  • FM Modulator Question

    I am using a hard wired fm modulator for my XM radio. I have not had any problems with it at all. I just recently installed another one to add RCA jacks. I Used the same 12 volt source as the XM fm modulator. The new fm modulator that I have has a kill switch and everything works fine when it is on. The problem that I am having is that when I am just listening to a CD and then I turn off the car the radio will stay on for about 5 seconds after the car is off and the key is out. If I keep the new fm modulator on it will turn off normally it is just when you turn that fm modulator there is adelay before that radio will turn off. What is going on with it? I am thinking that I will hook up the new modulator to a different 12volt source. What are some good 12volt sources in the car. Thanks for the help.

    You did not specify what was the first 12v source.
