I have been browsing through the forums to try to find the best solution to feed in the audio signal for a portable satellite radio, but there seems to be many options. I am looking for a way to hardwire the audio signal into the radio without having to get an interface module, but I didnt see any information on it. I currently have it installed using an audiovox wired fm modulator, but the AM frequency is diminished. I keep trying to tell the customer (my uncle) that AM is a dying frequency and a modulator can cut down on the signal strength, but he really wants the AM back.. Worst case scenario, ill purchase him an auxillary interface module.

 

Not sure what car or model you have but there's many options. Soundgate, Pie, blitzsafe etc. All comes down to your needs and personal preference.
