【LEXUS Start-Up Sound Upgrade Circuit｜Enjoy Genuine Styling Even with Aftermarket Audio】

The start-up sound that plays when you close the LEXUS doors and turn the key ON. When you hear that sound, don’t you feel like, “Yes, I’m really in a LEXUS”?

However, in car audio systems that combine aftermarket speakers, DSP, and amplifiers, the linkage with the OEM system may change, and the start-up sound might not be playable.

So, at Logon, to let you enjoy the LEXUS start-up sound even with an aftermarket audio system, we designed an original circuit from real vehicle data.

A More Refined Sound While Keeping the Genuine Feel

This circuit is not only for playing the start-up sound.

By adjusting the start-up timing to match the vehicle’s behavior, it enables you to enjoy LEXUS-like presentation even with systems that include aftermarket DSP and amplifiers.

Furthermore, by shaping the sound impression according to the performance of the speakers and amplifiers, it’s also possible to deliver a clearer, fuller resonance while still respecting the genuine atmosphere.

Because it plays briefly every day when you get in the car, differences in sound quality and timing greatly influence the overall impression inside the cabin.

Recommended for People Like These

• After installing aftermarket speakers or a DSP, the OEM start-up sound can no longer be played
• Even after replacing your car audio, you want to keep the LEXUS-like presentation
• You want to fine-tune the start-up sound so it matches your current audio system
• You want to pay attention to the details without losing the genuine feel
• You want to value not only the sound, but also the satisfaction you feel the moment you get in the car

A Circuit Designed with Installation and Tuning in Mind

A start-up sound is not something that’s solved just by adding a circuit.

Depending on the vehicle specifications, your current audio setup, and the combination of DSP and amplifiers, the way the system operates and how the sound is tuned will change. Rather than deciding everything by email, it’s safer and less likely that details will need to be changed later to move forward while confirming the actual vehicle and system.

At Logon, we don’t just make sound work—we guide you by confirming the relationship with the OEM system, the start-up timing, compatibility with your existing audio, and even day-to-day usability after installation.

If I were doing an aftermarket audio setup, I would want to finish it not only for the music I usually listen to, but also including these fine, LEXUS-like touches.

If you want to keep the OEM start-up sound, or if you can no longer play it due to replacing with aftermarket audio, please consult us with your vehicle model, year, and current audio configuration. Let’s decide the direction together in a realistic way while checking the actual vehicle.
