【Single Replacement Kit for 4Ω Center Speaker for Toyota Vehicles｜KSC3504】

This is a single-center-speaker replacement kit designed to swap the factory center dash speaker in a Toyota vehicle to the KSC3504.

It’s suited for those who feel that voice guidance, hands-free calling, vocals, and other audio from the factory speaker are a little hard to make out. By replacing the center speaker, the vocal frequency range can come through more clearly toward the front, making not only music but also navigation announcements and call audio easier to hear in a more natural way.

This kit comes with the mounting panel and connector terminals already installed. You can replace the factory speaker smoothly while keeping vehicle-side modifications to a minimum.

“First, I’d like to slightly improve the sound from my factory audio.”
“I don’t need a full speaker replacement right away, but I want to improve how clearly I can hear voices.”
“I’m wondering whether I really need the 3-piece set.”

For people like this, there’s also an option to start with a single center speaker. In particular, if you often use navigation voice guidance and hands-free calling in your daily driving, this is where you’re likely to notice the difference after the upgrade.

However, for Toyota vehicles, compatibility may vary depending on model year, grade, and the specifications of the factory navigation/audio system. Before purchasing, please confirm not only the vehicle model, but also the vehicle type/grade code and the specifications of the factory system.

At LOGON, we review your vehicle’s condition and how the current sound comes through, and we help you sort out whether replacing only the center speaker is enough or whether you should consider the front speakers as well. If it were me, I would first check your usage situation and the factory system, then make changes starting with areas where the benefits of spending money are easier to understand.
