Kenwood Tuner Amplifier with internal Bluetooth 4.0(KRC-86B)

**Working with electricity is dangerous. If you decide to attempt the following modification to your system, you do so at your own risk. Please use caution. Touching the wrong place can result in becoming acutely aware of your surroundings or cause death. ** Just a quick video showing the ability of the KRC-86B receiver board. This project was intended to semi permanently mount a Bluetooth into the internal case of the stereo so as not to have extra components to plug in. This was done with a 12V 3A SMPS, a buck converter(12V 3A reduced to 5V), a prototype or "perf" board, assorted wires and of course the KRC-86B Bluetooth 4.0 receiver board. Yes, the powers supply may have been over kill, but I was trying to dumb this process down so you don't have to be an engineer to install it, just careful and studious. The SMPS is connected to the buck converter, the buck converter supplies the 5V to the KRC board, and the KRC board is supplying the audio input to the CD input on the Kenwood(externally for now, but will be wired to the foil side of the board). I will also be adding a 250VAC switch to the ground side of the SMPS so I can turn off all the power to the Bluetooth system and eliminate any distortion while using the FM stereo. So far, I have not noticed the SMPS causing any interference with the FM signal receiver. I will post another video when it is finished. ... https://www.youtube.com/watch?v=s6ETSaKs2bo
