together the kind of in-car sound you’ll enjoy—right down to how you install and tune the KICKER KSS504.
