Detailed tutorial on audio rf modulator uses in car and home

I go over all the basics in the tutorial how an rf modulator works and how it is wired in detail.

Thanks for uploading! Can this work on an old analog dial tuner? Is it possible to buy an RF modulator that has two separate inputs? I want to add a 3.5mm AUX/iPod input under my dash and have a 5 disc changer mounted in the trunk of my car and using a switch mounted under my dash to actuate between CD and iPod. This is in a 1977 Lincoln Continental with original quadraphonic 8track player that I want to keep. I also want to add a powerful amplifier and possibly a small sub-woofer. Any advice?
