Review on High-Performing CRUX SOHTL-20 Radio Replacement Interface for Toyota/Lexus with JBL System, Black by Drew Panah

This product works great. Used it on a 2004 Tundra ATV. The gain adjustment for the factory amp input works as advertised. gives more flexibility to the input level of the amplifier. It should be noted that the Tundra factory amp is very sensitive to high gain and will shut down if the input volume is too high. He has a protection system for that. The circuit diagram is easy to follow. There is a problem with the color coding. A wire was not considered. but it was not necessary for this application.
