[LEXUS Start-Up Sound Upgrade Circuit]

The "key-on startup sound" is a symbol of LEXUS.
It originally works in conjunction with the factory system, so it cannot be played with aftermarket audio or a custom system configuration.

So, our shop designed a new, original circuit based on actual vehicle data.
We have commercialized the "LEXUS Start-Up Sound Upgrade Circuit," which starts up accurately with the same timing as the factory sound, while further improving sound quality.

This circuit does more than simply "reproduce the factory sound."

It optimizes the startup sound itself to sound more luxurious and high-quality, matching the performance of your speaker system and amplifier.
It creates a level of luxury while maintaining the factory atmosphere.

✔ Reproduces the original startup sound even with aftermarket speaker/DSP/amplifier configurations

✔ Achieves operational linkage with the vehicle through a unique design (including delay adjustment)

✔ Sound quality tuned even further than original for a clearer, richer sound

✔ Can be installed without special processing (vehicle-specific harnesses also planned)

✔ Adds even more luxury and satisfaction without losing the LEXUS worldview

The moment you close the door and turn on the engine, you'll experience a new experience that lets you enjoy a "LEXUS that goes beyond the original."

A one-of-a-kind upgrade item that also meets the "attention to detail" demanded by luxury car owners.
