I have the siruis satellite radio in my truck, and I was wondering if anybody else has the same problem as me. I know that you have 4 choices of FM band to change to when the signal is not strong. If I am on the best signal it seems as if the volume isn't as loud as a CD. Is this an occuring problem or is there anything that I can use to boost the volume or is there any changes I can make to the radio.

I have a stock radio in my truck.

 

My PnP tuner has way more than 4 choices for channel. I'd lpick up a wired FM modulator from Best Buy, Circuit City.
