Kicker KSC3504 Dash Center Speaker 3-Point Replacement Kit for Toyota Vehicles

With the factory audio left as-is, I want voices to be easier to hear a bit more.
The navigation guidance, call audio, and the vocal in music sound a little muffled.
This is a replacement kit designed for Toyota vehicles that swaps the total of three positions: the center speaker plus the left and right speakers on the dashboard.

Sound Features

The speakers used are Kicker KSC3504.
By replacing the factory speakers, the definition in the mid and high ranges becomes easier to bring out, making the position of vocals and the attack of sound clearer. While there is still improvement even if you replace only the center speaker, replacing both the left and right as well helps the sound from the front connect more naturally, and during music playback, vocal and instrument visibility improves.

You may not be considering a major change to the audio system, but
if you want to keep the original feel while improving listening clarity,
this is a highly practical and easy-to-adopt upgrade.

Kit Contents

This kit is configured with the mounting panel and connector terminals already installed, making it easier for the work to proceed smoothly during installation. The fact that you can replace the speakers while minimizing modifications to the vehicle side is also important for a car you use every day.

Installation and Compatibility Check

At Log On, we don’t just guide you on replacing the speakers—we also explain how the system connects with the factory setup, how the sound will come out, and installation conditions by vehicle model.
The dashboard speakers may be small parts, but since they affect how navigation audio, calls, and vocals are heard, there can be an unexpectedly noticeable difference in satisfaction after the upgrade.

“First, I want to make the factory audio a little better while keeping it.”
“I want to fine-tune the sound naturally without major modifications.”
“I want music and navigation audio to be a bit clearer.”

This is a just-right factory upgrade kit that’s easy to recommend for people like that.
Compatibility and settings vary by vehicle model, so before purchasing, please check the vehicle model, year, and grade, and feel free to consult us once.
