CyberStork JAPAN takes full responsibility for the planning, development, and quality control of its "JOYN" series products. This product is a JOYN subwoofer expansion coupler harness (model number: LPK30) compatible with both the premium audio and Mark Levinson audio systems installed in Lexus vehicles. It is designed to connect to an external amplifier or subwoofer simply by inserting it into the 30-pin coupler connected to the factory amplifier, eliminating the need to modify the vehicle's original wiring. This allows for easier audio expansion while maintaining the reliability of the original system. This product extracts the subwoofer signal from the factory amplifier via a crimp terminal, allowing it to be used directly as an input to an external amplifier or subwoofer. Because the signal is extracted without modification, it allows for natural bass expansion without compromising the original acoustic characteristics. Furthermore, the harness also provides constant power (BAT) and ground (GND), which can be used for remote activation or control of external devices. This eliminates the need to run power from a separate route, reducing the burden of wiring work and enabling safe and efficient installation. The wiring material is designed for conductivity and durability. This product utilizes superior high-purity OFC (oxygen-free copper), enabling stable signal transmission with minimal degradation of sound quality. The coupler uses terminals compliant with the original equipment specifications, ensuring reliable connection and high reliability. This product is compatible with Lexus vehicles such as IS, GS, LS, and RC that are equipped with a 30-pin coupler type factory amplifier. However, even with the same vehicle model name, wiring locations may differ depending on the year and specifications, so please be sure to check compatibility before purchasing. This is an ideal item for users seeking more powerful bass reproduction while maintaining the high sound quality of the original equipment, or for those who want to try DIY audio customization. *Coupler shape may differ depending on the year and grade. Please be sure to check the amplifier connection point on your actual vehicle. *We do not provide support for vehicle-specific connection methods or individual troubleshooting. *If you are unsure about the installation process, we recommend consulting a professional or car audio specialist.
